Conductor element with insulation and manufacturing process thereof

Abstract

The invention relates to an electric rotating machine, such as an electric traction motor and / or an electric industrial motor, with an improved insulation system for the conductor elements, and to a method for producing insulation for a conductor element. In particular, the invention relates to the insulation of slots in a laminated core of an electric rotating machine, as well as the insulation of all electrically conductive elements, sub-elements, and / or connecting pieces, including, for example, the end face of the laminated core. By producing insulation for electric rotating machines with a rated voltage greater than 700 V using a powder coating, either by a powder coating process or by fluidized bed sintering, as proposed here, the expensive winding tape impregnation process can be omitted.This makes it possible to do without mica tapes and, if necessary, to replace all, or at least some, parts of the insulation system with mica-free insulation, thereby also switching the application from manual to automated coating, which significantly increases productivity.
