    摘要： A motor control apparatus for preventing overvoltages due to the induced voltage when a motor (3) is rotated by an external force under the condition where an inverter circuit (1) is inoperative. The motor control apparatus includes halt occasion speed control means (52) which can reduce the motor's rotational speed when a command for starting the inverter circuit (1) is a halt command and when the rotational speed of the motor (3) is in excess of a given value, as shown in FIG 1. Consequently, when the motor is rotated by an external force, overvoltage due to the induced voltage can be prevented by reducing the motor's speed even if the inverter circuit is not in operation.
