1. Excessive wear of the bearing or poor assembly will cause the stator and rotor to rub together, damage the surface of the iron core, and cause a short circuit between the silicon steel sheets, increasing the iron loss of the motor, and increasing the temperature of the motor. At this time, use fine files and other tools to remove the burrs, eliminate the short circuit of the silicon steel sheet, clean it up, apply insulating paint, and heat and dry it.

2. Excessive force is used when removing the old winding, which makes the stolen slot skew and opens outwards. At this time, use needle-nose pliers, wooden hammers, and other tools to trim, reset the tooth slot, and add hard insulating materials such as green shell paper, bakelite board, etc. between the silicon steel sheets with gaps that are not easy to reset.

3. The surface of the iron core is corroded due to moisture and other reasons. At this time, it needs to be polished with sandpaper and then coated with insulating varnish after cleaning.
