Abstract
An electrically conductive enclosure shield is disposed between a rotor enclosure and the rotor winding assemblies. The shield reduces transverse shear loads generated by non-uniform centrifugal radial forces in a generator rotor, while providing adequate electromagnetic shielding for the field winding. Ventilation holes in the shield enable ventilation gas discharge, and shallow ridges may be provided that serve as axial positioning guides for enclosure rings. Additionally, the enclosure shield advantageously adds axial stiffness to the rotor.
