UQM Technologies Inc. is collaborating with BorgWarner on electric powertrain products for all-electric and hybrid-electric passenger automobiles. Initially, the companies are working together to integrate UQM Technologies’ PowerPhase electric propulsion system with BorgWarner’s 31-03 eGearDrive transmission for the all-electric Coda, a China-built front-wheel drive five-passenger sedan marketed by Miles EV and scheduled for introduction in the California market in mid-2010. The PowerPhase electric propulsion system has a peak power rating of 100 kW and a continuous power rating of 45 kW. It delivers peak torque of 300 N•m (221 lb•ft) and continuous torque of 160 N•m (118 lb•ft). With a diameter of 280 mm (11 in) and a mass of 46 kg (102 lb), this motor fits in a range of passenger vehicles, including subcompacts. The 31-03 eGearDrive transmission is suited for midrange electric vehicles on either front-wheel-drive or rear-wheel-drive transverse driveline applications. The single-speed 31-03 uses a unique flange and coupling for adaptation to the PowerPhase motor housing to accommodate input shaft speeds of up to 14,000 rpm with a range of reduction ratios and very high operating efficiency.
