Abstract: A method of positioning a shaft and an associated seal in turbomachinery utilizing electromagnetic bearings. The method comprises the steps of applying electrical power to the windings of the electromagnetic bearings in which the shaft center is in a first position and wherein the shaft is in contact with the associated seal. By adjusting the power to the electromagnetic bearings, the seal can be manipulated with the shaft by movement of the shaft in a series of moves of decreasing amplitude to a position in which the seal is out of contact with the shaft when the shaft is rotated at its centered position during normal operation of the turbomachinery. The shaft is in its centered position during normal operation when the shaft axis is substantially coaxial with an axis of the electromagnetic bearings. The series of movements of decreasing amplitude may include oscillations of decreasing amplitude about one or more axes, or may include rotation in a spiral with a radius of decreasing amplitude to move the center of the shaft from an initial position to a final position. Movement of the shaft is accomplished by adjusting the electrical power to the windings of the electromagnetic bearings.
