Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2013/058090
Kind Code:
A1
Abstract:
This motor control device generates a voltage command value from a current command value and performs feedback control by means of a detected current flowing through a motor. The motor control device is provided with: a correction control unit that, when the motor is being rotated at a set speed, sets a d-axis current command value and a q-axis current command value to each be zero; a current control unit that generates the integrated value of the deviation between the current command value and the detected current; and an integrated value measurement unit that measures the generated integrated value. The correction control unit adjusts the correction value for the rotational position of the motor by adjusting in a manner so that the measured integrated value becomes a value within a pre-determined range.
