ABSTRACT:
A permanent magnet rotor for an electric motor may include a rotor assembly that will hold the magnets in place. A pair of rings is added to the sleeve to tightly engage and press against the end plates and the magnets. This configuration provides additional securement against axial and radially shifting of the magnets.
