Brush motor has two parts of the stator and the rotor, the stator has a magnetic pole (winding or permanent magnet), the rotor has a winding, after the power, the rotor also forms a magnetic field (magnetic pole), there is an Angle between the stator and the rotor magnetic pole, in the fixed rotor magnetic field (between the N pole and the S pole) under the mutual attraction, so that the motor rotates. By changing the position of the brush, you can change the direction of the rotor magnetic pole Angle (assuming that the stator magnetic pole is the starting Angle, the rotor magnetic pole is the other side, and the direction of the rotor magnetic pole to the stator magnetic pole is the rotation direction of the motor), thus changing the rotation direction of the motor.
