When the motor is working, the coil and the commutator rotate, the magnet and the carbon brush do not rotate, and the alternation of the direction of the coil current is accomplished by the commutator and the carbon brush rotating along with the motor. A brush motor has a larger force than a brushless motor, with fewer wires and a positive and a negative wire. If the motor is reversed, it can be done by simply swapping the positions of the two wires. In the electric vehicle industry, brush motors are divided into high-speed brush motors and low-speed brush motors. There are many differences between brushed and brushless motors. The easiest way to distinguish between them is as follows: Brushed motors have carbon brushes, and brushless motors do not have carbon brushes. However, there are large brush motor noise, brush motors have been basically eliminated.
