摘要：
A motor control device has a current value sampling unit configured to sample a current value of a motor, a PWM signal generation unit configured to generate a PWM signal to drive the motor, based on the sampled current value of the motor, and a power supply stop unit configured to stop supply of power from a control power supply to a peripheral depending on power stored in a DC link part and power to which the control power source can supply when an alternating-current power source fails.
