How To Select Motor Type For Your Electric motorcycle
1. The service life is different. The brushless motor can work continuously for about 20000 hours, and the normal service life is 7-10 years. The brush motor can work continuously for about 5000 hours, and the normal service life is 2-3 years.
2. The speed is different. The brushless motor can run at high speed of 90-95m / s. The running speed of brush motor is much lower than that of brushless motor.
3. The power consumption is different. The power consumption of brushless motor is only 1 / 3 of that of brush motor.
4. Maintenance costs are different. Brush motor is easy to be damaged and the maintenance cost is much higher. Brushless motor is not easy to be damaged, low maintenance frequency and low cost.
Disadvantages of brush motor
(1) High friction and high loss. Many customers encounter this problem, that is, after using the motor for a period of time, they need to open the motor to clean the carbon brush of the motor, which is time-consuming and laborious, and the maintenance intensity is no less than a family cleaning.
(2) Due to the structure of the brush motor, the contact resistance between the brush and the commutator is large, which makes the overall resistance of the motor large and easy to heat up. The permanent magnet is a thermal sensitive element. If the temperature is too high, the magnetic steel will demagnetize, which will reduce the performance of the motor and affect the service life of the brush motor.
(3) Low efficiency, low output power, the above mentioned brush motor heating problem, to a large extent, because the current work on the internal resistance of the motor, so the electric energy has a large degree of conversion into heat, so the output power of the brush motor is not big, and the efficiency is not high.
Advantages of brushless motor
(1) Brush less, low-interference brushless motor eliminates the brush, the most direct change is that there is no electric spark generated by the operation of brush motor, which greatly reduces the interference of electric spark on remote control radio equipment.
(2) Low noise, smooth operation, no brush motor, friction greatly reduced, smooth operation, noise will be much lower, this advantage for the stability of model operation is a huge support.
(3) Long life, low maintenance cost, less brush, the wear of brushless motor is mainly on the bearing, from the mechanical point of view, brushless motor is almost a maintenance free motor, when necessary, just do some dust removal maintenance.
The next comparison shows where the advantages of brushless motor are compared with that of brush motor.
When you buy scooter, if economic conditions permit, please choose scooter with brushless motor
