UQM and Kinetics present integrated motor and multi-speed transmission for commercial EVs

UQM Technologies (NYSE: UQM) and Kinetics Drive Solutions are collaborating to offer an integrated electric motor and multi-speed transmission system for commercial vehicles.

The new system features UQM PowerPhase HD electric motors and controllers combined with Kinetics NexDrive transmissions. By providing a fully integrated and calibrated system, UQM hopes to offer customers quicker speed to market, reduced development time and cost, and fewer engineering variables.

UQM’s PowerPhase HD family of motors and controllers was developed specifically for commercial vehicle applications, and includes the HD 220 with 700 Nm of peak torque and 220 kW of peak power; the HD 950T with 950 Nm of torque and 140 kW of peak power; and the HD 250, a high-voltage variant with 250 kW of peak power and 900 Nm of torque.

Kinetics’ NexDrive EV3-850 transmission, which was developed specifically for medium- and heavy-duty EVs, is a 3-speed dual-clutch transmission that’s designed to work with the motor to minimize torque interruption during gear shifting, and to enable the motor to operate at near peak efficiency.

“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,” said UQM CEO Eric R. Ridenour. “The combined strengths of our systems, our combined marketing power and our recent ISO/TS 16949 registration will expand our reach in these important markets.”
