What are the solutions to the ring fire of the speed reducing motor?

The ring fire of the reduction motor not only seriously damages the commutator and brush device, but also causes different degrees of damage to other windings; what can be done to solve the problem of motor ring fire? The following is to introduce to you

1. When dealing with gear motor commutator, the commutator with blackened surface can be polished with sandpaper or commutator grinding stone; commutator with slight or shallow ablation points on the surface can also be polished with commutator magic stone; commutator with more serious ablation must be re-turned its outer circle; commutator with serious ablation must be re-made
2. Replace the damaged brush grips and brushes, make sure the brush grade of the gear motor is the same as the original one, and make sure the brush pressure is set evenly.

3. Weld and repair or replace damaged gear motor windings and other parts.
4. Treat the surface insulation layer of the windings and conductive parts of the gear motor, including scrubbing the particles of carbon and copper condensed on the surface of these parts with cotton yarn dipped in a little gasoline, alcohol, carbon tetrachloride and other solvents, and then measure the insulation resistance. When the surface insulation layer is scorched by the arc, the insulation resistance after treatment must be higher than the allowable limit, which requires the removal of the scorched insulation layer and re-insulation treatment.

5. reducer motor shaft tile processing, when the shaft tile appears low shaft current burn point, after scraping, the shaft tile can still be used. When the burn point is strong and deep, replace the spare shaft tile or recast the shaft tile. It is necessary to confirm whether the insulation layer of the bearing is normal when dealing with the shaft shim.
6. Tighten the loose screws fixed on the stator and bearing seat of the gear motor.

The above is the solution to the ring fire of the gear motor, I hope it will help you, for more information, please feel free to consult us!
