Permanent magnets solidified from liquid magnetic material are disposed in the cavities to form poles of the rotor with at least a portion of the cavities having directly abutting permanent magnets comprised of at least first and second magnetic materials of different properties injected in liquid or mobile form into single cavities. In interface regions between the at least first and second magnetic materials the first and second magnetic materials are intermingled to form a transition zone.
