DC Brushless Motor Pros And Cons Contrast

Jan 12, 2018

DC brushless motor pros and cons contrast


advantage:


a) DC brushless motor is to use electronic commutation instead of the traditional mechanical commutation, reliable performance, never wear, low failure rate,


      Life expectancy than the brush motor increased by 10-30 times.


b) DC brushless DC motor is a static motor with no-load current;


c) high output efficiency;


d) External drive brushless DC motor can be small size.

e) DC brushless motor with built-in driver, due to thermal issues, the motor is running for some time, there was a fever.


f) Brushless DC motors have essentially no radiation.


g) DC brushless motor can also be combined with reducer, assembled into a brushless DC motor, long life, torque, low noise


 


Disadvantages:


a) Holzer-less brushless DC motor with a slight jitter at start-up, no vibration after normal speed;

b) Hollow cup structure of the DC brushless motor price is high, the controller requires high;

c) DC brushless motor with external driver, inconvenient to use, need external controller, difficult to control in size and cost
