1. Scope of application
Brushless motor: usually used in equipment with relatively high control requirements and high speed, such as aircraft models, precision instruments, etc., which have strict control of motor speed and high speed.
Carbon brush motor: usually power equipment uses brush motors, such as hair dryers, factory motors, household range hoods, etc. In addition, the speed of the series motor can reach very high, but due to the wear of the carbon brushes, use Life is not as good as brushless motors.
2. Service life
Brushless motor: Usually the service life is in the order of tens of thousands of hours, but the service life of brushless motors is also very different due to different bearings.
Carbon brush motor: Generally, the continuous working life of a brush motor is several hundred to more than 1,000 hours. The carbon brush needs to be replaced when it reaches the limit of use, otherwise it is easy to cause bearing wear.
3. Use effect
Brushless motor: usually digital frequency conversion control, strong controllability, 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 works at a constant speed after starting, and the speed adjustment is not easy. The series motor can also reach 20,000 rpm, but the service life will be relatively short.
4. Energy saving
Relatively speaking, the brushless motor controlled by inverter technology will save much energy than the series motor. The most typical ones are inverter air conditioners and refrigerators.
5. Future maintenance
The carbon brush motor needs to be replaced. If it is not replaced in time, the motor will be damaged. The brushless motor has a long service life, usually more than 10 times that of the brush motor. However, if it is broken, the motor needs to be replaced, but basic don't need daily maintenance .
