Brushless dc motor is what? What is its structure?

brushless dc motor is a kind of permanent magnet synchronous motor, is composed of main body of the motor and drive, and is not really a dc motor. Difference in brushless dc motor, brushless dc motor without the use of mechanical brush device, using square wave self-control type permanent magnet synchronous motor, with hall sensor to replace carbon brush and commutator rotor in ndfeb permanent magnet materials, the performance has great advantages, compared with the general traditional dc motor speed regulating motor is the most ideal.

the essence of the brushless dc motor for the dc power input, and into a three-phase ac power inverter, with position feedback, permanent magnet synchronous motor.

refers to the brushless dc motor without brush and commutator of the motor, also called no motor commutator. Motor before the last century was born, the practical motor is a brushless forms, namely the ac squirrel-cage asynchronous motor, this motor has been widely used. But asynchronous motor has many not be able to overcome the defects, so that the slow development of motor technology. Later gave birth to the transistor, and the transistor commutation circuit instead of brush and commutator of the brushless dc motor was born. This new type of brushless motor is called electronic commutator dc motor, it overcomes the defect of the first generation of brushless motors.

HOPRIO group a professional manufacturer of controller and motors, was established in 2000. Group headquarters in Changzhou City, Jiangsu Province.
