Abstract:
A slot armor for insulating the slots in the rotor of a dynamoelectric machine from the windings contained in the slots includes a high-dielectric film on at least one surface thereof. A layer of a tough lubricating solid is coated on the exterior surface of the film. The lubricating solid prevents abrasion of the film by radial motion of the windings with respect to the slot armor or radial motion of the slot armor with respect to the slots. In the preferred embodiment of the invention, a substrate of glass fiber/epoxy composite has a polyimide polymer film bonded to the surface thereof. The lubricating solid coating on the external surface of the polyimide polymer film is an FEP fluorocarbon.
