摘要:
There is provided a motor control device controlling an energizing state of a coil of each phase for driving a stepping motor having multiple phase coils. The motor control device includes a detecting unit configured to detect whether the stepping motor is out of step, and a reverse rotating unit configured, when the detecting unit detects that the stepping motor is out of step, to rotate the stepping motor in a second rotation direction reverse to a first rotation direction, which is a rotation direction of the stepping motor before detecting out-of-step, by a number of steps with which a stress received by the stepping motor is alleviated, before the stepping motor spontaneously rotates in the second direction.
