Lamination Clamping Structure

摘要

A generator rotor system having various features is disclosed. The generator rotor system has at least one main generator rotor with winding-pole sets spaced annularly about the rotor. The tendency of the rotor laminations of the poles to distort and or displace under the centrifugal force of the spinning rotor is ameliorated by a lamination clamping structure disposed axially outboard of the winding-pole sets.

1. A main stage generator rotor comprising:
a first winding-pole set comprising a winding and a pole comprising rotor laminations; and a lamination clamping structure, wherein the main stage generator rotor has an axis of rotation; wherein the lamination clamping structure is disposed proximate to the pole of the first winding-pole set and exerts a compressive force on the rotor laminations along the axis of rotation.
