The mini brushless motor factory introduces the performance difference between brush and no brush.
1. The brush motor has simple structure, long development time and mature technology
As early as the 19th century when the motor was born, the practical motor is the brushless form, that is, the AC squirrel cage asynchronous motor, which has been widely used after the generation of AC. However, the asynchronous motor has many insurmountable defects, so that the development of motor technology is slow. In particular, the DC brushless motor has been unable to put into commercial operation, with the rapid development of electronic technology, until recent years, it was slowly put into commercial operation, in essence, it still belongs to the category of AC motor.
Soon after the birth of the brushless motor, people invented the DC brush motor. Because of its simple structure, easy production and processing, convenient maintenance and easy control, DC motor also has fast response, large starting torque, and the performance of providing rated torque from zero speed to rated speed, it has been widely used once it came out.
