In recent years with the increase of more large capacity generators the important auxiliary motor capacity increases. Stator coil fault events of this auxiliary motor often occur. Especial y the occurrence of inter turn short circuit fault can severely damage the auxiliary motors. The repair time is so long that it brings tremendous economic losses to the production enterprises. Therefore, this paper wil elaborate the course,examination, treatment and the reason analysis of the inter turn short circuit fault in a 4B Induced draft fan motor in some power generation. We’l summarize the experience and lessons, put forward the, provide reference and suggestions for the col eagues who are engaged in power generation enterprises. And that wil enhance the safe and stable operation of the units and provide assurance to improve the economic efficiency of enterprises.
