Although brushless motor has a history of decades abroad, it really started in China around 2000. It has a history of more than ten years, but it has never been warm. Many large motor manufacturers used to make carbon brush motors. After starting with brushless motors, they also set up a special brushless motor department, but they did not focus on it. Many people predicted that brushless motor would eventually replace most of the carbon brush motors, but more than a decade later, the generation of domestic professional brushless motor is not optimistic, on the contrary, the scale of carbon brush motor is very large.

In theory, brushless motor has the advantages of low noise, low energy consumption, long service life and so on, which are comparable to brushless carbon motor. With the improvement of domestic water products and the requirements for energy consumption, people will need more brushless motors. So many people in the motor industry are very optimistic about this emerging motor industry. In fact, it's not as optimistic as you think!

Although brushless motor has many advantages, one disadvantage is the high cost! The high cost ultimately limits its scope of use. Take the micro motor used for electric barbers and electric toys for example. The motor using carbon brushes only costs 1-2 yuan, while the cost of using brushless motors is as high as 10 times! We have done several cases. After a month of development, the motor can finally meet the needs of customers, but finally the customer gave up. The main reason is that the cost is too high, because the terminal price of a barber is only dozens of yuan, and the production cost of the factory is increased by more than ten yuan, which is unimaginable. And for the barber, hundreds of hours of service life is enough, there is no need to use a brushless motor of tens of thousands of hours.

The application of outer rotor brushless motor is relatively mature at present. The main reason is that the cost of outer rotor brushless motor is low, which is a business that can afford at present. Inner rotor brushless motor www.51zh COM is mainly used for gear boxes, electric tools, machinery and other industries. However, compared with civilian products, the demand of these industries is limited. At the same time, the service life of the reducer also restricts the service life of the overall motor.

At present, the use of brushless motors in the electric self-contained industry and electric scooters is relatively mature. However, high-end brushless motors such as servo motors still cannot keep up with domestic technology.

Many people have been asking a few years ago, is the opportunity to brush the motor really coming? I don't think so!

There may be opportunities in the next 5-10 years. In this way, relying on the establishment of standardization in the whole industry, the cost can be really reduced only by establishing standardization. But the process is a little long. I think it took 20 years to establish the standardization of carbon brush motor.
