Why is the air conditioner not cooling

1.Check whether the compressor is working normally. If the compressor is broken, the air conditioner cannot start normally and there will be no cooling effect. 2. There is not enough refrigerant in the air conditioner. At this time, you need to add Freon, and the time for adding Freon can be very long. 3. The air conditioner itself has quality problems and the electrical components have failed. In this case, you need to find a master to repair it.

Basic principle and optimization algorithm of BLDC

Brushless direct current motor (BLDCM,) gets rid of the inherent shortcomings of the brushless DC motor, and replaces the mechanical motor rotor with the electronic motor rotor. Therefore, the brushless DC motor not only has the excellent speed characteristics of the DC motor, but also has the advantages of simple structure, no commutation flame, reliable operation and easy maintenance.
