Abstract:
1. A motorized equipment comprising: a motor case; a stator fixed inside the motor case; a rotor provided to be rotatable relative to the stator; a shaft that is fixed to the rotor and that is rotatably supported by the motor case; a plurality of power transistors that are provided on one axial side of the shaft outside the motor case such that the power transistors are electrically connected with extraction lines extending from a coil wound around the stator or the rotor, the power transistors supplying a drive current to the coil; a control board that is provided on a rotor side of the power transistors outside the motor case for controlling switching of the power transistors; and a heat sink that is provided on the other side of the control board opposite to the rotor side outside the motor case for absorbing a heat generated by the power transistors.
