Abstract
An electric motor assembly includes a stator having a first set of electrical windings. The motor assembly includes a rotor assembly rotatable about an axis of rotation and that has a rotor with first and second rotor segments. Each of the rotor segments has a respective set of magnets spaced therearound. The motor assembly has a phaser that includes a phaser actuator and a phaser gear mechanism. The phaser gear mechanism has a plurality of members. The phaser actuator and the first and second rotor segments are each operatively connected to a different respective one of the members. The phaser actuator is activatable to change an angular position of the member to which the phaser actuator is operatively connected, moving one of the rotor segments about the axis of rotation relative to the other of the rotor segments to reduce back electromotive force in the first set of stator windings.
