Title:
モータ制御装置
Document Type and Number:
Japanese Patent JP5726012
Kind Code:
B2
Abstract:
A motor control device has a motor driving circuit for driving a motor, a current detection circuit for detecting a motor current flowing through the motor driving circuit, and a controller for calculating a detected value of the motor current based on an output of the current detection circuit, comparing the detected value with a target value of the motor current, and generating a command value for allowing a motor current of the target value to flow through the motor based on a deviation therebetween, to output the command value to a motor driving circuit. The current detection circuit is configured of a first current detection circuit having a positive first gain and a second current detection circuit having a negative second gain obtained by inverting the first gain.
