Abstract:
A dynamoelectric machine includes first and second magnet seat portions disposed to project from portions of first and second yoke portions that face respective inner circumferential surfaces near tip ends of second and first claw-shaped magnetic pole portions, and magnet housing portions disposed integrally to extend axially outward from outer circumferential portions of a pair of flange portions of a bobbin, extend near the first and second yoke portions that face the inner circumferential surfaces near the tip ends of the first and second claw-shaped magnetic pole portions, and be held by the first and second magnet seat portions. First and second permanent magnets are housed and held in the first and second magnet housing portions, are disposed to face the inner circumferential surfaces near the tip ends of the second and first claw-shaped magnetic pole portions, and the first and second permanent magnets are respectively magnetically oriented in a reverse direction to a direction of a magnetic field that the field coil produces.
