- Known baked enamel wires have one with a electrical insulation from an insulating varnish electrical conductor on that with an additional Baking layer made from a solvent-based baking lacquer is provided. Glue with the help of this baking layer Windings made of baked enamel wires after a sufficient Heating by means of a surge, for example Fusion of the baking layers of the neighboring ones Wire turns to form a firm bond.
- the baking layer is made several times Apply and bake solvent-based Lacquer layers made.
- liquid, fusible baking varnishes used depending on the for the required viscosity of the coating process Paint contains about 65 to 90% solvent and accordingly a solids content of only 10 have up to 35%.
- Burning in the baking layer takes place in a separate oven, so that in addition to the Burn in the insulating varnish required oven additional oven for baking the baked enamel is necessary.
- the electrical conductor enclosing insulating lacquer film or the one above it applied baking lacquer film due to temperature hardened and the contained in the paints Solvent largely removed from the paint layers.
- the released solvent vapors are connected downstream Catalysts fed and burned.
- the solvents contained in the paints used are usually toxic, odor-intensive and caustic. This applies particularly to the baking lacquers with a Solvent content from 65 to 90%.
- a solvent Cresol As a solvent Cresol, Xylenol, Solvent, NMP, Butanol and others in Commitment. These form explosive mixtures when evaporating, through a correspondingly complex technology must be mastered.

- Application of the baking layer are also the Workplaces are not burdened as there are no solvent vapors to be released.
- the device according to the invention has lower energy consumption and one much simpler and cheaper construction than the devices of conventional design, since none second oven for baking the baking layer and Evaporation of solvent, not a downstream one Catalyst for burning the solvent vapors and none elaborate painting equipment for multi-layer Applying baking varnishes are required.
- One already existing device for the production of enamelled wires can therefore be easily Device for the production of Upgrade baked enamel wires.
- Also a conceivable one Production of the baking layer by extrusion of a suitable plastic is more complex.
- processing inventive or manufactured according to the invention Enameled wires for windings and when melting the Baking layers for gluing the neighboring ones Wire twists of the enameled wires to form a composite none Solvent released from the baking layers.
- the Windings can be used safely in devices, too which place the highest demands on safety Regulations have to be set, for example in devices for medical purposes as there are no solvent residues in the Enameled wires are present.
