MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/080244
Kind Code:
A1
Abstract:
A motor control device (40) includes a drive circuit (41) and a control unit (50). The control unit (50) includes: a drive control unit (55) that controls driving of a motor (10) by feedback control based on the detected values from a rotational position sensor (13) that detects a rotation position of the motor (10); and an abnormality determination unit (52) that determines a disconnection failure. At the time of a one-phase disconnection, if an engaging member (26) is caused to move with, as a target valley portion, a valley portion (221, 224) adjacent to a wall portion (228, 229) in normal phase driving for driving the motor (10) using a normal phase, the drive control unit (55): performs feedback control such that the engaging member (26) is between the wall portion and mountain portions located on both sides of the target valley portion; and thereafter performs current limit switching control for applying a current limit to drive the motor (10) such that the engaging member (26) moves in the direction to the wall portion.
