How does electrical motor work?
When the electrical motor working, the coil and commutator rotating but magnet and brush does not turn, the turning changes of the coil current direction is completes by the motor commutator and brushes of motor rotation. There are the clarifications of sub-high-speed brush motor brush motor and low-speed brush motor in the electric vehicle industry, a lot of difference between Brush motors and brushless motors can be seen from the name, brushless motor brush without any carbon brushes.
The main components of Brush motor are stator and rotor, there are poles on the stator (windings or permanent magnet), and the rotor has windings, there will be a angle between the stator and rotor magnetic field (N pole and S pole between), under the mutual attraction of the stator and rotor magnetic field, which is the stator and rotor magnetic field. After changing the seat of the brush you can change the direation of the angle between the stator and rotor pole, so as change the direction of motor rotation.
