Abstract

The invention relates to fan motor control method of air conditioner, which is characterized by the following: when several hall sensors don't detect the fan motor rotary or rotary quantity over the normal error scope, the air conditioner will stop driving. Hence, the invention can detect the imperfect condition of fan motor driving and part of hall sensors, which guarantees the reliability of fan motor control.

Description

technical field [0001] The present invention relates to a fan motor of an air conditioner, in particular to a fan motor controlling method of air conditioner, so that it can detect the bad state of the drive of the fan motor, and at the same time detect the fan motor By detecting the defective state of the hall sensor of the motor rotation speed, the reliability of the above-mentioned fan motor control can be ensured. Background technique [0002] In general, an air conditioner is a device that processes inhaled indoor air and supplies it to a building or room to maintain a comfortable indoor environment. It includes: compressor, which converts the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure; , which expands into a low-temperature and low-pressure two-state refrigerant mixed in gaseous and liquid states; the evaporator absorbs the surrounding heat and evaporates the above-mentioned two-state refrigerant in a gas state; Side-...
