Abstract
This disclosure discloses a motor control apparatus including a current conversion part, a voltage control part, a current detection part, and a phase compensation part. The current conversion part generates a voltage command on the basis of a current deviation between a current command and an estimated current. The voltage control part controls an output voltage to a motor. The current detection part detects a motor current. The phase compensation part inputs the detected motor current and the voltage command and outputs, as the estimated current, the motor current in which a delay in phase of the motor current relative to the current command has been compensated.
