Abstract
A rotor assembly for an electric motor includes a rotor core that is fabricated from a plurality of stacked laminations. The rotor core has a plurality of arcuately arranged, axially extending magnet receiving slots. The rotor core includes a plurality of magnets received in respective ones of the magnet receiving slots. The laminations include radially extending deflectable magnet retaining tabs that extend into the magnet receiving slots. The magnet retaining tabs engage and are deflected by a corresponding one of the magnets to exert a reactive force against the magnets.
