<p>A motor control apparatus can protect circuit elements in an appropriate manner while preventing an incorrect abnormality determination when a motor is in regeneration operation, etc. The apparatus includes a target current calculation section ( 51 ), a drive control section ( 52 ) that generates a drive signal based on a current deviation DeltaI between a target current (IMT) and a detected current (IMS), an abnormality determination section ( 53 ) that generates an abnormality determination signal based on the target current (IMT) and the detected current (IMS), and a regeneration operation determination section ( 59 ) that determines whether the motor ( 4 ) is in a regeneration operation state. When it is determined that the motor ( 4 ) is in a regeneration operation, a determination threshold of the abnormality determination section ( 53 ) is set to a value larger than a determination threshold during power running operation.</p> |
