UQM Technologies Inc. and Kinetics Drive Solutions Inc. are collaborating to offer an integrated electric motor and multi-speed transmission system for commercial vehicle applications that will benefit from a full system approach. This system is engineered to provide commercial vehicle manufacturers with an efficient electric drive powertrain while minimizing the development time for integration.
Advantages for customers will be a fully integrated and calibrated system that allows quicker time to market and reduced development time and cost, as well as fewer engineering variables. Systems will feature UQM PowerPhase HD electric motors and controllers combined with Kinetics NexDrive transmissions.
As we work with multiple partners in China and other regions of the world, it has become clear that for some the ability to offer a complete system will be a competitive advantage. By collaborating with Kinetics we are able to offer those customers a proven powertrain system.—Eric R. Ridenour, President and CEO of UQM
The PowerPhase HD family was developed specifically for commercial vehicle applications, and includes high performance liquid cooled permanent magnet motors and high-power, liquid-cooled inverters with full-featured digital signal processor controllers.
The lineup includes the HD 220 with 700 N·m (516 lb-ft) of peak torque and 220 kW of peak power; the HD 950T with 950 N·m (701 lb-ft) of peak torque and 140 kW of peak power; and the HD 250 which is a high-voltage variant with 250 kW of peak power and 900 N·m (664 lb-ft) of peak torque.

|Continuous power||120 kW||150 kW||100 kW|
|Peak power||220 kW||250 kW||140 kW|
|Full power voltage||370 - 450 VDC||450 - 750 VDC||370- 450 VDC|
The NexDrive EV3-850 transmission is a 3-speed (gear ratios 3.58, 1.86 and 1.00:1) dual-clutch transmission that efficiently works with the electric motor to minimize torque interruption during gear shifting. It also enables the electric motor to operate at peak or near peak efficiency for improved battery performance and vehicle range.
Kinetics designed and developed the EV3-850 specifically for medium- and heavy-duty electric vehicle applications.
