Abstract
A rotor is provided for use at high speed. The rotor comprises a stack of laminations held under compression between opposed flanges. The laminations have a plurality of teeth. Some of the laminations have lugs having passages formed therein through which the bolts that hold the stack in compression pass. The laminations serve to hold bolts against radial deformation at high speed.
