고속 송풍기용 브러시리스 모터와 브러시 모터의 차이점은 무엇인가요?

From the high-speed blowing tube structure, brushless motor and brush motor are relatively similar, both have rotor and stator, brush motor rotor is a coil winding, connected to the power output shaft, the stator is a permanent magnet; brushless motor rotor is connected to the housing and output shaft of permanent magnets, stator is a winding coil, without the brush motor alternating conversion electromagnetic field when the use of commutation brush, no spark generation, more safe and reliable. So what is the difference between a brushless motor and a brush motor for high-speed blowers?

1、Application range:

High-speed blowers brushless motor: usually used for higher control requirements, higher speed equipment (such as aviation models, instruments and other motor speed control strict, higher speed equipment).

Brush motor: Brush motor is generally used for electric equipment, such as blowers, factory motors, household inhalers, etc. In addition, the serial motor speed is also high, but due to carbon brush wear, service life is not as long as brushless motor.

2、Lifetime

High-speed hair dryer brushless motor: generally used for tens of thousands of hours, but the service life of brushless motors varies greatly depending on the bearings.

Brush motor: Generally speaking, the brush motor has a continuous working life of more than hundreds to 1000 hours. Therefore, if the use limit is reached, the carbon brushes need to be replaced. Otherwise, bearing wear can easily occur.

3、Use effect

High-speed blowers brushless motor: usually digital frequency control, a few revolutions per minute to tens of thousands of revolutions.

Brush motor: carbon brush motor generally starts after running at a constant speed, it is not easy to adjust the speed, serial motors can also reach 20,000 revolutions / min. But the life span will be relatively short.

4、Energy saving

Brushless motors use inverter technology, much higher than brushed motors, typically inverter air conditioners and refrigerators.

5、Maintenance

Brush motor needs to replace the carbon brush, if the replacement will lead to motor damage in time, brushless motor life is long, generally more than 10 times the brush motor, but if damaged, need to replace the motor, but rarely need routine maintenance.

6、Noise

Has nothing to do with whether the brush motor, mainly depends on the bearings and the internal parts of the motor fitting state.

7, in addition to brushless motor parameters indicators, shape (outside diameter, length, shaft diameter, etc.), weight, voltage range, no-load current, current and other parameters, there is an important indicator: KV value, the value is the brushless motor performance parameters, is to determine the brush.

What is the difference between brushless motors and brushed motors for high-speed blowers? The above has made a simple explanation, Vacuz hope that it is useful to you, can help you Oh!
