Bldc motor is a typical mechatronics product, which is composed of motor body and driver.Brushless motor refers to the brushless and commutator (or collector ring) motor, also known as the commutator motor.As early as the 19th century, when the motor was born, the practical motor produced was the brushless form, namely the AC squirrel-cage asynchronous motor, which was widely used.However, asynchronous motor has many insurmountable defects, so that the development of motor technology is slow.The transistor was born in the middle of last century, so the brushless DC motor which uses the transistor commutator circuit to replace the brush and commutator came into being.This new brushless motor is called electronic commutator DC motor, which overcomes the defects of the first generation brushless motor.
Advantages: a) Electronic switching replaces traditional mechanical switching, with reliable performance, no wear and tear, low failure rate, and a life span about 6 times higher than that of brushless motor, which represents the development direction of the motor;B) Static motor with small no-load current;C) High efficiency;D) Small in size.
