Abstract: A drive apparatus includes a motor unit and an electronic control unit. The motor unit includes a first end frame, a second end frame, a stator, a rotor and a shaft. The control unit controls driving of the shaft. An outer wall surface of the stator is exposed between the first end frame and the second end frame. The stator is thus enabled to contact outside air directly so that heat radiation characteristic of the stator is improved.
