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.
