MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD

A motor control device drives a motor provided as a drive source of an electric actuator by performing vector control using d-q rotational coordinates, and sets a d-axis current command value so as to weaken field flux of the motor when torque is applied to the motor from the exterior in a direction...

Beschreibung
Zusammenfassung:	A motor control device drives a motor provided as a drive source of an electric actuator by performing vector control using d-q rotational coordinates, and sets a d-axis current command value so as to weaken field flux of the motor when torque is applied to the motor from the exterior in a direction that is the same as a rotation direction of the motor. When the rotational speed of the motor exceeds the predetermined upper rotational speed limit, the motor control device calculates a correction amount of the d-axis current command value so as to make a rotational speed of the motor converge to a predetermined upper rotational speed limit, and corrects the d-axis current command value by this correction amount.
