Abstract
A synchronous machine is operable in a starting mode of operation in which a magnitude of a parameter of power applied to a main generator portion armature winding of the synchronous machine is detected relative to a stationary frame of reference and is converted into field and torque producing components relative to a rotating frame of reference. A controllable power source coupled to the main generator portion armature winding is controlled during operation in the starting mode based upon the field and torque producing components.
