Title:
CONTROL DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/276593
Kind Code:
A1
Abstract:
A control device (10) comprises a control unit (S5) that controls a three-phase brushless motor (M). The control unit (S5) performs drive control to rotate a rotor to a target stopping position (TP) which is a target for stopping the rotor of the motor (M), and then performs hold control. In the hold control, a current is not flowed to the motor (M) if the rotation position (CP) of the rotor has not deviated from the target stopping position (TP), but if the rotation position (CP) has deviated from the target stopping position (TP), a current corresponding to the size of the load caused by the deviation between the rotation position (CP) and the target stopping position (TP) is flowed to the motor (M), so as to hold the rotation position at the target stopping position (TP).
