How to avoid scratches on DC geared motors

　　How to prevent the DC geared motor from scratching?As the equipment is currently widely used, the surface is easily damaged in daily use.The iron core will have scratches, how to avoid this situation, let's understand together.

　　Due to frictional overheating, the silicon steel sheet at the scratches of the iron core is annealed, resulting in a decrease in the magnetic permeability of the silicon steel sheet.If it is not handled in time, it will age with the insulation of the iron core.As the eddy current increases, the temperature rise of the DC geared motor increases, causing the motor to overheat and even burn.Since the air gap between the stator and the rotor of a DC motor is very small, once the bearing is severely worn, overloaded or impacted, the bearing will be slightly deformed or bent, causing the rotor to sweep through the hole.Due to the sweeping, the surface of the iron core was slightly scratched, and the iron core was severely worn, causing the winding to burn.During the operation of the DC geared motor, even if the rotor only has a slight sweeping sound, what we need to do is to immediately cut off the power supply, stop the DC geared motor and check.During inspection, open the end cover of the DC geared motor, take out the rotor, carefully find out the location and extent of the iron core scratches, and find out the cause of the scratches.
　　Through the above brief introduction of the motor on how to avoid the iron core scratches, we have learned that when the equipment is scratched, it is necessary to find out the cause in time and carry out equipment maintenance, so as to extend the service life.Hope this answer is helpful to you.
