Abstract
An internal permanent magnet machine includes a wound stator, and a rotor core. The rotor core includes a plurality of first pole cavities, and a plurality of second pole cavities. One of a plurality of magnets is disposed within each of the pole cavities, and is injection molded into their respective cavity. The first pole cavities and the second pole cavities are each arranged in a pre-defined configuration, such that each pole cavity of the first pole cavities is identically positioned with one of the pole cavities of the second pole cavities within their respective pre-defined configurations, to define a corresponding pair of pole cavities. The pole cavity of the first pole cavities and the pole cavity of the second pole cavities of at least one of the corresponding pair of pole cavities define a different shape relative to each other.
