Many industries are now being required to drastically reduce carbon emissions as a consequence of rising global temperatures, and the automotive industry in particular is a focus of much regulatory pressure.

Fundamental to the need for original equipment manufacturers to meet the rigorous safety requirements of an entirely new generation of electric vehicles is the ability to implement repeatable quality testing using the most advanced technology in test rigs.

The Electric Vehicle (EV) market now needs specially-adapted high-speed motors for test benches that will offer sufficient speed, power and acceleration to meet the tough qualification process for electric engines, pumps and powertrain transmissions. Over the past few years, Parker has received numerous requests for test rig motor speeds above 22,000 rpm, with torque levels above 400 Nm and high dynamic performance. This has led Parker to develop a new high-speed MGVA motor to extend the MGV series of brushless synchronous servomotors with, which features water cooling and electromagnetic optimisation to offer increased service lifetimes, reduced maintenance and optimum performance to meet market expectations.

Typically, any high-speed application will require a specialist integrator who will design the test rig system, looking for the right combination of products that will endure the rigours of the test campaign. This expert will need to decide on all the various mechanical factors of the system, such as ensuring the correct dimensions and rigidity of the test bench chassis to avoid resonance-relation vibration, choosing the best type of coupling according to the line shaft, speed, torque and acceleration, and ensuring that the temperature is controlled to avoid failure.

After this is complete, the specialist integrator will need to find an appropriate drive solution for controlling the MVGA servomotor, such as the Parker A30 drive. Above nominal speeds, the permanent magnet AC motor will need to be controlled under a ‘field weakening’ mode to protect the rig from overvoltage in case the power supply goes down.

A turnkey cabinet will then need to be built to enclose the rig. The cabinet should provide overvoltage protection and a four-quadrant active front end (AFE) solution if necessary, depending on the particulars of the test cycle. To complete the project, a water chiller is then installed for precision cooling.

Parker can provide custom solutions tailored to meet even the most challenging technical specifications. The expertise of our technology-focused engineering team allows the OEM to decide how much or how little support they need. Parker’s extensive portfolio, which includes motors, drives, controllers, HMIs, actuators and gearheads ensure the right combination of application-compatible products will be selected every time.

The high-speed electric vehicle test bench plays a vital role towards ensuring the safety and performance of vehicle electrification, which in turn will allow us all to enjoy cleaner air free of fine particles in the future.

Data acquisition in the modern, digitally-driven production environment can result in better product quality management than ever before.

The ability to collect, evaluate and react to data in real-time is the basis for excellent oversight of production processes to highlight problems and deviations. Anomalies can be quickly addressed, guaranteeing product quality without causing downtime or delays.

The efforts to use data as a means of improving products quality have been given a significant boost by the launch of a new Parker solution for press and joining applications. Push-To-Fit is an innovative electromechanical kit combining a process control unit, servo drive, motor and electro cylinder connected through software into a joining module - that can be quickly integrated into general industrial and automotive assembly lines.

The hub of the solution is a process control unit that provides simple parametrization, visualization and operation. The monitoring method used ensures that real-time quality control is guaranteed, with the process control unit fully compatible with, and prepared for, third-party device connectivity with dual LAN networks and options for Profinet, Ethernet IP and Modbus. Numerous operating options such as web visualisation, digital I/Os and communications interfaces, e.g. OPC UA are available to facilitate integration.

Ease-of-use is boosted through real-time control information, historical/trend data, adjustable error response, definable motion profiles, and monitoring via tolerance windows or tolerance curves. Measured values and complete curves are provided in real time and permanently saved to a database. The creation of such valuable data allows immediate intervention and correction in case of deviations via any HMI with a web browser. The production management system can then take care of automatically generating an error notification message which can be sent SMS or by email to the relevant member of the production team.

The availability of long-term data for each production cycle can also be used as a means of proving product quality - even several years after production has taken place.

The IPM protocol in the Push-To-Fit system provides the Integrated Process Data Management Software with data for each production cycle, automatically recording physical process and measurement information. This data can be accessed at any time, perhaps as a means of responding to any legal provisions or supporting internal requirements.

The IPM Process Data Management Software and the IPM protocol are products of the company CSP GmbH & Co. KG, Germany.

Many of these characteristics - instant quality assessment, fast error logging, automatic notification and integrated archiving – can act as potent drivers of product quality inside a modern production facility. The collection of meaningful data can also provide benefits in other areas, such as helping to reduce product recalls and eliminating any unnecessary and costly downtime.

Push-To-Fit is, therefore, a welcome addition to the Parker range of electromechanical solutions. Visit our product page to learn more about the advantages it can bring to your industrial assembly projects.

Industry 4.0 – considerations for machine builders selecting motion control products

Motors and sensors go hand in hand. The EX range of motors already feature a wide range of sensors that deliver feedback on various parameters and, now, Parker has added a HIPERFACE DSL® encoder to the EX range of motors with explosion-proof enclosures. This makes it even simpler to control and monitor the EX servo motors using a Parker Servo Drive controller.

The High Performance Interface Digital Servo Link protocol runs on a standard RS485 connection to add the level of robustness needed to use it in almost any application. This includes industrial machinery, robotics and chemical and waste processing plants.

The main benefit of this technology is that it uses just one cable to deliver all of the motor control functions. This cable, which can be up to 100m long, can be bundled with the power cable, making it simpler to provide power and control to machines, robots and other equipment. With just one, smaller cable required, the umbilical for industrial machinery is lighter and more flexible, making them more reliable while delivering greater freedom of movement.

The EX motors, now equipped with the HIPERFACE DSL® interface, feature an explosion-proof enclosure and are certified for use in explosive atmospheres (CE/ATEX and IECEx). This includes use in atmospheres where explosive gases or dust are present.

As only one cable is needed, the EX motors have a lower total cost and provide a more reliable solution than a motor that requires two connections for control and feedback. These permanent magnet motors have a torque range of 1.75 to 35 Nm and come with a 2-pole resolver as standard and now an optional HIPERFACE DSL® encoder. This offers up to 20 bit resolution per revolution and a maximum of 4,096 revolutions in a multiturn system. Thermal protection is covered by the thermoswitches and thermofuses that are integrated into the motor's windings.

EX motors are compatible with the Parker Servo Drive (PSD) series, providing a complete solution for motor control in ATEX applications.

We can also offer a complete drive solution for ATEX applications with ETH the actuator and GXA gearbox (ATEX).

Finally, Parker’s well-known ETH electro cylinder range for explosive atmosphere is certified for use in explosive gas atmospheres (device group II, category 2G).

The advent of the smartphone and tablet has had a dramatic impact on the types of media we consume. Whereas in the past we might have been wedded to printed sources such as newspapers or magazines, the ubiquitous nature of electronic devices means video has emerged as a highly popular visual means of accessing information and entertainment.

Video perfectly suits the hectic pace of modern life. A tightly edited and well-produced video can be informative, engaging and easy to digest - even on the go - making that this type of format a good match for today’s always-on, 24/7 society.

It comes as no surprise, therefore, to find that video has become an increasingly popular form of media in B2B markets. Many industrial organisations are now in-step with their tech-savvy customers, creating high-quality videos that encapsulate the technical capabilities of the systems and components they produce. Indeed, according to recent research (video marketing statistics 2020 by Wyzowl), 85% of businesses now use video as a marketing tool, proving what a convenient and accessible medium it has become. 

Maintenance is particularly suited to this type of format. It is often easier to show how to prevent or fix a problem than it is to explain in a wordy repair manual. That’s why most companies have established YouTube channels as valuable knowledge resources for technicians and engineers responsible for maintaining equipment, both in plants and out in the field.

Here at Parker, video has been used to provide maintenance support for the new HLR range of electromechanical linear actuators. These three-minute productions cover a broad range of topics including ‘How to re-lubricate an HLR actuator’, ‘How to re-tension the HLR toothed belt’ and ‘How to replace the HLR steel strip cover’. 

They also detail the assembly of the HLR within an application, covering areas such as ‘How to mount a gearbox to an HLR’, and ‘How to set up an HLR two axes configuration’. In each case, the videos have been made to get technical information across in a clear and concise manner that supports the more productive working of the maintenance professional. 

Going forward, Parker is committed to using video as a means of talking to our customers. That doesn’t mean the end of the printed word in technical manuals: it is about using the power of technology to complement more traditional types of media to communicate in the most effective way that we can.

Parker’s Electromechanical and Drives Division offers specific tutorials to facilitate maintenance and improve the user experience. The video channel, has been enhanced with five new videos relating to the HLR range to help maintenance professionals carry out common operations.

Visit Parker EMDE YouTube support to see the various tutorials already online. You can see here the most popular HLR electromechanical linear actuators maintenance video.

Practical Applications for Precision Electromechanics in Photonics

Broadly speaking, it is the automatic safety function that either ensures that the intended function is performed correctly or where this is not possible, ensures that the system will shut down in an orderly, and therefore safe, way. Functional safety is governed by two main industry standards addressing the safety lifecycle and the different types of failures from faults: IEC61508 and IEC61511.

For machine designers, it’s clear that following the Machinery Directive is not just about simply buying components that offer safety certification. Comprehensive hazard and risk assessments must first be carried out to ensure not just the operator’s safety but also ease of use. Once the design process is complete, technical safety measures can be implemented, such as placing guards around the machine and selecting components that offer excellent functional safety features.

Process shutdown in motion control machinery such as servo motors and drives are becoming increasingly important, particularly for critical elements such as brakes on vertical axes. Ensuring that the stopping reaction time is fast enough to protect body parts from the force of the motion is essential, and this needs to be tested very regularly.

Shutdown systems must be additionally responsive and flexible in applications such as packaging and production machinery which require a high extent of machine safety. Functional safety components can be connected via safety input-output (I/O) or other proprietary bus systems, but the most advanced solutions are based on safety fieldbuses which are flexible and powerful.

Parker now offers an advanced PSD line of products with Functional Safety over EtherCAT (FSoE), providing a complete, centralised functional safety solution that requires no additional wiring.

A powerful, freely-programmable FSoE master, the Parker Safety PLC, addresses all safety components via the network such as safety inputs and outputs as well as PSD drive controllers with integrated safety technology. External components such as light curtains, emergency buttons and safety shut-off mats are connected through the safe I/O-Modules.

When functional safety is done correctly, the operator is not constrained in any way and should have no reason to avoid any safety devices. Similarly, machine uptime will not be negatively impacted due to safety techniques, ensuring smooth and efficient operations on the processing line.

Overall, the benefits of using servo drives with integrated safety functionality are hard to ignore; such as a reduction in wiring and components, ease of use and increased productivity. Functional safety also has much to offer Industry 4.0. Not only is safety going to become increasingly important in automated factories where there will need to be a greater level of trust between machines and humans, but safety systems will also improve diagnostics, efficiency and reliability.

To discover all the safety features offered by the PSD drive watch the animation.

Understanding the Machinery Directive

In a hospital or clinical environment, personal protective equipment (PPE) is important and necessary to decrease staff and patient exposure to airborne ailments. Unfortunately, custom equipment may not be available on short notice. On the other hand, T-slot aluminum framing, best known for modular workstations, machine guarding, and tables, is configurable and can lend itself to any type of structure such as protective shielding and screening equipment. Parker IPS T-slot framing is readily available from authorized Design Centers and distributors, with all the accessory panels and parts to make your healthcare-related design a reality.

With a growing need for thousands of portable respirators and other emergency equipment such as defibrillators to be used by healthcare providers in the fight against COVID-19, Parker has designed modular rolling carts to be built using IPS t-slot aluminum profile and standard accessories. These carts can easily be used in hospitals, emergency rooms or any temporary medical facilities treating patients with COVID-19. The finished assembly is easily cleaned.

Constructed from light but strong aluminum extrusion material, this partition features a lightweight profile and a polycarbonate panel to protect neighboring beds in the room. It is approximately 6 feet by 4 feet and is equipped with adjustable leveling feet for stability. Alternatively, it can be fitted with casters for ease of portability. The durable polycarbonate panels are easily spray-cleaned, for a comfortable environment for patients and staff alike.

For use when intubating patients with Coronavirus, this prototype shield is constructed from 20 x 20 aluminum profile. The design is modular and easy to assemble on site. The top polycarbonate panel is attached to the extrusion, and the three framed panels are attached to a straight plate. One panel features pre-cut holes for patient intubation. The assembled shield is easy to clean as needed.

This free-standing 12’ x 12’ room is made from 40x40 light aluminum IPS profile and 9 white opaque PVC panels that are pre-assembled. Each panel is approximately 4’ x 7’. The front opening can be closed for privacy with two 84” x 84” hospital cubicle curtains that slide on the extrusion track. The finished assembly is easily cleaned. Either standard slotted profile or the smooth face style may be used

12’ x 12’ hospital room modules can be ordered in multiple quantities to be assembled in tandem. Constructed of 40x40 light aluminum IPS profile, they are easy to assemble on site since the 9 white opaque PVC panels are shipped pre-assembled. Front opening for each room can be closed with two 84” x 84” hospital cubicle curtains that slide on the extrusion track. The finished assembly is easily cleaned. Either standard slotted profile or the smooth face style may be used.

With these examples in mind, we would like to help make your process from concept to completed structure quick and efficient. When you have your initial idea for building with t-slot framing, how do you convey the concept? Do you use a piece of paper, CAD or even the famous napkin to sketch out your thoughts?

Traditionally, and still today, the “napkin sketch” method is how most t-slot aluminum framing companies encourage the user to send in information. It is very effective and allows the customer to quickly convey their ideas. But with the right software, customers can use electronic tools to create their designs.

Imagine a tool that gave you template libraries that can be downloaded from the web and all the parts and components available to build a design, with the capability to export files into various 3D CAD formats. That’s Parker TADA (T-slot Aluminum Design Architect) and it’s available now as a free download.
