摘要： An electric power supply driver executes duty control of turning on and off of a selected switching element to supply electric power to a corresponding stator coil in a case where an actual rotational direction and a target rotational direction of a motor shaft coincide with each other. Furthermore, the driver sets an on-duty ratio of the selected switching element below a lower limit value, which is at least required to rotate the motor shaft through the power supply to each corresponding stator coil in a case where the actual rotational direction and the target rotational direction do not coincide with each other.
