브러시리스 모터가 브러시 모터보다 더 널리 사용되는 이유는 무엇인가요?

What is a brushless motor? The short answer is that it is a new type of motor that does not require brushes and relies on a commutator to change the voltage. Brushless motors have many advantages and have begun to replace traditional brushed motors in many industries.

One of the outstanding advantages of brushless motors for users is their long service life and ease of maintenance. At the current state of the art, long life is possible for most components in a brushed motor. The only limitation is the brushes, also known as carbon brushes, which are prone to wear because they are made of graphite. This is a consumable item that requires the user to replace the motor’s carbon brushes frequently and can suddenly break down due to increased wear, which can interfere with normal production. Brushless motors just solve the wear problem, not only greatly extending the life of the motor, but also requiring little maintenance, making daily use and production more convenient.

In addition to the easy wear and tear of carbon brushes in brush motors, there is another disadvantage that electrical sparks will be generated during the working process, followed by strong electromagnetic interference, which will affect the operation of the instruments and may even cause damage if there are precision instruments around. Brushless motors do not generate electric sparks during operation, thus eliminating the problem of electromagnetic interference, which determines that they can be used safely in many high-end fields.

In addition, brushless motors are more convenient to control, especially the frequency can be adjusted at any time to achieve flexible stepless speed regulation. For example, the air conditioner refrigerator is commonly used in life. The speed and power of the motor can be adjusted according to the actual situation, which can save power and improve the comfort of use.

I believe that brushless motors will be more and more in the future, the application cost of various popular products will also be reduced, to a certain extent, can replace the brush motor, but brush motor also has some of its advantages, some industries are still more applicable, and the price is relatively cheap!
