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.
A method of assembling a core for a dynamo-electric machine, the core including a pair of generally opposite end faces, a circumferential yoke section between the opposite end faces, at least a pair of adjacent teeth extending on preselected pitch axes from the yoke section and between the opposite end faces, respectively, with each adjacent tooth having a tip end, a pair of generally opposed sidewalls on the adjacent teeth, respectively, an end wall on the yoke section interposed between the opposed sidewalls, the end wall and opposed sidewalls defining a winding receiving slot in the core intersecting with the opposite end faces, an opening between the tip ends of the adjacent teeth and the opposite end faces communicating with the slot, first and second sheets of a generally thin dielectric material, a plurality of first and second apertures extending through the first and second sheets and arranged in preselected patterns, respectively, each of the first and second apertures having wall means for defining the configuration thereof, a plurality of first and second non-apertured sections in the first and second sheets and interconnected between the first and second apertures, and each of the first and second sheets having a pair of opposite surfaces interconnected by a pair of sets of generally opposite marginal edges with adjacent ones of the opposite marginal edges intersecting each other, the method comprising the steps of:
A method of assembling a core for a dynamo-electric machine, the core having a pair of generally opposite end faces with at least one winding receiving slot interposed between the opposite faces, a pair of sheets of generally thin dielectric material, a pair of sets of apertures arranged in preselected patterns in the sheets and extending therethrough, respectively, a pair of sets of non-apertured sections in the sheets and interconnecting between the apertures, respectively, and the at least one slot including a pair of generally opposed sidewalls on the core, and an end wall interposed between the opposed sidewalls, the method comprising the steps of:
A method of assembling a core for a dynamo-electric machine, the core including a pair of generally opposite end faces, wall means in the core for defining at least one winding receiving slot intersecting with the opposite end faces, and a plurality of layers of generally thin dielectric material with each layer having a plurality of apertures extending therethrough in a preselected pattern, the method comprising the steps of:
A method of assembling a slot liner for a dynamoelectric machine, the slot liner including a sheet of generally thin dielectric material having a plurality of apertures arranged in a preselected pattern and extending through the sheet and also having a plurality of non-apertured sections interconnecting the apertures, the method comprising the steps of:
A method of assembling a slot liner for a winding receiving slot in a core of a dynamoelectric machine, the slot liner including a pair of sheets of generally thin dielectric material each having a pair of opposite surfaces interconnected by a pair of sets of generally opposite marginal edges with adjacent ones of the opposite marginal edge sets intersecting with each other, a plurality of apertures predeterminately spaced apart in a preselected pattern in each sheet with each aperture having wall means for defining its configuration and intersecting with the opposite surfaces, respectively, a plurality of non-apertured sections connecting between the apertures in each sheet, and a pair of generally opposite imperforate parts on one of the sheets extending along one of its opposite marginal edge sets, respectively, the method comprising the steps of:
A method of assembling a slot liner for a winding receiving slot in a core for a dynamoelectric machine, the slot liner including a pair of sheets of generally thin dielectric material each having a pair of sets of generally opposite marginal edges with adjacent ones of the opposite marginal edge sets intersecting each other, a plurality of apertures arranged in a preselected pattern and extending through each sheet, and a plurality of non-apertured sections connecting between the apertures in each sheet, respectively, the method comprising the steps of:
A method of assembling a slot liner for a dynamoelectric machine, the slot liner including a plurality of sheets of generally thin dielectric material with each sheet having a plurality of apertures extending therethrough in a preselected pattern and also having a plurality of non-apertured sections between the apertures, respectively, the method comprising the steps of:
