ABSTRACT:
In an air-gap dynamoelectric machine, relative movement between insulation on a winding conductor disposed in the air-gap and the adjacent surface of a channel in which a winding conductor is supported can give rise to shear stresses imposed on the insulation. The present invention provides an envelope between the insulation and the channel surface to reduce any shear stresses on the insulation. The envelope provides interior major, confronting surfaces, slidable with respect to each other, and which are not subject to contamination by thermosetting resin applied to parts of the dynamoelectric machine during manufacturing thereof.
