Patent ID: 10312783

Abstract:
An electric machine assembly for an electrified vehicle including a stator core, a rotor, a first pair of magnets, a second pair of magnets, and a variable flux magnet is provided. The stator core defines a cavity. The rotor is disposed within the cavity for rotation and includes a bridge. Each of the first pair of magnets may be mounted to the rotor and spaced from one another on either side of a first D-axis. Each of the second pair of magnets may be mounted to the rotor and spaced from one another on either side of a second D-axis. The first D-axis and the second D-axis are spaced from one another on either side of a Q-axis. The variable flux magnet is embedded in the bridge and located on the rotor to influence current associated with the Q-axis to control torque output of the rotor, and to pulse D-axis current to control a magnetization of the bridge.
