Due to the processes involved, many industries such as oil and gas, chemical and petrol-chemical, energy or pharmaceutical industries may encounter flammable substances (gas, vapour, mist, liquid, dust, small fibres) and could involve an explosive atmosphere. Where dynamic performance or compact dimensions are required, servo motor technology provides the best solution. Parker has developed specific ATEX Permanent Magnet AC (PMAC) motors where compact dimensions and dynamic response with torque, speed or positioning control are required. These 10-pole servomotors are up to five times more compact than comparable asynchronous motors.
Parker’s EX series is also ideal for applications that include: filling machines in the packaging sector, oil and gas valve actuators, automotive paint shop robots and feed mills in the food sector.
What is an explosive environment?An explosive atmosphere is a mixture of air and flammable substances such as gas, vapour or dust under atmospheric conditions that can explode, where for an explosion to occur, three circumstances must be fulfilled: the presence of fuel, oxygen and a source of ignition. Ignition sources, such as flames, electric arcs and sparks, ultrasound, chemicals or electromagnetic radiation have the potential to cause an explosion in certain circumstances.
Parker EX servomotors, characterized by excellent motion quality, great acceleration/deceleration capabilities and high torque output over a wide speed range, are specifically designed to follow the European ATEX regulation for explosive atmospheres, based on the following European directives:
1- 1999/92/EC: Under the end-user responsibility, 1- 1999/92/EC regulates worker safety and explosive zone classification. EX servomotors are designed and certified to be safe under normal operating conditions both in a place where an explosive atmosphere is likely to occur only occasionally (between 10 to 1000h/y) as well as in a place where it can occur for a very short period (>10/y) (see left-hand side of the chart below).
2- 2014/34/EU: Under the supplier's responsibility, 2- 2014/34/EU regulates the device's design compliance for operation in explosive environments. EX servomotors are designed to guarantee safety with a high level of protection, giving single fault tolerance. (see right-hand side of the chart below).
EX servomotors are ATEX compliant for operation in surface industries (Equipment Group II) and in accordance with given levels of flammability for substances present in the atmosphere, such as propane (IIA), ethylene (IIB), Hydrogen & Acetylene (IIC) regarding gas reference and combustible flying (IIA), non-conductive dust (IIB) and conductive dust (IIC) regarding dust reference. While the temperature classification is T4 (135°C).
In 2016, Parker extended the EX servo motor compliance to the IECEx standard as well as to the regional Kosha certification for the Korean market. More recently, EX servo motors have been CCC certified to guarantee compliance with Chinese legislation, where CCC certification is mandatory for explosion proof products (Ex products). Apart from the specific nameplate, CCC motors have the same construction as IECEx motors. They are intended for use in the same areas (gas or dust) and have the same degree of safety.
As an option, Parker offers a version of the EX series that is certified UL for the North American market in accordance with the UL674 standard. Importantly, Parker’s extensive portfolio of ATEX-rated motors, gearheads and actuators ensures the right combination of application-compatible products can be selected every time. Various winding variants and numerous options are available to offer maximum flexibility.
The precision helical gearing design of the GXA gearbox series associated with the powerful Parker ATEX servomotors range offers smooth and quiet operation for the most demanding high-performance applications. Finally, our well-known ETH electro cylinder range for explosive atmospheres are certified for use in explosive gas atmospheres (device group II, category 2G)

How to Achieve Safe Motion Control in ATEX Environments
For some patients with impaired physical function, rehabilitation equipment can help them to carry out appropriate exercise training, prevent muscle atrophy, improve muscle strength and upper and lower limb motor function. Parker Hannifin can provide safe, stable, and reliable precision motion control for rehabilitation equipment, help people carry out reasonable and effective rehabilitation training, and improve the quality of life.
Recently, Parker's Compax3 Servo Controller has found a new purpose in healthcare and life sciences markets where precise and safe movement is paramount. The drive's flexibility, accuracy, and comprehensive list of safety features have led to its adoption in positioning tables, exercise equipment, and therapy devices. At present, Parker's technology has played an important role in the upper and lower limb intelligent feedback training system launched by a Chinese medical equipment manufacturer.
Finding a safe way to control movement, force and positionGuangzhou Yikang Medica Equipment Co, Ltd was developing a multi-joint and exercise system. This new medical device is suitable for the training and rehabilitation of upper and lower limb dysfunction caused by nervous system damage. It is more focused on early rehabilitation training, with passive and active training modes to help patients quickly return to a high quality of life.
The customer worked with Alan Tan, territory sales manager to review the variations in flexibility from patient to patient due to injury and age. They really required a smooth movement to avoid further risk to the patient or injury. The team also desired a way to accurately control the force and position during operation. The safety of the patient, therefore, was paramount.
The new rehabilitation device is equipped with Parker's
Precision Inline Planetary Gearheads - PV Series (PV reducer).
The servo drive is equivalent to the human body's "nerve center", which converts the received signal into a "language" that the motor can understand and execute, so as to precisely control the position, orientation, and state of moving parts.
Existing products find new application for delivering safe and effective motion control
The Compax3 Servo drive is far from a new product. Developed by the Electromechanical and Drives Division Europe, Parker's global servo drive platform is widely used in industrial manufacturing to control motorized processes in automated assembly, including robotics and the machining of parts. Parker's customers are well-acquainted with the benefits of the drives used in packaging, the production of sheet goods, and the operation of printing presses, as well as automated testing equipment for both automotive and consumer goods.
For rehabilitation equipment, safety, stability, and reliability are of the utmost importance. Compax3 has excellent electromagnetic characteristics, low electromagnetic radiation; with leakage current protection, and outstanding protection characteristics that can provide a safety guarantee for the equipment. At the same time, it has a built-in programming function that can help users easily achieve complex and diverse personalized control requirements.
In rehabilitation treatment, the intensity and training mode required by different patients and the rehabilitation process are different. Compax3 has fast response speed and powerful functions. Users can not only switch quickly between active and passive training but also make real-time dynamic adjustments during training.
Different flexibility settings can also be set according to needs to achieve gentle movement of muscles and joints. At the same time, in the process of position control and force control switching, there is no overshoot problem. With the smooth-running SMB motor, the equipment runs safely, reliably, and stably, with low noise, and brings users a comfortable and stable recovery experience.
It is not difficult to imagine that in the process of building a higher quality of life for people, such equipment has become an indispensable part. As a pioneer in the field of motion and control, Parker Hannifin has always insisted on "taking purpose as the leading", using core technologies to help industry customers solve the challenges they face, jointly guarding people's health and safety, and achieving a better tomorrow!

How Collaboration With Manufacturers Will Help You Perform Better
Automotive metal stampers' subtle shift from mechanical to hydraulic to servo press may be largely imperceptible, but it is there.
The global servo press market, valued at about $596 million, is expected to grow to more than $710 million by 2026, according to 360 Market Updates.
Stampers are attracted to the servo press's speed and versatility. They boast full working energy at any speed while managing difficult manufacturing processes and various materials. Servo press technology allows for varied speed during the stroke, providing better part ejection, material feed and tool close capabilities than either a traditional or hydraulic press.
But the hydraulic press isn’t going anywhere. In fact, the hydraulic press market is expected to grow by $1.89 billion by 2024, according to Global Hydraulic Press Machine Market 2020-2024. They remain a budget-conscious stamper’s top pick, and possibly the only solution for jobs that require high force demand early in the stroke.
So how real is the stamping shift? And which technology is best suited for metal forming in the automotive industry?
Automotive metal stamping today
Automotive metal stamping is a $40 billion industry today, employing more than 115,000 metal stampers at more than 700 metal stamping companies and automotive stamping plants in the United States. Sheet metal sub-assemblies have become a critical peripheral of the automotive industry, stamping parts and sheet metal components for multiple plants and varied products.
Within a typical plant, stamping presses are turning out several automotive components daily, from body panels and chassis to brake and lighting parts. Those presses likely include both hydraulic and servo presses, depending on the requirements of the job.
And because of the range of metal that can be successfully formed by traditional stamping presses, allowing manufacturers to create high-quality metal parts at affordable prices, those machines will likely live on the plant floor for a long time to come.
The ability to successfully press different alloys, from stainless steel to aluminum, is vital for auto manufacturers. Consumers are demanding fuel-efficient vehicles that look like gas-guzzling muscle machines and sleek, fuel-burning sports cars. Other drivers want electric vehicles that can move like traditional cars and trucks. Those demands require manufacturers to find solutions that:
To meet those demands, and give customers the experience they want, auto manufacturing companies are turning to new technology to make it happen.
Servo press versus hydraulic press: Benefits to consider
Most stampers will tell you choosing between a servo press and a hydraulic press isn’t a matter of knowing which is the better machine. It’s the ability to select the right tool for the job.
Servo presses tend to produce greater cycle speeds than their hydraulic cousins, often reaching speeds typically reserved for the traditional mechanical press. But in some stampers’ viewpoint, the hydraulic press’s ability to provide full tonnage and energy through the stroke gives them advantage.
Choosing the right press really comes down to what you’re asking the press to do. To make the right decision, consider these attributes:
The bottom line? Both servo presses and hydraulic presses balance each other – and the needs of the automotive stamping plant – when employed for the right job.
Parker solutions for automotive stamping
Whether they are traditional, hydraulic or servo, keeping presses up and running will always prove a challenge for stampers. To help ensure the longevity of each machine, Parker provides solutions, assistance, and a wide array of components for all press motion and control needs used in the metal stamping portion of the automotive industry.

Today’s challenge for engineers is to continually improve the performance of electric vehicles. This is done through a process of incremental refinements that add up over time. One critical component being looked at consistently is the electric motor and the means by which power is transferred from the battery pack to the traction motor through a gear reduction to the wheels. These components are expected to offer high torque and power density along with other capabilities such as high reliability and low noise.
Using a frameless kit motor can have huge appeal for engineers working on e-mobility drivetrain programs who are often seeking greater design flexibility in ways that allow them to reduce the vehicle size and weight.
What is a GVK?Designated as the Global Vehicle Kit (GVK) motor range, the ‘kit’ form of Parker's Global Vehicle Motors (GVM) including only the active magnetic parts of the GVM motor. With the scalable nature of the GVM product family, we can provide solutions from 3kw continuous to 225kw continuous at voltages up to 800VDC
Assembled into the vehicle sub-component by integrating only the active magnetics, and patented cooling, it can simplify mechanical, electrical and cooling interfaces. This reduces space claim, number of parts and failure modes.
Frameless kit motors guarantee the same performance as standard GVM motors and can be the ideal solution for high-volume vehicle sub-components that require high performance in small spaces.
The frameless approach offers many advantages over traditional technologies, thanks to a more seamless mechanical and electrical adaptation to the application requirements. This can lead to a highly efficient and dynamic design. It can, for instance, offer some real benefits in terms of compact sizing, allowing integration in the same space with the gearbox. There are also weight and complexity reduction advantages that are achieved by eliminating the motor frame as well.
“Kit” or frameless motors are the ideal solution to meet light weighting objectives, especially for high-volume applications. Examples include integration into drive train assemblies like transmissions, axles, for truck, bus, construction and mining vehicles. Kit motors are also great solutions for smaller autonomous vehicles used in warehouses and last-mile delivery vehicles
Light weighting is an important design process used by automotive engineers that is especially important to employ in all on-highway and off-highway hybrid and electric vehicles to increase range, performance, productivity and reliability, while reducing space and weight.
Once the OEM chooses the specific solution the more integrated nature of the design means it is easier to mount the motor, and more compact than using equivalent fully housed motors. The reduction in the number of components used means they can deliver lower overall design costs.
GVK is a flexible design solution, leveraging our proven high-power density, high efficiency magnetic and cooling designs, flexible manufacturing processes, that will reduce design risk and time to market.
ConclusionCrucially, Parker works closely with customers to ensure that the right PMAC motor is selected for a specific application’s needs. This collaborative approach involves taking an informed view from the outset on how the main elements – the stator and rotor – can be seamlessly integrated into the broader vehicle platform.
This solution offers inherent advantages for the end-user, just like the GVM, that include reduced fuel consumption, reduced emissions, quieter operation and a downsizing of the power system.
Overall, direct drive motion construction gives equipment designers the advantages of lower costs, increased reliability and better performing vehicle that is closely aligned to the specific needs of the greener vehicles of tomorrow.

How to Take Advantage of an Electric Power Take-Off
With the increased emphasis to reduce emissions, air pollution, resource waste and traffic noise, government legislation is pushing towards the use of electric power to drive ancillaries in work trucks.
This is particularly relevant in construction, materials handling and refuse collection applications operating in urban areas. Adopting electric power take-off (ePTO) as an alternative to the traditional PTO from an internal combustion engine (ICE), brings multiple benefits to the application, the operator, and the environment.
Why switch to electric?
Historically, the PTO output shaft has been part of the internal combustion engine or transmission, which requires the engine to be idling during use. An idling engine can produce up to twice as as much exhaust emissions as an engine while driving.
ePTO makes the vehicle environmentally friendly and is the first step towards hybrid and all-electric powertrains. Decoupling the auxiliary functions from the ICE allows independence with the speed of the diesel engine, ensuring work is carried out in the best yield zone with higher efficiency and less fuel consumption.
The reasons for this development are clear. The strengthening of environmental rules for fine-particle and noise emissions and the constraints imposed by prime contractors for urban work sites increase the sense of urgency.
Added benefits of the diesel engine can be a smaller footprint and fuel consumption savings. For example while driving (traction + PTO) and in town, the diesel engine can be switched off and the ePTO can be used. As a result, the reduced noise at the work site improves communication and therefore safety.
What is ePTO?
The ePTO system consists of an inverter and an electric motor powered by a DC power source, for example, a battery. Running auxiliary loads from the battery removes the need to idle the engine during PTO, which reduces fuel consumption, and eliminates air and noise pollution. Similar to a standard PTO, it can be connected to a mechanical transmission system (cardan shaft or gearbox) or to a hydraulic pump. This, however, creates new demands on the hydraulic pump and motors with opportunities for further improvements in efficiency and noise.
There are several solutions to power the ePTO. The first is using a rechargeable battery, which has the capacity to complete a day’s work and can be recharged overnight, benefitting from lower energy price, or using ‘green’ energy.
Alternatively, the battery can be charged using a generator, which is driven by the ICE. This solution is most suited to stop-start applications, such as a refuse truck. Because the battery can be regularly recharged, its size and weight are reduced, but it is still expensive.
ConclusionWhile all-electric is not easy to implement on large mobile machines, the electrification of auxiliary loads is profitable, while reducing or eliminating idle time.
As stated previously, power demand from the ePTO can differ depending on the application.

New Motor and Generator Solution Supports Cleaner Vehicles of the Future
Electrification Lightens the Load in Heavy Lifting Tasks
Since its industry introduction in the 1960s, automation has made an accelerated climb to be a significant trend in material handling applications. Now, automated material handling systems handle a wide range of repetitive and precision tasks in manufacturing and supply chains, along with the eCommerce, logistics, and retail industries.
These systems offer a range of benefits, including increased productivity, cost control, worker safety, reduced product damage, and more. And as companies expand, they can invest in additional machinery to keep up with demand without worrying about labor shortages.
Download our white paper Off-Road Trends: Driving Cleaner, More Efficient and Connected Machinery, to learn more about trends in the Material Handling industry.
Key trends in automated material handling
Among the significant equipment trends in material handling are the following:
Automated storage and retrieval systems (AS/RS): This refers to a variety of technologies that can handle, store, and retrieve material with precision, accuracy, and speed. These systems are used in applications ranging from assembly and production (retrieving and delivering parts for assembly) to retail (bringing parts to the point of sale).
Automated guided vehicles (AGVs): These computer-controlled and wheel-based machines travel along the floor of a facility without a human driver. They handle a variety of applications, including material transport, pulling trailers or forklift work. These are typically battery powered and controlled through a combination of programmed software, vision systems, and sensor monitoring.
Material handling robots: Robots are used in a wide range of applications and come in a variety of designs. Reach distance, payload capacity and the number of axes of travel is defining characteristics of different models. Robots use what’s known as the end of arm tooling (EOAT) to hold and manipulate either a tool or a piece of material.
EOAT: EOAT is itself a major area of a current technological focus, as end-users demand even greater productivity and flexibility from their robotic systems. According to an article in Control Engineering, three of the most consequential current trends include the development of safer grippers that prevent harm to human workers, EOAT connected to the Internet of Things (IoT), and the development of soft grippers that promise to expand the use of robotics in food handling applications.
Improved battery technology: Whereas lead-acid batteries have traditionally been used in material handling automation solutions, newer technologies, such as lithium-ion, are making inroads. Compared to the older technology, lithium-ion offers faster charging times, less maintenance, stable voltage with higher travel and lifting speeds. The higher cost of lithium-ion is currently a barrier to adoption for many potential users. But it seems reasonable to expect those costs to come down as the technology is adopted widely for other uses, such as electric passenger vehicles.
New automation technologies promise additional capabilities
Fact is, automated and robotic systems are getting even more and more powerful, enhanced by additional technologies such as the IoT and machine learning. In this “Fourth Industrial Revolution,” handling systems will handle not only the labor, but decision making, troubleshooting and process improvements, all without human involvement.
This is not to say that there will no longer be roles for humans in these industries. On the contrary, the worker of tomorrow will need new skill sets as he or she walks in (or logs in) to the factory or warehouse. Increasingly, these workplaces are looking for people such as technicians, software and mechanical engineers and skilled operators who can oversee this new and rapidly evolving automated machinery.
Industrial material handling is being transformed by automated machinery. Tasks — sometimes dangerous or difficult tasks — once handled by humans, are now the province of mobile or stationary machinery running off programming. Increasingly, this machinery is using sensors and other technologies to work with even greater precision and autonomy.

Traditionally dependent on fossil fuels to run key equipment, mining is known as a carbon-intensive industry. New trends, such as battery-powered underground mining equipment, are promising to disrupt that paradigm.
Increasingly, stakeholders are demanding that mining companies be more responsible and sustainable. Companies are being pressured by stockholders, workers, local communities, consumers and governments to reduce greenhouse gas emissions, reduce carbon footprints, improve air quality and protect the health and safety of workers and people living near mines. Meanwhile, others in the mining value chain — such as jewelers, electronics companies, or automakers — want assurances that the minerals they’re buying are mined responsibly.
With this as a backdrop, battery-powered underground mining equipment is starting to replace vehicles with diesel engines and equipment with electric motors is starting to replace those using hydraulics.
As stated in a 2020 article in Mining, Metallurgy & Exploration:
Though the transition to electric mining equipment has been relatively slow, it is difficult to think of the mining industry of the future still depending on fossil fuels. The shift to cleaner sources of energy is global: industries and governments across the world are implementing renewable energy source strategies and policies, regulations are becoming stricter and social scrutiny harder. Electromobility has arrived to stay and the mining industry is not excluded from its influence.
—Felipe Sánchez and Philipp Hartlieb
Download our white paper Off-Road Trends: Driving Cleaner, More Efficient and Connected Machinery, and learn what influences the advances in mobile heavy machinery.
There are other reasons why the switch to electric mining equipment makes sense for many mining operations.
One, for instance, is the competitiveness of the industry and the increasing need for miners and equipment to go ever deeper into the earth to extract more minerals. It follows that the deeper a mine, the more ventilation infrastructure is needed to help vent diesel emissions and keep workers safe. According to one estimate, up to 30% of an underground mine’s total operating costs go toward powering ventilation systems to maintain air quality.
At some point, it becomes much less cost-effective for such operations to continue using diesel ICE — even equipment that is designed to comply with current Environmental Protection Agency emission standards — in these applications.
Surface mining operations aren’t totally immune from these pressures either. Diesel-powered machines used in these operations must adhere to the same environmental regulation as construction and agricultural equipment.
Electric mining vehicle options
Many mining OEMs are taking advantage of the opportunities created by this trend. Atlas Copco® and Epiroc, for instance, offers a range of BEV, zero-emission mining machines, including the Scooptram® ST7, the Electric Boomer M2C and smaller truck models.
Sandvik® Artisan®, meanwhile, offers its Z50 mining truck, powered by lithium-ion batteries. It boasts three times more power than a diesel, and the capability to haul 50 tons of material. It also features regenerative braking and an automated battery swap system that can “refuel” the vehicle in about 10 minutes.
Challenges in the adoption of electrification
There are many challenges to the widespread shift to electrification in mining. According to a 2019 report by EY on the subject, electrification requires mining personnel to adopt some different skills, such as data and digital literacy and technical planning. In some cases, mine design needs to be rethought for better optimization of electric mining equipment.
On the engineering side, battery technology and recharging are ongoing challenges. The current industry standard is the use of large, diesel-powered generators to do the job. But as these generators are highly polluting, their use tends to defeat at least some of the purpose of the shift to electric mining vehicles. Several solutions are emerging to reduce or eliminate this reliance on diesel, including renewable energy projects at mines, hydrogen power generators for recharging and diesel generators that run more efficiently.
A cleaner, greener, safer future of mining
Mining is traditionally a very carbon-dependent industry, with heavy reliance on diesel ICE to power its equipment. That reliance may be starting to change, however, driven by pressure from stakeholders to reduce carbon footprints and protect workers and communities, along with new economic pressures derived from the need to mine farther underground. Already, major OEMs are providing electric mining equipment. As new options for charging these large batteries — including renewable resources — become more widespread, expect to see a cleaner, greener, safer future of mining.

Sewing may not be widely regarded as glamorous, but it is literally what holds the very fabric of society together. All of the clothing we wear can be found to contain neat stitching, but have you ever wondered how bulkier items like mattresses, cushions or upholstery are sewn together? The highly-sophisticated machines that make the intricate designs and quilted patterns on the surfaces of these items are very different from the simple sewing machines of yesteryear.
Although the textile industry still largely requires skilled human hands to guide and sew material, automation is steadily increasing. Now, automated stitching, quilting and embellishing for larger textiles is showcasing the possibilities for automation technology to the rest of the textile sector as a whole. Automation has a lot to offer the industry, including fast, high-volume production, excellent versatility and superior repeatability.
A long-standing partnershipNestled beneath the mountains in the town of Arth, near Lucerne, Switzerland, the factory of ASCO Bettwaren AG is highly regarded for its CNC-controlled quilting machines and services the company provides to high-end decorators and manufacturers of furniture, mattress covers and bedding. Seeing themselves as creative craftsmen eager to take on projects that others think are impossible, the ASCO team has developed increasingly sophisticated hardware, software, intuitive programming and graphical user interfaces to retain their competitive edge.
This innovation is thanks in part to the close partnership Parker developed with ASCO over the past 30 years. Parker has helped the textile specialists to develop increasingly sophisticated product offerings and designs for a wide variety of quilts, bedspreads, curtains, mattress covers, upholstery, decorative pillows and synthetic blankets.
“Our mutually beneficial partnership with Parker now extends to over 30 years, and the SNA quilting machines we currently use, including frame and QLA cross-cut machines, have proven to be solid, long-lasting and highly reliable,”
Daniel Staub, Managing Director at ASCO
The technology behind the designs
ASCO relies on Parker’s Automated Sewing Systems (SNA) for a variety of different operations, including cutting, stitching and quilting. The SNA machines offer a multitude of single-needle quilting options in a modular concept, meaning the customer can first select the best configuration for their requirements and later add to the system as needed.
The machines cut the materials to the exact size required and feed them into the sewing area, often layering together multiple layers of fabric and padding, ready to be stitched. The edges of the material are securely clamped and the needle moves continuously across the material via a moving bridge, making the desired geometric quilting patterns or bespoke designs on the textiles. All this is done by a single operator at the graphical user interface.
Behind all this technology are a number of modules and systems from Parker, including Compax3 digital servo controllers combined with SMH low inertia servo motors, HLE linear actuators, Moduflex valve islands and the P31 global air preparation system. These essential pieces of advanced motion control technology help to control the smooth movement of material by providing pneumatic clamping on the in-feed system, automatic sensing, straightening and tensioning as well as automatic cutting and unloading operations.
The latest addition to the range of SNA machines at ASCO is the SNA 4200 – a frameless, continuous sewing system with moving bridge, allowing ASCO to fully automate their quilting projects from reel to pallet. The only need for hands-on operation is ensuring the multiple material reels are ready for feeding into the machine. This makes it possible for one operator to run several machines at once, further reducing operation costs.
With a speed of up to 4,500 stitches per minute, the SNA can generate transport speeds of 23m/min during sewing (55m/min without sewing). The Windows-based software allows users to easily create or modify quilt patterns, even on the most challenging contour designs, meaning that innovative new designs can become the norm instead of the exception.

Electrification remains one of the primary trends in the automotive sector, as vehicle makers push hard to introduce cleaner technologies which result in lower emissions.
According to a recent report from global professional services company PwC, over 55% of all new car sales could be fully electrified by 2030. Cars of the future will be electrified, autonomous, shared, connected and yearly updated, it says, in what represents a new era of flexible mobility.
This trend towards electrification isn’t restricted to the passenger car market. Construction and mining vehicles, city buses and refuse trucks have all been developed with hybrid electric powertrains, as authorities look to reduce pollution by introducing more stringent environmental regulations.
But technological progression doesn’t come overnight. The shift to electrification needs to be viewed as an evolution rather than a revolution, delivered through the continued refinement of a broad range of on-board systems and components. These incremental achievements allow the industry to manufacture greener vehicles without having to compromise in areas such as performance and reliability.
A high-power density motor for traction applications
Here at Parker, our global teams of scientists and engineers are supporting these environmental efforts, designing and developing new systems that accelerate the pace of electrification. For instance, we recently extended our Global Vehicle Motor family of high-power density, permanent magnet AC motors with the GVM310, which comes with a 310mm square frame. This new product provides a traction solution for a broad range of on-road and off-road commercial electric and hybrid electric vehicles.
So, let’s look at some of the benefits that GVM310 brings to the market. Primarily, when used in conjunction with Parker’s hydraulic pumps, the GVM family helps customers realise electro-hydraulic pump solutions that allow the electrification of formerly purely hydraulic applications.
Higher performance motors for your electric or hybrid vehiclesThe high efficiency / lower energy consumption of the motor helps vehicle makers comply with stringent emerging energy legislation. It reduces CO2 footprints, is extremely quiet, and its high reliability results in reduced maintenance and downtime for operators. Options with peak power values ranging from 147 kW to 409 kW are available – with high power density meaning the size and weight of overall solutions can be minimised easing design-in for customers.
In addition to operating as a high-power motor, the GVM310 can also be run as a generator enabling effective battery management, longer duty cycles and energy savings of up to 30% compared to induction technologies. Availability as low-flux versions for high-speed applications, or high-flux derivatives for high torque applications enhances versatility.
Furthermore, the GVM family incorporates a wide range of technical features that improve performance. These include a new thinner lamination design to reduce losses, a patented cooling system and a clean, oil-free design.
The introduction of the GVM310 is an example of how Parker is providing the building blocks for electrification, developing turnkey technologies that cut time to market while reducing supply chain complexity. It offers the industry with an optimized solution for the on-road and off-road commercial electric and hybrid electric vehicles of tomorrow.
