Abstract
A dynamoelectric device comprises a plurality of armatures arranged circumferentially about an axis, sets of electrically conductive winding members that extend axially through the stack of laminates and are positioned circumferentially between each adjacent pair of the armatures, and first and second layers of end-turn members. Each of the end-turn members of the first axial layer is connected to one of the winding members. Each of the end-turn members of the first axial layer extends clockwise circumferentially from its respective one of the winding members. Each of the end-turn members of the second axial layer is connected to one of the winding members and to each of the end-turn members of the first axial layer of end-turn members. Each of the end-turn members of the second axial layer extends counter-clockwise circumferentially from its respective one of the winding members. The winding members are each formed of Litz wire.
