THE DIFFERENCE BETWEEN BRUSHLESS MOTOR AND BRUSH MOTOR IN SINBAD
- Oct 11, 2018 -

Scope of application:

Brushless motor are usually used in equipment with higher control requirements than precision and high speed, such as aircraft models, precision instruments, etc. The cost of the motor and controller is very high, so it is applied to relatively high-tech equipment. 

Brushed motor are commonly used in power equipment, such as hair dryers, factory motors, household range hoods, etc. In addition, the speed of the brush motor can also be very high, but due to the wear of the carbon brush, the life is not as good as the brushless motor.

 

Service life:

Brushless motor typically have a service life of the order of tens of thousands of hours, but the life of brushless motor varies greatly depending on the bearings.

Brushed motor usually have a working life of only a few hundred to more than a thousand hours. When the limit is reached, the carbon brush needs to be replaced, otherwise the bearing wear is easily caused.

 

Effect of use

Brushless motors are usually digitally variable frequency control with high controllability, which can be easily achieved from a few revolutions per minute to tens of thousands of revolutions per minute.

Brushed motor generally starts to work at constant speed, and the speed adjustment is not very easy. It can also reach 20,000 rpm, but the service life will be shorter.

 

Energy saving and environmental protection:

Relatively speaking, the brushless motor is controlled by frequency conversion technology which is much more energy-efficient than the brush motor. The most typical examples are inverter air conditioners and refrigerators.

 

Future maintenance

Brushed motor needs to be replaced with a carbon brush. If the replacement is not timely, the motor will be damaged.

Brushless motor has a long service life and usually more than 10 times that of a brushed motor. However, if the motor is broken, the motor needs to be replaced, but daily maintenance is basically unnecessary.
