UQM Introduces New 150 kW Drive System
19 June 2007
UQM has developed and is taking orders for a new 150 kW (200 hp) peak power proprietary permanent magnet propulsion system. The new propulsion system is suitable for high performance automotive applications and heavy-duty commercial and military vehicles.
The propulsion system has a continuous power rating of 100 kW (143 hp), delivers peak torque of 650 Nm (480 ft-lb) and continuous torque of 400 Nm (295 ft-lb) and has the highest power density of any of its propulsion systems. The system also features optimized four-quadrant performance, on-the-fly torque, speed and voltage control and system energy efficiency of over 90% over substantially all of its performance regime.
This system will allow us to pursue additional market opportunities for those vehicle platforms with higher power requirements that we were previously unable to service.—Jon Lutz, Director of Engineering
UQM recently was awarded an additional $750,000 Phase II Small Business Innovation Research contract from the US Air Force to advance the development of a silicon carbide (SiC) electronic motor controller. Coincident with that project, UQM is converting a conventional pickup truck to all-electric operation using a motor controller containing the higher power silicon carbide modules that are being developed.

Earlier in the year, UQM formed a strategic alliance with lithium-ion battery maker Altairnano to pursue opportunities for their complementary electric drive and battery technologies in advanced transportation and other high potential markets. (Earlier post.)
UQM and Altairnano are working with Phoenix Motorcars on the development and launch of the all-electric sport utility truck (SUT). The Phoenix all-electric SUT is powered by a 100 kW UQM electric propulsion system which produces more than 400 lb-ft (542 Nm) of torque.
