摘要： 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 ΔI 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.
