UQM Technologies Unveils Next-Gen EV Motor Inverter


UQM Technologies Inc., a developer and manufacturer of high-efficiency electric motors, generators, power electronic controllers and fuel cell compressors for the commercial truck, bus, automotive, marine, military and industrial markets, says it will display its next-generation electric vehicle (EV) inverter at the 2016 Electric & Hybrid Vehicle Technology Expo, held on Sept. 13-15, in Novi, Mich.

According to the company, this latest technology features a motor inverter with a very compact form factor for optimized packaging, high reliability and low cost. With a volume less than 7 liters and mass less than 10 kilograms, the new motor inverter will output 600A and operate at voltages up to 550 V.

UQM says the new inverter is designed for extremely high reliability and provides 135 kW peak and 100 kW continuously to power light- and medium-duty commercial vehicles and high-performance passenger vehicles.

This technology announcement comes on the heels of the PowerPhaseDT Drivetrain partnership announcement with Eaton and Pi Innovo, which positions UQM well globally with the PowerPhase HD propulsion system paired with the Eaton 2-speed transmission and the Pi Innovo transmission control unit.

“The next-generation inverter marks another advancement for UQM as we continue to expand our reach in the commercial EV market and offer the latest technology to our customers. Our team looks forward to sharing this initial product unveiling with key customers and industry colleagues before we release it to the market as a whole,” said Adrian Schaffer, vice president of sales and business development.

Production-ready in 2018, the next generation of the UQM PowerPhasePro propulsion system will feature this new inverter paired with an updated motor and software, and the system will support the functional safety requirements needed for these modern applications.
