ABSTRACT:
Pole core members of a rotor are fitted on a rotary shaft with claw-shaped magnetic poles engaged with one another from front and rear sides. Each of magnet mounting members for holding magnets against side surfaces of each magnetic pole has magnet retaining portions on both sides and a platelike middle portion. Located between two adjacent claw-shaped magnetic poles, each magnet produces a magnetic field oriented in a direction opposite to the direction of a magnetic flux formed between the adjacent claw-shaped magnetic poles. The claw-shaped magnetic pole has a stopper portion protruding inward from an extreme end of the magnetic pole on an inclined inside surface thereof. The magnet mounting member carrying the magnets in the magnet retaining portions is affixed to each claw-shaped magnetic pole with the middle portion of the magnet mounting member fitted in a recess formed in the inclined inside surface of the magnetic pole.
