Abstract
Deformation and vibration of claw magnetic poles in rotor are reduced. A rotor includes: a rotor coilfor generating a magnetic flux by applying a current; a pole core comprised of a first pole core bodyand a second pole core bodythat are disposed so as to cover the rotor coil, each being provided with claw-shaped claw magnetic polesengaging with each other; and a magnet assemblycomposed of a magnetfor reducing leakage of magnetic flux and a magnet-holding memberfor supporting the magneton the claw magnetic poles. Center of gravityG of the magnet assemblyis located on the base part side nearer than the center of the claw magnetic poles
