In an air conditioner in which an outdoor unit houses a compressor, an outdoor heat exchanger, and an outdoor blower, a rotation speed detector for detecting the fan rotation speed of the outdoor blower is provided in the outdoor unit. When the detected fan rotation speed drops to a predetermined value,
An air conditioner comprising: a fan motor drive controller that increases a motor torque for driving a fan motor of the outdoor blower. 2. A utility model in which the fan motor of the outdoor blower is an AC induction motor, and the auxiliary winding of the fan motor is provided with a plurality of taps in a multistage structure, and each tap is switched and controlled in stages by a fan motor drive control circuit. An air conditioner according to claim 1. 3 The fan motor drive control circuit receives an output signal from a comparator that determines whether the detected fan rotation speed has decreased to a predetermined value and from the comparator that has determined that the fan rotation speed has decreased to a predetermined value. The air conditioner according to claim 2, which is a registered utility model, and further includes a tap switching driver for switching a fan motor drive tap in one step. 4. The air conditioner according to claim 1, wherein the rotation speed detector is an eddy current detector or an optical detector.
