ABSTRACT:
A filler material for supporting the coil end portions at the diamond area of a dynamoelectric machine consists of a resin filler disposed in the vent areas between adjacent coil end portions and a plurality of spacer blocks disposed in the filler. The spacer blocks have a sufficient volume and coefficient of thermal expansion to prevent excessive build up of temperature during curing of the resin and to decrease the overall coefficient of thermal expansion of the filler material and adjust the thermal expansion characteristics of the filler material so that such characteristics more closely match the thermal expansion characteristics of the coils themselves. The resin filler comprises an epoxy resin and the blocks, which have a generally orthogonal shape, are constructed of a laminated fiber glass material. A bead of resinous material is provided at the edges of the planar surfaces of the orthogonally shaped blocks to prevent abrasive contact between the blocks and the adjacent coil end portions.
