Abstract
Some examples of the teachings herein include enamel-insulated wires. An example system includes: a round electrical conductor; and a wire enamel surrounding the electrical conductor. A layer of thermally unstable material includes at least one of: a lubricity constituent as topmost layer and/or a thermally unstable layer as a penultimate layer of the wire enamel directly bordering the surface.
Claims15
An enamel-insulated wire comprising:
- a round electrical conductor;
- and
- wire enamel surrounding the electrical conductor;
- the wire enamel includes a layer of thermally unstable material including at least one of:
- a lubricity constituent as outermost layer and/or a thermally unstable layer as a penultimate layer of the wire enamel, directly bordering the surface.
A method for producing an enamel-insulated round wire, the method comprising:
- applying polymerizable enamel material in a first layer to a round conductor;
- curing and polymerizing the enamel material in the first layers to produce a thin polymerized enamel layer;
- repeating the application and curing of enamel material in layers to produce a round wire with a multilaminar wire enamel system;
- and
- applying a thermally unstable layer over the multilaminar wire enamel system.
The method as claimed in claim 15, wherein heating includes electrical energization.
A method for producing a winding, the method comprising:
- applying polymerizable enamel material in a first layer to a round conductor;
- curing and polymerizing the enamel material in the first laver to produce a thin polymerized enamel layer;
- repeating the application and curing of enamel material in lavers to produce a round wire with a multilaminar wire enamel system;
- applying a thermally unstable layer over the multilaminar wire enamel system;
- drawing the conductor into a slot;
- heating the slot to initiate decomposition of the thermally unstable layer;
- immersing the slot in a liquid impregnating resin;
- and
- curing the winding at temperature.
