A plurality of screw holes is formed in a heat sink thereby to fix the substrate. A resin member is provided between the heat sink and the substrate and has a plurality of motor terminals and a resin mold, which integrally fix the motor terminals by molding the motor terminals. The motor terminal has an embedded part, a L-shaped substrate-side exposed part and a motor-side exposed side including a curbed part. The resin member and the substrate are tightened together and fixed to the heat sink.

Abstract: In a motor drive apparatus for driving a three-phase AC motor, a first mounting part of a heat sink is formed along an end. A second mounting part is formed in a direction perpendicular to the first mounting part and includes a first column part and a second column part. Three motor relay FETs are mounted on the first mounting part. Six inverter FETs and two power relay FETs are mounted on the second mounting part. Leads of the FETs are electrically connected to an electric circuit substrate. Heat generated by the FETs is radiated to the heat sink through an insulating and heat radiating sheet. By thus arranging the FETs, the motor drive apparatus is reduced in size.
