PowerTech Generator Basler Voltage Regulator

No, because in my 120VAC in-phase case both generator stator windings are connected in parallel. Going back to my first drawing, T1 is connected to T3 (via the jumper) and T2 is connected to T4 at ground/neutral, so both windings see the same load at the T1/T3 node, both are connected to ground/neutral at T2/T4, so both supply current to the load equally and the torque applied to the rotor windings by the stators' magnetic fields is uniform throughout the full rotation. Here's the drawing:



In the 240V case, going back to the drawing (reproduced below), the loads are split at T1 and T4 and connected to ground/neutral at T2/T3, the stator windings are now in series. Now we can have a load on one stator winding independent of the other stator winding; hence, the unbalanced torque applied to the rotor windings, which causes the rotor speed to oscillate about an average velocity.

Both ends of each stator winding are brought outside the generator head for us to configure as we wish. The two ends of the exciter windings are also available to connect to the voltage regulator, F+ and F-.
