The structure and principle of the brush of the electric push-shear motor are relatively simple, and the brush is relatively easy to buy. Therefore, if the brush of the electric push-shear motor is broken, it can be repaired. Just unscrew the screw and replace the brush.

The principle of electric push-shear is that the magnetic field lines generate electromagnetic attraction to the armature through the iron core and air gap, thus driving the electric push-shear motor to work normally.
