Product Introduction

Brushless dc motor is a typical electromechanical integration product, which is composed of motor body and driver.
Brushless motor refers to the motor without brush and commutator (or collector ring), also known as the motor without commutator.
As early as the 19th century when the motor was born, the practical motor is the brushless form, that is, ac squirrel cage asynchronous motor, this motor has been widely used.
However, asynchronous motor has many insurmountable defects, so that the motor technology development is slow.
The transistor was born in the middle of last century, so the brushless dc motor with brush and commutator replaced by transistor commutator came into being.
This new type of brushless motor is called electronic commutative dc motor, which overcomes the defects of the first generation of brushless motor.

Production Application

Continuous load application

 mainly refers to the field that requires a certain speed but does not require high speed accuracy, such as fan, pump, blower and other applications, such applications cost less and are mostly open loop control.

Variable load application

 Mainly is the speed needs to change in a certain range of applications, motor speed characteristics and dynamic response time characteristics have a higher demand. Such as household appliances, dryers and compressors are a good example, the automotive industry in the field of oil pump control , electrical controller, engine control, such applications of the system cost is relatively higher.
