Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2013/058122
Kind Code:
A1
Abstract:
This motor control device generates a voltage command value from a current command value, performs feedback control by means of a detected current flowing through a motor, and is provided with: a speed control unit that performs speed control of the motor; a voltage measurement unit that measures a voltage command value that is on the basis of the output of the speed control unit when the motor is rotating at a set speed; and a correction value calculation unit that calculates a correction value for the rotational position of the motor on the basis of the measured voltage command value.
