Abstract
In one embodiment, an apparatus includes a rotor shaft, at least one pole segment, at least one pole tip segment and at least one permanent magnet pair. The at least one pole segment is mechanically coupled to the rotor shaft. Each permanent magnet pair is disposed between the at least one pole segment and respective pole tip segment. The apparatus further includes at least one mechanical member that mechanically restrains the at least one pole tip segment to at least one of the rotor shaft or the at least one pole segment.
