ABSTRACT:
Deformation and vibration of claw magnetic poles in rotor are reduced. A rotor includes: a rotor coil15for generating a magnetic flux by applying a current; a pole core comprised of a first pole core body19and a second pole core body20that are disposed so as to cover the rotor coil15, each being provided with claw-shaped claw magnetic poles21, 22engaging with each other; and a magnet assembly25composed of a magnet23for reducing leakage of magnetic flux and a magnet-holding member 24 for supporting the magnet23on the claw magnetic poles21, 22. Center of gravity25G of the magnet assembly25is located on the base part side nearer than the center of the claw magnetic poles21, 22.
