Hi,
So when you over-excite the rotor of a synchronous motor, or under-excite the rotor of a synchronous generator, how is the flux actually changing the power factor of the armature to leading? (something to do with the magnitude of the armature reaction flux vector?)
That is to ask: by what mechanism does this modify the relation of the current to the voltage waveforms?
Pictures welcome.
Cheers!
