Patent ID: 7342331

Claim:
A rotor system, comprising: a rotor core configured to rotate about an axis, the rotor core including an annular section, a first pole, and a second pole, the first and second poles each extending radially outwardly from the annular section and forming an interpole region therebetween; a support wedge disposed in the interpole region; and a multi-plane balancing system comprising: a plurality of core channels formed in the rotor core annular section at a first radial location relative to the axis and extending axially through the rotor core annular section; a wedge channel formed in the support wedge and extending therethrough, the wedge channel disposed at a second radial location that is different than the first radial location; and one or more balance masses selectively disposed in one or more of the core channels and the wedge channel at one of the first radial location or the second radial location, each balance mass disposed at a predetermined axial location to thereby correct rotor imbalance.
