 Looking for efficiency and reliability as well as peak power for on-highway and off-highway vehicles, both electric and hybrid? Comparison analysis and 135 million road miles logged has shown that the Parker GVM310 is a powerful choice for both types of vehicles, engineered for traction and electro-hydraulic pumps (EHP) up to 409 kW peak power. Check out the infographic for more of the results.

High power Permanent Magnet AC motors (PMAC) offer the best solution to meet the requirements of vehicle duty performance. With a ten year legacy and thousands of units sold, the high power density and speed capabilities of Parker GVM motors combined with a voltage matched inverter provide the speed and torque required to achieve breakthrough performance in a variety of vehicle platforms.

In addition to operating as a high-power motor, the GVM310 is a very high-efficiency generator enabling energy savings of up to 30% compared to induction technologies. The GVM family achieves high power density thanks to a patented liquid cooling system, which also results in a cleaner, less complex, oil-free design. Moreover, to ensure reliability and long life under tough conditions, the GVM motors have been put through a battery of validation tests.

Look at the numbers

 Up to 2% more efficient than competitive motors. Efficiency is the motor's capability to produce useful mechanical power efficiently. A more efficient motor reduces the cost to operate, runs cooler, and is better for the environment. Parker's higher efficiency GVM means a cost reduction of the vehicle battery in a longer range between charges. 


 From 40% to 100% more peak power than competitive motors. Power density refers to the amount of power produced relative to the physical size of the motor. The high power density of the GVM saves on installation costs when compared to oil-cooled motors.  Enhanced power density with up to a 200% smaller footprint.


Durability and reliability are characteristics of the GVM that make it suitable for rough environments. Test standards meet SAE J1455 for dust, sand, gravel bombardment, humidity, salt spray, and immersion, operating temps from -40° to 120°C, crash shock, and vibration. 


Engineered for traction and electro-hydraulic pumps (EHP)

The GVM motor line has been designed to be used in a wide variety of construction vehicle applications. A variety of available magnetic options allow for a wide range of voltage, speed, and torque requirements. The GVM family achieves high power density thanks to a patented liquid cooling system, which also results in a cleaner, less complex, oil-free design. The GVM310 is an example of how Parker is providing the building blocks for vehicle electrification, developing turnkey technologies that cut time to market while reducing supply chain complexity.
