摘要： 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.
