    Abstract: By recording the earth fault judge process of Siemens 1FE1 built-in water-cooled machine, this paper introduced the structure and characteristics of this type of electric machine, analyzed the electric machine insulation characteristic and used the practical service experience to enumerate the causes triggering insulation breakdown. The precautionary measures were pertinently proposed, as well as the improved thoughts, so that the designer has the site gist to improve the motor performance and dielectric strength and the equipment maintenance personnel have the thoughts to carry out the analogous site faults analysis.
    Key words: numerical control plano-boring and milling machine; water-cooled machine; variable frequency motor; turn-to-turn insulation
