Abstract
An inherent eccentricity between the rotor bearings and the stator shroud is reduced by intentionally fabricating into each of a pair of frame annuluses, outer and inner surfaces which are relatively eccentric, and then rotating the annuluses with respect to each other until the inherent eccentricity is substantially offset. A method is provided to determine the optimum relative rotational positions as a function of the measured inherent eccentricity, and restrictions in the number of possible rotational positions are considered.
