Abstract

A fan motor stopping apparatus includes a conversion circuit that converts alternating-current voltage supplied from an alternating-current power supply into direct-current voltage, a smoothing capacitor that is connected to a fan motor included in an air conditioner and smooths the direct-current voltage from the conversion circuit, a voltage detection circuit that detects a voltage across the smoothing capacitor, and a fan motor shutdown circuit that suspends the fan motor in operation when the voltage detection circuit detects a voltage less than or equal to a threshold that is preset for suspending the operation of the fan motor.
