Abstract

A stator of a rotary electrical machine includes a laminated core having grooves, windings inserted into the grooves for forming a multi-phase winding system, and an insulating layer made of plastic and sprayed between partial winding overhangs of the windings of phases inserted immediately one after the other. The insulating layer is formed as a mesh-like structure having junctions and brace-like connections running between the junctions.
