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.

摘要： A method of controlling an electric rotating machine for a vehicle includes an electric rotating machine (1) including a rotator having a field winding (5) and a stator having an armature winding (3), a field current controller (9) for controlling a field current supplied from a direct-current power supply to the field winding (5), and a power converter (6) for converting a direct-current power into an alternating-current power and applying the power to the armature winding (3). When the field current controller (9) starts to supply a current to the field winding (5) for starting an internal combustion engine, the power converter (6) supplies a power to the armature winding (3) so that magnetic flux in a direction opposite to that generated by the field winding (5) is generated simultaneously with or immediately before starting the power supply.
