Brushless DC motor is composed of a DC brushless motor body and a driver. DC brushless motor is a typical electromechanical integrated product. The stator windings of DC brushless motors are mostly made into three-phase symmetrical star connections, which are very similar to three-phase asynchronous DC brushless motors. 

Brushless motors can perform simple variable speed control. All important currents are determined by a separate external resistor. The setting of brushless motors is relatively simple. The motor can start and stop using the power supply of the circuit to complete the start timing sequence.

Brushless DC motors share the same working principle and application characteristics as general DC motors, but their composition is different. In addition to the motor itself, the former also has an additional commutation circuit, which is closely integrated with the motor itself.
