Abstract
A rotor balancing system is provided that includes a rotor core, a plurality of core channels, a support wedge, a wedge channel, and balance masses. The rotor core includes an annular section, a first pole, and a second pole. The first and second poles each extend radially outwardly from the annular section and form an interpole region therebetween. The plurality of core channels are formed in the rotor core annular section and extend axially through the rotor core annular section. The support wedge is disposed in the interpole region. The wedge channel is formed in the support wedge and extends therethrough. One or more balance masses are selectively disposed in one or more of the core channels and the wedge channel, and each balance mass is disposed at a predetermined axial location to thereby correct rotor imbalance.
