ABSTRACT:
A method of assembling a core for a dynamoelectric machine with the core including a pair of opposite end faces, a wall in the core defining a winding receiving slot intersecting the end faces, and a plurality of layers of a generally thin dielectric material with each layer having a plurality of apertures extending therethrough in a preselected pattern. The layers are associated in overlaying relation, and the apertures in the layers are arranged in non-aligning relation with the apertures in each layer communicating with a non-apertured section of an adjacent layer, respectively. The layers in their overlaying relation are positioned in the slot, and one of the layers is interposed between another of the layers and the wall of the slot.
A method of assembling a slot liner is also disclosed.
