ABSTRACT:
A magnet seat is disposed on a second yoke portion and projects into respective spaces between circumferentially-adjacent pairs of second claw-shaped magnetic pole portions, and permanent magnets are disposed only near the second yoke portion so as to be held by the magnet seat so as to face an inner circumferential surface near a tip end of each of a plurality of first claw-shaped magnetic pole portions. Each of the permanent magnets is magnetically oriented in a reverse direction to an orientation of a magnetic field that a field coil produces.
