Abstract: An electronic control unit, for example, a rotating machine controller, is capable of driving one three-phase motor including a first set of three-phase winding and a second set of three-phase winding and one to three direct current motors. The direct current motor is connected to a position between one phase of the first set of three-phase winding and one phase of the second set of three-phase winding without redundancy. Inverters convert a direct current electric power to a three-phase alternating current electric power by an operation of bridge-connected plural switching elements, and apply a voltage to each phase in two sets of three-phase winding. A control unit controls a supply of electric power to the three-phase motor and to the direct current motor by controlling an operation of the switching elements.
