Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a motor controller which can reduce vibration occurring in a motor even when a plurality of motors are driven. SOLUTION: The controller of the motor controller corrects the displacement of rotation angle to 180 degree by controlling the drive current of at least one motor and regulating the rotational speed of the motor when the displacement of rotation angle of both motors is 0 degree and the number of revolutions is 50 rpm (YES at step SA4). When the displacement of rotation angle of both motors is 180 degree and the number of revolutions is 25 rpm (YES at step SA7), the controller corrects the displacement of rotation angle to 0 degree by controlling the drive current of at least one motor and regulating the rotational speed of the motor.
