Abstract

PURPOSE:To sufficiently cool a stator power generating coil on the opening side of the cup-formed fly-wheel of a rotor, by arranging projections on the surface opposite to the magnet contact surface of a magnet fixing member. CONSTITUTION:On the surface which is not confronted with the surface of a magnet 5, of a magnet fixing member 15 on the opening side of a cup-formed fly-wheel 4, a plurality of projections 13a are arranged. The projections 13a are radially arranged in the direction of the radius of a rotor 1. In this case, when the rotor 1 is rotated, then the fly-wheel 4 and magnet fixing members 12, 13 are also rotated, and a stator power generating coil 8b on the opening side of the cupformed fly-wheel 4 is cooled because of the flow of air generated by the projections 13a of the rotating magnet-fixing member 13.
