Patent ID: 8125115

Claim:
A dynamoelectric device comprising: a stator, the stator comprising a core, a plurality of wire coils, an end turn phase insulator, and at least one lead wire, the core having a plurality of slots that are circumferentially positioned about an axis, the axis defining radial and circumferential directions and opposite first and second axial ends of the stator, the wire coils being wound through the slots and forming end turns as the wire coils wind from one of the slots to another of the slots, the end turn phase insulator comprising an end turn insulating portion and a lead wire restraining tab, the end turn insulating portion being sandwiched radially between at least two of the end turns, the at least two end turns being adjacent the first axial end of the stator and comprising an inner end turn and an outer end turn, the inner end turn being radially between the outer end turn and the axis, the lead wire restraining tab extending from the end turn insulating portion and from between the inner end turn and the outer end turn and being partially wrapped over the outer end turn, the lead wire extending between the lead wire restraining tab and the outer end turn, wherein the end turn insulating portion extends circumferentially about the axis a first arc length and the lead wire restraining tab extends circumferentially about the axis a second arc length, the second arc length is less than the first arc length, and wherein the inner end turn is formed by a first one of the wire coils, the end turn phase insulator has opposite faces, and the lead wire extends from the first wire coil in generally a first circumferential direction along one of the opposite faces of the end turn phase insulator and turns about the lead wire restraining tab in a manner such that the lead wire further extends therefrom in generally an opposite second circumferential direction along the other of the opposite faces of the end turn phase insulator.
