Abstract
An actuator assembly includes an electric motor including a rotor assembly and a stator assembly configured to be actuated to cause the rotor assembly to rotate based on an amount of magnetic flux in the rotor assembly is disclosed. The assembly also includes a controllable magnetic device coupled to the rotor assembly, an actuator coupled to the rotor assembly; and a controller configured to apply electric current to the controllable magnetic device to adjust an amount of torque provided by the electric motor by adjusting the magnetic flux in the rotor assembly.
