    Tips: Brushed DC motor with gearbox working principle

    DC power supply current flows along the positive to the left of the brush, the brush and commutator mutual friction. The current passes to the left of the commutator and flows into the coil, flowing from the right side of the coil, after the commutator segment on the right and the right of the brush flow back to the power of the cathode, formed a closed circuit.

    As in the main pole of coil magnetic field, the coil will be affected by the effect of electromagnetic force, due to the current in a different direction, the two coil side is the same size in the opposite direction of electromagnetic force, the two electromagnetic force is just formed the electromagnetic torque, under the drive of electromagnetic torque, The coil began to rotate. In a Brushed DC motor, coils are placed in slots in the rotor and it starts to turn.

    The left and right commutators rotate with the rotating shaft and the brush stationary, rotation after a circle, the right coil to the left and the left coil to the right. Because of the existence of the commutator segment, now the current directions of the left and right coil are the same as original, the electromagnetic force direction is invariable. From the perspective of space, the coil side in the same position by the direction of the electromagnetic force is always constant, which ensures the motor cycle rotation.

    However, for a coil, the magnetic field is different when the coil is rotated to different positions, resulting in the electromagnetic force received by the coil changing all the time. Therefore, several coils can be installed to ensure the uniform and stable force of them.
