PURPOSE:To miniaturize and lighten it by forming one part of the casing of a motor out of the stator core, which has stator winding, of a DC brushless motor, and equipping it with heat radiating fins so as to improve heat radiation effect. CONSTITUTION:A stator 4 is held between the front cover 2 and the rear cover 6, to which bearings 5 and 7 for bearing the rotary shaft 9 of a rotor 8 freely in rotation are attached, and one part of the casing 1 of a motor is constituted. The stator 4 has stator winding 3, and is formed of the heat radiation plates 20 consisting of aluminum plates interposed between a plurality of circular cores 4b stacked in a multilayer shape. |
