(Summary description)The stator and rotor of the motor are the magnetic circuit part of the motor, which is made up of mutually insulated silicon steel sheets. The reasons for the failure of the stator and rotor cores of the motor are summarized mainly including the following points.
1. The iron core or the teeth are burnt due to the grounding of the winding. In view of this situation, a chisel or scraper can be used to remove the fused deposits, and then apply insulating paint to dry.
2. The fixation between the iron core and the base is loose. If this happens, you can fix it again. If the positioning screw is damaged, you should reposition it, and then replace and tighten the positioning screw.
3. When removing the old winding, the slot is slanted and opened due to excessive force. Faults caused by this reason should be trimmed with tools such as needle-nose pliers, wooden hammers, etc., to reset the alveolar, and hard insulating materials such as blue shell paper and bakelite are added between silicon steel sheets with gaps that are not easy to reset.
4. Bearings have been used for a long time. Excessive wear will cause the stator and rotor to rub together, which will damage the surface of the iron core, which will cause a short circuit between the silicon steel sheets, increase the iron loss of the motor, and increase the temperature of the motor. In this case, a fine file or other tools should be used to remove the burrs, eliminate the short circuit of the silicon steel sheet, and apply insulating paint after cleaning, and heat and dry it.
5. The surface of the iron core is corroded due to moisture and other reasons. Such failures need to be polished with sandpaper, and then coated with insulating varnish after cleaning.
