DC brushless motor and permanent magnet synchronous motor differences are as follows.

1. Concept difference

DC brushless motor refers to a system, accurately called DC brushless motor system, emphasizing the integrated design of the motor and controller, is a whole, interdependence is high, the motor and controller can not exist and work independently, assess its overall technical performance; AC permanent magnet synchronous motor refers to the motor, emphasizing the motor itself is an independent working device, can leave the controller or inverter.

2. Performance difference

From the design and performance point of view, DC brushless motor system mainly considers how to turn ordinary machinery to electronic, and keep the advantages of mechanical steering motor after turning, the evaluation also focuses on the DC motor characteristics of the system, such as speed regulation characteristics; AC permanent magnet synchronous motor mainly focuses on the performance of the motor itself, especially the performance of AC motor, such as the power factor, voltage waveform and efficiency angle characteristics of the motor.

3. Using the potential waveform difference

From the perspective of counter potential waveform, DC brushless motor is mostly square wave, while AC permanent magnet synchronous motor’s counter potential waveform is mostly sine wave. The waveform is different, so their functions will be different.

4. Control difference

From the point of view of control, good quality and low price DC brushless motor system basically does not need algorithm, only need to consider the winding current according to the rotor position, if AC permanent magnet synchronous motor needs variable frequency speed control, need certain algorithm, need to consider the power and power of armature current.

From the above 4 points can be seen, DC brushless motors and permanent magnet synchronous motors have obvious differences, but they are both high-performance motors, can be used in many industries, as long as you understand the differences and links between the two, in order to choose the right motor in different occasions, to bring convenience to production!
