The present invention provides a motor control apparatus which limits a torque command according to input current or power. The motor control apparatus includes, a converter (11) which converts input AC to DC for output, an inverter (12) which converts the DC output of the converter (11) to provide an AC output for driving a motor (2), and an inverter control part (14) for controlling the same, and a numerical control part (15) which outputs a motor operation command for commanding the operation of the motor (2), and wherein when AC current or power input to the converter (11) lies outside a predetermined range, the inverter control part (14) controls the AC output of the inverter (12) so that the motor (2) is operated in accordance with a limited torque command produced by limiting a torque command originally specified in the motor operation command.
