How Air Conditioners Work

Air conditioners use refrigeration to chill indoor air, taking advantage of a remarkable physical law: When a liquid converts to a gas (in a process called phase conversion), it absorbs heat. Air conditioners exploit this feature of phase conversion by fo器2䀀

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.
