14 Claims

1. A method for producing a slot insulation system for an electrical rotating machine, the method comprising:

providing a formulation for a slot adhesive, the formulation including a resin, a catalyst, and a solvent;

mixing the formulation to form a wet lacquer;

applying the wet lacquer to an insulated coil and/or an insulated individual bar and/or one or more inner surfaces of a slot to form a solid film of slot adhesive;

inserting the insulated and coated coil and/or the insulated and coated individual bar into the slot;

connecting the electrical rotating machine;

heating the fully-assembled electrical rotating machine to cure the film, wherein the film is firstly melted and flows before curing and solidifying to form a thermoset material.
