摘要： An automotive alternator is capable of reducing electromagnetic noises and wind noises of 12f components, which are extremely unpleasant higher harmonic noises to the ears, thereby permitting uncomfortable noises to be reduced, and also capable of suppressing a drop in output caused by a phase difference. In the alternator, two slots are applied per pole in a phase, spaces between centerlines that extend in a radial direction of openings of adjoining slots are formed to be irregular, and a first three-phase stator winding and a second three-phase stator winding are wound around a stator core with a phase difference of an electrical angle ranging from 31 to 34 degrees.

摘要： A dynamoelectric machine including first and second permanent magnets held by first and second magnet seats on first and second yoke portions so as to face inner circumferential surfaces of tip end portions of first and second claw-shaped magnetic pole portions. The first and second permanent magnets are magnetically oriented in a reverse direction to orientation of a magnetic field that the field coil produces. The dynamoelectric machine enables permanent magnet holding reliability to be increased, induced voltage during no-load de-energization to be suppressed, and thermal demagnetization of magnets due to high-frequency magnetic fields that are induced by stator slots to be avoided.
