A motor control device includes a rectifier which converts AC power into DC power and outputs it to a DC link, an inverter which converts the DC power of the DC link into AC power for each motor and outputs it, an AC voltage detection unit which detects an AC voltage value on the AC input side of the rectifier, a state determination unit which determines that a voltage dropped state has been set when the AC voltage value is smaller than a certain specified voltage and that a normal state has been set when the AC voltage value is equal to or larger than the specified voltage, and an output control unit which controls each motor in accordance with the amount of voltage drop with respect to the specified voltage of the AC voltage value when the state determination unit determines that the voltage dropped state has been set.
