Abstract
A vehicle electric machine assembly including a stator core, a rotor, and a bridge is provided. The stator core defines a cavity. The rotor is disposed within the cavity and may include a channel defined between two magnets. The bridge is disposed within the channel for translation between at least a first and a second position. The translation of the bridge adjusts a path of magnetic flux from the rotor to the stator core based on the bridge position. The bridge may be of a ferromagnetic material. The assembly may further include a first non-magnetic guide mounted on a first side of the channel at a substantially central channel region and a second magnetic guide mounted on a second side of the channel at the substantially central channel region.
