[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The main motor rotor commutator is a vital component in the DC motor. Its main function is to achieve periodic switching of the current direction to maintain the continuous rotation of the electromagnetic field inside the motor, thereby driving the rotor to rotate continuously. During the operation of the motor, the main motor rotor commutator will inevitably produce carbon deposits. In the environment of coal enterprises, dust in the working environment will also indirectly aggravate the formation of carbon deposits. Therefore, it is particularly important to inspect and maintain the main motor rotor commutator.

[0004] During inspection and maintenance, operators usually use old-fashioned slotting knives (an old-fashioned knife-shaped handle tool) to remove carbon deposits from the main motor rotor commutator. The slotting knives have blunt blades, are heavy, and have low carbon removal efficiency. There is also a risk of cutting hands or squeezing palms when using the slotting knives.

[0005] The utility model patent with application number 201720092396.6 discloses a motor rotor commutator impurity cleaning device, which fixes a drive motor connected to a brush on a support frame, and then uses a conveying device to transport the motor rotor commutator to the bottom of the brush for impurity cleaning. However, since the position of the brush is fixed, the cleaning range is fixed during cleaning. On the one hand, the cleaning of the motor rotor commutator details may not be thorough, and on the other hand, it cannot be applied to motor rotor commutators of different models.
