ABSTRACT:
An electrical machine includes both a permanent magnet source of field excitation and an electromagnetic source of field excitation. The electrical machine also includes a homopolar rotor, which carries the permanent magnet source, and a lamination stack having a middle portion and outer portions. The homopolar rotor and the middle portion of the lamination stack conduct flux generated by the permanent magnet source. The homopolar rotor and the outer portions of the lamination stack conduct flux generated by the electromagnetic source when the electromagnetic source is energized.
