ABSTRACT:
A permanent magnet rotor for high speed motors and generators is constructed to minimize tensile stress on the magnet material by preloading the material with a radially inward compressive force. In the two-pole configuration, this force is provided by wedges inserted into a dovetail connection between a pole piece and a nonmagnetic support structure. In a configuration having four or more poles, drive wedges are inserted between a magnetic pole piece and a retaining wedge to produce a compressive force on bar magnets which produce a circumferentially oriented magnetic field.
