x-team Brushless motor is the new star of the market in recent years, why the motor of the products in recent years are replaced by brushless motor? What exactly is a brushless motor, and what are the application scenarios of brushless motors? What are the advantages of brushless motors? Let’s take a look at the following.

Brushless motors are generally divided into.

1, brushless DC motor (BLDC).

2, permanent magnet synchronous motor (PMSM).

3, the reverse electric potential for the trapezoidal wave called brushless DC motor (BLDC).

4, for the sine wave called permanent magnet synchronous motor (PMSM).

Its control method is also divided into.

1. Square wave control.

2. Sine wave control.

Brushless motor application scenarios are also diverse, and our life is more similar to the blender, such as vacuum cleaners, scrubbers, portable car pump, etc.; children’s toys, electric scooters, electric booster, etc.; such as model airplane enthusiasts use models, drones, aerial photography tools, model boats, etc.; computer air-cooling system, shredders, electric bicycles, cameras, electric fans, refrigerators, air conditioners, electric car doors, all kinds of fans, pumps, etc..
Can be applied to so many products precisely because brushless motors have more advantages than traditional brushed motors

1、Thin, light weight, high power

The rotor of brushless motor uses permanent magnet steel, so it realizes thin, light weight and high power. It can meet the demand of miniaturization of the device.

2、More energy saving

The use of permanent magnets in the rotor of brushless motors reduces the secondary loss of the rotor and significantly reduces power consumption. This contributes to energy saving of the device.


Brushless DC motor consists of motor body and driver, which is a typical mechatronic product. Since the brushless DC motor operates in a self-controlled manner, it does not add another starting winding to the rotor like a synchronous motor that starts under heavy load under frequency regulation, nor does it produce oscillation and lost step when the load changes suddenly.

4、Service life

Brushless motor can work continuously for about 20,000 hours, with a conventional service life of 7-10 years. Carbon brush motor: It can work continuously for about 5000 hours, with a conventional service life of 2-3 years.

5、After-sales service

Carbon brush motor needs to replace the carbon brush, if the replacement is not timely will cause damage to the motor, and brushless motor, the service life is long, usually more than 10 times the brush motor, but the bad need to replace the motor, but the daily maintenance is basically not required.

6、Use effect

Brushless motor: usually digital frequency control, controllable, from a few revolutions per minute, to tens of thousands of revolutions per minute can be easily achieved.

Carbon brush motor: the old carbon brush motor generally starts after the working speed is constant, speed regulation is not very easy, series excitation motor can also reach 20000 rpm, but the service life will be relatively short.
Its brushless motor cost relative to the traditional brush motor cost will be relatively high, but because its work is more powerful, so now the application of brushless motor scenario is also more and more, if there is no no consideration of cost issues, brush motor is not comparable to brushless motor.
