Claim 0:
1. A motor control device that controls a drive of a motor in a motor drive system including the motor, a rotation transmission system provided with a drive limiting portion configured to limit the drive while a rotation of the motor is transmitted and driven, the motor control device comprising:
an energization control unit configured to control an energization to the motor; and
an excessive return determination unit configured to determine whether or not there is a possibility of an excessive return exceeding an allowable return position, when a non-energization return control is performed to return the motor in a direction away from a movable limit position by an external force generated in the rotation transmission system by turning off the energization to the motor after driving the motor to the movable limit position where the drive is restricted by the drive limiting portion,
wherein
when it is determined that there is no possibility of the excessive return, the energization is continuously turned off, and
when it is determined that there is a possibility of the excessive return, a stop control configured to stop the motor by energizing is performed.
