The recess(5) is covered with a cover(6) to form a cooling water passage. A field core(7) is installed on the inner side of the recess(5). A field coil(8) is installed on the field core(7). A stator coil(9) is installed between the outer periphery of the field coil(8) and the front and rear brackets(3,4). A stator coil(10) is wound on the stator coil(10). A cooling water passage(11) is formed in the front bracket(3) by using a connecting tube(12). A rectifier assembly(13) in which a diode is installed in a disc-shaped cover(6) of the rear bracket(4). A voltage regulator(15) is installed on one side of the rectifier assembly(13).
