The difference between brushless generators and brush generators

Performance comparison of brushless and brushless motors


1. High force of friction and waste


Some customers often encounter this problem when using a brush motor, that is, it is necessary to turn on the motor to clean the carbon brush when the motor is used for a period of time.


2. High heat, short life

Due to the structure of the brush motor, the contact resistance between the brush and the commutator is very large, which causes the overall resistance of the motor to be large and easy to generate heat. However, the permanent magnet is a thermal-sensitive element. If the temperature is too high, the magnetic steel will demagnetize the motor, which will reduce the performance of the motor and affect the service life of the brush motor.


3. Low efficiency and low output power


The heating problem of the brush motor mentioned above is largely due to the fact that the work done by the current is on the internal resistance of the motor, so the electrical energy is largely transformed into heat energy, so the output power of the brush motor is not large and the efficiency is not high.


Second, the advantages of brushless motor


1, Without brush, low interference


The brushless motor removes the brush, and the most direct change is that there is no electric spark generated by the operation of the brushless motor, which greatly reduces the interference of electric spark to remote radio equipment.


2. Low noise and smooth operation


Brushless motor without brush, running friction greatly reduced, running smoothly, noise will be much lower, and this advantage for the model running stability is a huge support.


3. Long service life and low maintenance cost


Less brush, brushless motor wear is mainly in the bearing, from a mechanical point of view, brushless motor is almost a maintenance-free motor, when necessary, just do some dust maintenance can be.
