EVS-23: UQM 25 KW Generator

04.12.2007 (wattgehtab.com) - Colorado - UQM Technologies announced that its compact and lightweight 25 kW generator and its recently introduced 150 kW propulsion system will be showcased at EVS-23, the world´s largest symposium and exhibition for electric, hybrid electric, plug-in hybrid electric and fuel cell vehicles, on December 2nd through 5th in Anaheim California.

The 25 kW UQM liquid-cooled generator, which is a compact 186 millimeters (7.3 inches) in diameter by 200 millimeters (7.75 inches) in length, weighs a meager 22 kilograms (49 pounds) and operates at 340 volts DC with a narrow plus or minus 2 volt DC regulation tolerance at operating speeds of 4,000 to 6,500 r.p.m. The generator is designed to be gear driven from an internal combustion engine and has a maximum speed rating of 11,000 r.p.m. The generator and its advanced CAN compatible liquid-cooled control electronics will be on display in booth number 776 at the exhibition.

On December 5th at 8:30 a.m., Jon Lutz, Vice President of Technology, will make a presentation during an auditorium session of the symposium on the Company´s recently introduced 150 kW (201 horsepower) peak power permanent magnet electric propulsion system. The propulsion system has a continuous power rating of 100 kW (134 horsepower), delivers peak torque of 650 N-m (480 ft-lbs) and continuous torque of 400 N-m (295 ft-lbs) and has the highest power density of any of our 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 percent over substantially all of its performance regime.
