A pair of magnetic pole cores mounted on the rotor has end surfaces and holds an exciting coil theirbetween. Two fans are mounted on the end surfaces, respectively, so as to produce cooling blow. wherein said magnetic pole cores are formed such that a height in a circumference direction thereof is greater than a length between said two surfaces to thereby increase an area thereof to be in contact with said exciting coil, so that the transfer and diffusion of the heat of the exciting coil to the magnetic pole can be performed.
