Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/044299
Kind Code:
A1
Abstract:
Provided is a motor control device, which switches modulation modes to each other between asynchronous PWM control that controls a motor by fixing a PWM frequency and synchronous PWM control that controls the motor by making the PWM frequency proportional to a drive frequency of the motor, calculates a compensation value, on the basis of a state quantity immediately before switching that correlates with the components of the rotating coordinate system of the voltage to be applied to the motor, when switching the modulation mode, and compensates the voltage immediately after switching by the compensation value.
