-0- ROTOR CONSTRUCTION FOR DYNAMOELECTRIC MACHINES APPARATUS Abstract Of The Invention A Salient pole generator includes a laminated rotor having an integral amortisseur winding and end supports. The rotor laminations have amortisseur winding and clamping openings adjacent the shaft portion of the poles. The end supports are cast to the stack of lamination as an inverted U-shaped member aligned with each pole. Each member has an outer amortisseur winding base portion and a pair of inwardly projecting side arms. The outer base portion includes integral coil support and fan projections and an inner inclined interior wall. The coil is wound about the pole, and the support side arms, and defines a radial air slot between the end pole lamination and the interior of the coil. The air slot has the inlet opening at the shaft and an inclined discharge opening at the outer end of the winding. The fan projections promote the movement of air through the slot and thus, over the backside of the winding and the end faces of the poles.
