An interlock circuit (4) of a conventional motor control circuit (13) has been complicated, large-scaled, heavy, and expensive. A motor control apparatus (10) according to the present disclosure includesa motor driving unit (3) that supplies a current to a motor (6) ,a motor control unit (15) that transmits a control signal to the motor driving unit, anda cutoff apparatus (7) that is disposed between the motor control unit (15) and the motor driving unit (3) and that cuts off the control signal transmitted from the motor control unit (15) to the motor driving unit (3), when the control signal deviates from a predetermined range. It is made possible to determine an abnormality from an output of the motor control unit (15) and to cut off the motor driving unit (3), when an abnormality is determined. As a result, it is made possible to obtain an apparatus having an effective cutoff circuit, while suppressing the motor control apparatus (10) from being upsized, increasing its weight, and increasing its cost.
