Abstract

PURPOSE:To discharge heat effectively, by molding resin in a state that a cooling fin is fitted to a component of large heat generation among driving circuit components, and by composing said cooling fin so that it may be abutted on a bracket for bearing a rotor. CONSTITUTION:A printed board 4 fitted on a core insulation layer 2 is provided with a sensor 6 inserted into a sensor fixing stand 5 formed to set the pitch of the electrical angle of 120 deg., a motor driving IC 7, and a cooling fan 8 for discharging heat generated from the IC 7. Then, the component parts of a stator core 1, a winding 3, the printed board 4, and the like are integrally modding-solidified by thermosetting resin having electrical insulating property, to compose a stator. One end of the cooling fin 8 is abutted on the motor driving IC 7, and the other end is exposed from the end surface of a resin housing 12 formed by a resin mold, and when a bracket 13 on the counter load side is fitted on the resin housing 12, then the cooling fin 8 and the bracket 13 are composed so that they may be abutted to each other.
