When a failure of a feedback control operation of an electric motor is sensed, a control unit changes the feedback control operation to an open loop control operation. At the time of executing the open loop control operation, the control unit sequentially changes the exciting phase of the motor without executing feedback of information of the count value of the encoder counter and rotates a rotor of the motor until a count value of an exciting phase change counter reaches an open loop target count value, which corresponds to a target rotational position of the rotor. When the control unit changes the feedback control operation to the open loop control operation, the control unit sets the open loop target count value by correcting a feedback target count value based on an exciting phase deviation correction value for the count value of the encoder counter.
