Motor control device and driving method of a stepping motor

Disclosed is a motor control device that controls an excitation state of a phase winding of each phase for driving a stepper motor with multiple phase windings. The engine control device includes a discovery unit which is so configured that it detects whether occurs at step motor is a stepping error, and a restoring unit that is configured so that it upon detection of a stepping error of the stepping motor by the detection unit, the stepping motor in a second rotational direction can, opposite to a first direction of rotation to rotate, which was the direction of rotation of the stepping motor before the step error detection, and is indeed reduced by a number of steps by which a load applied to the stepping motor before the stepping motor rotates spontaneously in the second direction ,
