Abstract

An alternator for use in an automobile includes brackets for supporting a rotation shaft at both sides of a rotor, being thermally connected to a stator for supporting the stator, while one side of the rotor is closed by a bracket. A cooling water passage is provided in the bracket, a cooling fan is provided on the closed side of the rotor, and a cooling fin provided opposing to the cooling fan and in vicinity of the cooling water passage, thereby enabling cool down of the stator and the rotor, effectively, with low noises, and thereby obtaining a high power output.
