ABSTRACT:
A method of treating a core for a dynamoelectric machine with a hardenable liquid adhesive material. The core includes winding receiving slots, a plurality of layers of a dielectric material associated in overlaying relation in each slot, a plurality of apertures in each layer arranged in non-aligning relation, and a plurality of non-apertured sections in each layer disposed in overlaying relation with the apertures in adjacent layers. In this method, the liquid adhesive material is passed by capillary action through the aperture in one of the layers in the slots and channeled by capillary action past the non-apertured sections in the one layer and another layer interposed between the one layers and the slot. The liquid adhesive material is then flowed through the apertures in the another layers into communication with the slots.
A method of assembling a core, a core, a slot liner, and a method of assembling a slot liner are also disclosed.
