Reasons that cause deformation of roller

The fix roller and movable roller are made of silicon steel plate which it is insulative in each other. It is a part of the motor's magnetic circuit.The reasons that causing the damage and deformation of the roller are as below:
①Bearing is excessive wearable and bad installation,causing the fix and movable roller rubbed each other,and the surface damaged. It cause a short circuit between the silicon,the iron loss is increase,and the motor's temperature rise too high. At this time,it should use the small file or other tools to remove the burr,and eliminate the short circuit between the silicon. After cleaning,smear with insulating paint,and then heating for drying.
②When tearing down the old winding,bcos of large force,it caused the slot slanting and opening outward.At this time,it should use the pointed pliers, wooden hammer or other tools for repair,and make the slot reset,add the green shell paper, plastic wood or other hard insulating materials into the gap between the silicons which parts' reset is difficult.
③For moisture or other reasons cause the core's surface rust.At this time,it should use the sand paper to clean polished,then smear with insulating paint.
④To produce high temperature that around grounding of the group burn the core's slot or the tooth.
At this time,can use the chisel,scraper or other tools to clean the deposition,then smear with insulating paint and dry.
⑤The link that the core combined with the frame is loose,can tighten the he original location loose screws.If the screws is unavailable,can drill holes and tap, tighten the screws.
