Abstract: This disclosure discloses a motor control device including a main circuit, a voltage detector, and a controller. The controller includes a position controller and a speed controller, The position controller generates a speed command. The speed controller generates a torque command and controls a inverter based on the torque command. Further, the controller includes a torque limiter, and a speed matching instruction part. The torque limiter starts torque limiting by the torque command to a predetermined torque or less and cancels the torque limiting. The speed matching instruction part matches the speed command with a first position command speed after the cancellation of the torque limiting. The holding part calculates and holds an accumulated position deviation.

Abstract: This disclosure discloses a motor control apparatus including a controller. The controller includes a position controller and a speed controller. The controller is configured to control the inverter on the basis of the torque command. The controller includes a torque limiter configured to start first torque limitation which limits a commanded torque based on the torque command to a first torque or less in a case where the voltage detector detects that the DC voltage falls below a predetermined voltage, and to cancel the first torque limitation in a case where the voltage detector detects that the DC voltage exceeds the predetermined voltage. The controller includes a speed limiter configured to limit a commanded speed based on the speed command to a first speed or less in a case where the torque limiter cancels the first torque limitation.
