GM shows 85 kW permanent magnet EV motor
General Motors will become the first American automotive manufacturer to build its own electric motors when production begins in White Marsh, Md., in late 2012. In promoting this capability, GM has released details of the first motor to be built there, the 85 kW (114 hp) permanent magnet motor to be used in the 2013 Chevrolet Spark EV.
Currently, GM uses electric motors as part of the propulsion system in nine vehicles including the Chevrolet Volt, Chevrolet Malibu Eco, Chevrolet Silverado Hybrid, Buick Lacrosse eAssist, Buick Regal eAssist, GMC Sierra Hybrid, GMC Yukon and Yukon Denali Hybrid, and Cadillac Escalade Hybrid.
GM is focused on the development of permanent magnet and induction motors for a variety of applications, and the White Marsh facility will produce such motors for the Spark and other, as-yet-unnamed future vehicles.
