A switched reluctance motor includes a stator, a rotor, and a planetary gear assembly. The rotor defines an internal cavity that houses the planetary gear assembly. The switched reluctance motor receives input and provides output through a common single shaft. The shaft is part of a vehicle driveline and can be positioned to provide driving input to a transmission or drive axle, for example. The planetary gear assembly includes a planet carrier that is fixed for rotation with the shaft and a sun gear that is coupled to the rotor. The planetary gear assembly allows the rotor to rotate at a higher speed than the shaft such that the switched reluctance motor can operate more efficiently for low speed vehicle applications.
