Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/090159
Kind Code:
A1
Abstract:
The present invention suppresses driving current phase fluctuation when seeking to switch between feedback control and open loop control. A motor control device (1) comprises: a current control unit (12) that controls a current by means of one among open loop control and closed loop control; and a rotational position correction unit (13) that, on the basis of a first phase difference, which is the difference between the rotational position of a rotor in a state in which the current control unit (12) is controlling the current via closed loop control, and a target rotational position for the rotor, and corrects a second phase difference, which is the difference between the rotational position in closed loop control and the rotational position in open loop control when the current control unit (12) switches from closed loop control to open loop control.
