UQM Technologies Provides Auxiliary System Drive Motors for Use in Fuel Cell Powered Caterpillar Mining Vehicle

UQM(R) Motors to Drive Hydraulic System and Cooling Fans on Fuel Cell Powered Caterpillar Articulated Front End Loader Under Development

UQM a developer of alternative energy technologies, announced today that it has received an order from Caterpillar Inc. for UQM(R) permanent magnet motors that will be installed on a fuel cell powered Caterpillar- Elphinstone R1300 mine loader under development by a consortium of companies including Caterpillar Inc., Natural Resources Canada, and the U.S. Department of Energy, and led by Vehicle Projects LLC of Denver, CO. The UQM(R) propulsion motors include a high torque 42kW motor that will power the cooling fan and a 75kW motor that will drive the hydraulic pump. The zero emission fuel cell powered mine loader is expected to be placed in demonstration at a mine in Nevada in early 2005 to evaluate the operability, and productivity of the system.

"We are pleased that Caterpillar has selected our power dense and energy efficient permanent magnet motors to power the cooling and hydraulic systems on this exciting program. Our systems were once again selected for a demanding application where power density and efficiency are a requirement to achieve optimal system operating efficiency," said William G. Rankin, President and Chief Executive Officer of UQM Technologies, Inc.
