A study of transverse armature reaction in synchronous machines: By means of a second machine with an adjustable stator

It is well known that synchronous machines, when operated under certain conditions, do not behave as theory would lead us to believe. These differences from predicted results are not of serious consequences under normal operating conditions, but are widely in error when operation on charging a long unloaded transmission line, synchronizing power, and pull-out torque, are computed from the design constants. These things lead us to believe that certain changes in the theories of synchronous machines would be advantageous, and it is with this fact in mind that we make this study of transverse armature reaction.
