How to distinguish the electric motor is brushless motor or brush motor?
From the appearance of the car, there are 2 ways to determine whether your car is brush or brushless: first, if there is a brush motor, the rotation of the motor forward is very light, relatively heavy when you turn back, you can clearly feel the resistance
Is the reversal of the same light, no resistance, or when it is turning, light reversal is a little heavy, refer to the first article, you know exactly whether your car is brush or brushless motor.
Brushless motor is the same as before and after the light. Two, brush motor only two power lines, brushless motor has 3 thick power cord, there are 5 thin Hall of the ear line, a total of 8 lines. You can try to use your hand motor car (the car just after the wheels)
Brushless brush "basic concepts: widely used electric bicycle is a permanent magnet DC motor, DC permanent magnet motor according to whether use the brush can be divided into brushless motor and brushless motor two, brush motor is the mainstream product of DC motor, the vast majority of electric bicycle motor a brush motor. Brushless motor is a DC motor special, it uses a built-in sensor and method of electronic commutator for electronic commutation of brushless motor, the main purpose is to eliminate the brush wear, and the noise generated by the brush contact.
