The invention provides a motor control device comprising a movement amount detection part, which can be used to detect the movement amount of the motor according to signals output by an encoder of the motor; and a control part. After the power corresponding to a predetermined first electrical angle is provided for the motor, the power corresponding to a second electrical angle corresponding to the moved direction of the motor can be provided for the motor. When the power corresponding to the second electrical angle is provided for the motor, the movement amount of the motor is equal to the movement amount corresponding to the differential between the first electrical angle and the second electrical angle, the position of the magnetic pole of the motor is disposed on the second electrical angle. When the movement amount is not equal to the movement amount of the differential, the influence caused by the interference can be determined, and the power corresponding to a third electrical angle, which is different from the first electrical angle, can be provided for the motor, and the determination of the position of the magnetic pole can be carried out. |
