There was an infamous test of Edison's generator in which 2 generators were in parallel, and they got into a feedback loop of some kind, and accelerated out of control until he disconnected them.
What actually happened? It implies perpetual motion.
Huh? How does oscillation imply perpetual motion? Likely each generator had a regulator on it and the two regulators interacted.

IIRC that was a problem with the speed control system, they had one speed the other up if it was too slow. Think finally both were coupled mechanically? to solve the problem. From a book I did read....
Yes. Martians stole it.

There is a thing called amature reaction. What happens is strong armature current overcomes the field flux. Usually it is seen in motors with field weakening for speed control, where the field regulation fails. This can cause the motor to accelerate violently, sometime spinning the armature off the shaft. I can imagine a pair of shunt generators where an oscillation between one being generator and one being motor could occur. This would have massive armature currents flipping back and forth between the two.

Ok, so if they accelerated alternately and not together that makes sense. Thanks.
Their are no Martians! It was bought up, like the 300 mile an hour carburetor, this time it was the power companies, they have it hidden away, never to be seen again. That is, unless someone posts it on Youtube.
