PROBLEM TO BE SOLVED: To provide a motor control device, capable of easily performing control to take measures against power failure at the blackout of an AC power supply when driving a motor.;SOLUTION: A power failure detector unit 11a of an AC-DC converter device 11 detects power failure of a three-phase AC power supply 1 when a motor 3 is driven, to generate a power failure detection signal according to power failure detection. A transmitter unit 11b of the AC-DC converter device 11 transmits the power failure detection signal by using an electric cable, radio or an optical fiber. A receiver unit 12a of a DC-AC converter device 12 receives the power failure detection signal transmitted from the transmitter unit 11b.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
