<p>A motor control device of an air-conditioner is provided to improve reaction speed to a big error in PI control. A motor control device of an air-conditioner comprises: a plurality of switching elements; and an inverter supplying commercial AC power to a three-phase electric motor by converting transformed DC power to commercial AC power. The output current detection unit detects the output current of the inverter. A current command generating part(410) comprises a PI controller(510) producing the current command value by performing PI control. The switching control signal is output to the switching element of the inverter based on the current command value.</p> |
