Now most of the cooling fans are brushless DC motor, which is greatly simplified in structure. The mechanical reliability of motor operation is enhanced, the service life is increased, the efficiency is high, the noise is small and so on. It is preferred by major industries. Let's introduce the principle of brushless motor.

Because the brushless DC motor is the evolution product of the brush motor, its working principle is to replace the brush commutation of the brush motor with the electronic commutation, so there is no spark problem, and it can tell the motor to run without replacing the carbon brush regularly. The brushless motor is more suitable for a variety of environments, with more protection and reliability. The power density of the brushless motor is small, and the motor heat is low, Smaller volume can produce larger power, unit volume motor output is large, motor power density is large, because brushless motor has no brush, the friction is reduced, the operation is smooth, the noise is also reduced a lot.

The above is a brief introduction to the temperature resistance of DC axial flow fans. I hope it can help you. Shenzhen dongxingyue Technology Co., Ltd. specializes in producing DC fans, AC fans, blowers and centrifugal fans. There are a variety of standard models for you to choose from. We have been established for more than 10 years and have done a lot of industry cases to understand the demand of various industries for cooling fans.
