End turn and terminal support for a stator assembly

Claim 1

A dynamoelectric machine stator assembly comprising: a magnetic core having an outer periphery, a bore, and longitudinally extending slots that extend radially from the bore to closed ends proximate to the outer periphery of the core; at least one winding having side turn portions thereof disposed within the core slots and end turn portions thereof disposed about at least one core face; portions of some of said end turns being in a compressed and shaped condition so as to establish a flattened region defining a predetermined space unoccupied by said end turns; the at least one winding having at least two tap wires extending from the end turn portions to a common connecting region near said flattened region; at least two lead wires each connected to at least one respective tap wire thereby establishing respective connection points; a connection insulator formed from at least one piece of sheet material electrical insulating material and having a sheet material base portion deformed into conformity with the windings and having a plurality of holsters, said connection insulator being disposed in the predetermined space adjacent the outer periphery of the end turn portions at the common connecting region adjacent to said flattened region, with said sheet material base portion conformed in shape to the contour of the end turn portions; said connection points being disposed within respective holsters of the connection insulator; and said connection insulator being retained in position on the outer periphery of the end turn portions and located radially with respect to the core between the outer periphery of the core and the closed ends of the slots.
