subject: Reasons That Cause Deformation Of Roller [print this page] Bearing 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.
When 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.
