摘要： A three-phase alternating-current winding is constructed by forming winding phase portions into a Y connection. The winding phase portions are divided into first and second winding divisions. Outputs from the first winding divisions are rectified and output by a first rectifier, and outputs from the second winding divisions are rectified and output by a second rectifier. In addition, a magnetizing electric current supplied to a field winding is adjusted by a voltage regulator such that the output from the second rectifier becomes constant.

摘要： 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 at its extreme end on an inclined inside surface. The magnet mounting member carrying the magnets in the magnet retaining portions is mounted on each claw-shaped magnetic pole with the middle portion of the magnet mounting member situated against the inclined inside surface of the magnetic pole, and a backup ring is fitted inside the magnet mounting members.
