Abstract

A stator (1) for an electric machine (15), in particular a turbo-generator, has an insulating layer (13) made of a powder coating (5). Also disclosed is a process for impregnating and insulating the stator (1) of an electric machine (15) by totally impregnating the stator (1) with an impregnating resin (4), then coating it with a powder coating (5) at a temperature from 20 °C to 70 °C. The thus obtained insulating layer (13) achieves with a single coating application a resistance to heat and tracking currents higher than that achieved by wet coating. The powder coating (5) preferably contains an epoxy resin based on bisphenol-A. Since the powder coating (5) contains no solvents and is used up to 99 %, the insulating layer (13) is produced in a particularly environmentally friendly manner.
