September 4, 2009 – Vol.14 No.24 UQM and BorgWarner Team on Electric Drive. UQM Technologies has announce that it is collaborating with BorgWarner electric powertrain products for all-electric and hybrid-electric passenger automobiles. Initially, the companies are working together to integrate UQM Technologies’ PowerPhase(R) electric propulsion system with BorgWarner’s 31-03 eGearDrive(tm) transmission for the all-electric CODA front-wheel drive five-passenger sedan, scheduled for introduction in the California market in mid-2010. Delivering nearly 2,000 Nm (1,500 ft-lbs) of torque with a gear ratio of approximately 6.5 to 1. The UQM/BorgWarner package will propel a mid-size passenger vehicle at highway speeds with economical, high powertrain efficiency. The UQM PowerPhase electric propulsion system has a peak power rating of 100 kW (134 horsepower) and a continuous power rating of 45 kW (60 horsepower). It delivers peak torque of 300 Nm (221 ft-lbs) and continuous torque of 160 Nm (118 ft-lbs). With a diameter of only 280 mm (11 inches) and a weight of 46 kg (102 lbs), this motor will fit easily in a wide range of passenger vehicles, including subcompacts. The system also features optimized four-quadrant performance, dynamic torque, speed and voltage control, and system energy efficiency of over 90 percent across a substantial portion of its power curve. The BorgWarner 31-03 eGearDrive transmission is ideally suited for mid-range 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 PowerPhaseĈ motor housing to accommodate input shaft speeds of up to 14,000 rpm with a wide range of reduction ratios and very high operating efficiency. The 31-03 is also available with an optional ePark feature, an electronically actuated park lock system.
