Abstract
A dynamoelectric machine that has at least one rotor component proximate a stator that is axially displaceable from the stator in response to pressure of lubrication oil delivered to its lubrication system has a system for changing axial displacement of each axially displaceable rotor component from the stator to cause a corresponding change in rotor-stator magnetic flux interaction, comprising: a hydraulic pump for generating a flow of lubrication oil; and means for regulating the flow of lubrication oil to the machine to develop a corresponding lubrication oil pressure that controls axial displacement of each axially displaceable rotor component.
