I want to know the answer to the following question:
What is the theoretical maximum of a brushless wound rotor?
All the background I'm provided with is that "If a precision means were available to instantaneously control torque angle and slip for synchronous operation during motoring or generating while simultaneously providing brushless power to the rotor winding set, the active current of the BWRSDF machine would be independent of the reactive impedance of the transformer circuit and bursts of torque significantly higher than the maximum operating torque and far beyond the practical capability of any other type of electric machine would be realizable.". Is that enough to answer the question?
Answer: no
