What are the causes of the vibration plate surface damage? How to handle Vibration plate surface damage causes and treatment methods are as follows:
1, due to the micro-gear motor, the air gap between the rotor is very small, so once the bearing serious wear and tear, heavy load or impact caused by a slight deformation or bending bearing, it will cause the rotor sweep chamber. Sweep the results of the chamber, ranging from the core surface abrasions, while the core wear and tear caused the winding shell burned. In the operation of the gear motor, even if the rotor only slightly sweeping sound, should immediately cut off the power, so that the motor to stop the work, and check. When checking, open the end cap of the gearmotor, remove the rotor, carefully identify the core scratches and scratches, and find out the cause of the scuff.
In general, the silicon steel sheet of the core scratches is annealed by friction and overheating, and as a result, the permeability of the silicon steel sheet is reduced. On the other hand, the end of the silicon steel sheet is often grinding burrs, and burrs to both sides of the fall, resulting in a short circuit between the silicon steel, so that the core of the eddy current increases, leaving hidden dangers. If not dealt with in time, with the aging of the core insulation, eddy current continues to increase, resulting in increased temperature rise of the motor, the result of motor cooling or even burned.
Once the silicon steel sheet is found on the surface of the burr, you can use a triangular scraper to scrap it, and coated with insulating paint on the surface of the core. If the teeth of the silicon steel sheet are loose, insert the mica sheet in the gap between the silicon steel sheets and apply the insulating paint. In this way, both can strengthen the insulation between the silicon steel sheet to prevent short circuit between the chip, but also can increase the strength of the core teeth.
2, winding insulation breakdown short circuit or winding to the ground short circuit and arc, so that the core surface burns, and vibration plate is often uneven. This is not only the normal operation of the vibration plate, but also lead to short-circuit between silicon steel, so that the core eddy current increases.
If the vibration plate stacks of deposits, can be used to scrape the scraper; if the vibration plate rugged, can be used to clean up the fine file. After the above treatment, in the core surface coated with insulating paint can be.
