A dynamoelectric machine in which the stator has permanent magnet poles composed of a soft magnetic material. The sides of each magnet pole have rare earth magnets around and in contact with their outer extremities. The surfaces of these rare earth magnets in contact with the magnet poles have the same polarity as the surface of the magnet poles which they contact. The rare earth magnets serve to reduce stray magnetic flux and thereby concentrate the magnetic flux in the air gap between the stator and the rotor.
