Abstract
A propulsion system for a vehicle includes an electric motor configured to generate torque to propel the vehicle. The electric motor has a stator assembly with a plurality of stator slots defining slot layers along a respective slot axis. A first plurality of conductors is at least partially positioned in the plurality of stator slots and forming a first winding set. A second plurality of conductors is at least partially positioned in the plurality of stator slots and forms a second winding set. A first inverter is adapted to drive the electric motor, the first winding set being coupled to the first inverter. A second inverter is adapted to drive the electric motor, the second winding set being coupled to the second inverter. The system includes a controller adapted to control operation of the first and second inverters based in part on a motor speed of the electric motor.
