Abstract

See full text

A rotor assembly of a motor is configured to be rotatable relative to a stator. The rotor assembly may comprise a permanent magnet rotor segment comprising permanent magnets, the permanent magnet rotor segment configured to be rotatable by a magnetic field generated by the permanent magnets; and a reluctance rotor segment comprising flux barriers, the reluctance rotor segment configured to be rotatable by magnetic reluctance formed by the flux barriers. The permanent magnet rotor segment and the reluctance rotor segment are axially stacked relative to each other so that at least a part of a first torque ripple generated by the permanent magnet rotor segment and at least a part of a second torque ripple generated by the reluctance rotor segment can cancel each other. The permanent magnet rotor segment may be a rare earth permanent magnet rotor, and the reluctance rotor segment may be a synchronous reluctance rotor.
