1. A main stage generator rotor comprising:
- a winding-pole set comprising a winding and a pole; and
a winding retention member;
wherein the main stage generator rotor has an axis of rotation,wherein the axis of rotation has a radius,wherein the winding retention member is disposed outboard of the winding-pole set along the axis of rotation,whereby the winding of the winding-pole set is axially confined between the winding retention member and the pole of the winding-pole set, andwhereby the winding of the winding-pole set is constrained by the winding retention member from radially translating.

Abstract
A generator rotor system having various features is disclosed. The generator rotor system has at least one main stage generator rotor with winding-pole sets spaced annularly about the rotor. The tendency of the windings to distort and or displace under the centrifugal force of the spinning rotor is ameliorated by a winding retention member disposed axially outboard of the winding-pole sets. The winding retention member may also have a one or more cooling oil routing hole to enhance the flow of cooling oil among the windings.

11. A generator rotor system comprising:
-
a first exciter rotor; a second exciter rotor; a permanent magnet rotor; a first main stage generator rotor; and a second main stage generator rotor, wherein each of the first main stage generator rotor and the second main stage generator rotor share an axis of rotation; wherein the first exciter rotor is disposed at an axial outboard end of the generator rotor system, wherein the permanent magnet rotor is disposed at a second axial outboard end of the generator rotor system, wherein the second exciter rotor is disposed adjacent to and axially inboard of the permanent magnet rotor, wherein the first main stage generator rotor and the second main stage generator rotor are both disposed axially inboard of the first exciter rotor and the second exciter rotor, and wherein each of the first main stage generator rotor and the second main stage generator rotor comprise; a winding-pole set comprising a winding and a pole; and a winding retention member; wherein the axis of rotation has a radius, wherein the winding retention member is disposed outboard of the winding-pole set along the axis of rotation, whereby the winding of the winding-pole set is axially confined between the winding retention member and the pole of the winding-pole set, and whereby the winding of the winding-pole set is constrained by the winding retention member from radially translating. - View Dependent Claims (12, 13, 14, 15)
