Abstract:
1. A drive apparatus comprising: a motor including a cylindrical motor case that forms an outer periphery, a stator that is disposed on a radially inner side of the motor case and has windings wound about the stator to form a plurality of phases, a rotor disposed on a radially inner side of the stator, and a shaft that rotates together with the rotor; a heat sink extended in a same direction as a center line direction of the shaft from an end wall of the motor case; and an electronic control unit that is disposed on a heat sink side in the center line direction of the motor case, and performs control of drive of the motor, wherein the electronic control unit includes: wherein the semiconductor modules, the heat sink and the capacitors are arranged to overlap one another at least partly in the center line direction, and the semiconductor modules, the heat sink and the choke coil are arranged to overlap one another at least partly in the center line direction.
