Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/075365
Kind Code:
A1
Abstract:
A motor control device (40) is provided with: an energization control device (52): and an excessive return determination unit (55). The energization control device (52) controls energization of a motor (10). The excessive return determination unit (55) determines the possibility of an excessive return exceeding a return permission position under non-energization return control, when the non-energization return control is carried out for returning the motor (10) from a movable limit position in a separating direction by means of an external force generated in a rotation transmission system (20), by turning off the energization of the motor (10) after the motor (10) has been driven to the movable limit position. The turning off of the energization is continued when it is determined that there is no possibility of an excessive return, and stop control is performed for stopping the motor (10) through energization when it is determined that there is a possibility of an excessive return.
