@polarbreeze.   Quote:  ?hoptoad, could you please post your efficiency measurements??

I would but can?t. Polarbreeze, I recently moved interstate from a quiet little country town in South Australia called Marion Bay, to another bigger country town in Victoria called Torquay. Both towns are about 1000 km apart. All my equipment, models, notes, data etc, are safely tucked away in a locked cabinet in my shed back in Marion Bay. My wife and I only intended to be where we are currently living for a month?s holiday.

We?ve been here for 12 months now, and in the interim period, we have leased out our own property for holiday rentals. I have no idea if or when I might return home to South Australia.

I've looked at this from a theoretical viewpoint and I've come up with a hypothesis which maybe someone could test with a real motor/generator setup. I am assuming that the motor that's being used is a synchronous AC motor. The hypothesis is as follows:

A synchronous motor runs at a fixed rpm which depends on the frequency of the AC supply (and is more or less independent of load). If that frequency is changed, the motor speed will change accordingly to re-establish synchronism. Attaching the "generator" device to the shaft sets up an alternating magnetic field in the shaft of the motor, at a frequency which is a multiple of the speed of the motor (because there are multiple magnets/coils on the generator). This perturbs the alternating field in the motor, delivering an effect equivalent to using a higher frequency AC supply. In an attempt to re-establish synchronism, the motor speeds up.

There are several ways that immediately come to mind in which this hypothesis could be tested on the setups that are already in place. Comments?

Bravo, PB! 
Just the number of magnets/coils should alter the acceleration characteristics...

I'd also like to add a potential complexity... the magnetic (or whatever) "pulses" from the generator mixed with the 60Hz AC in the motor create a 'beat' frequency which the motor is attempting to synch with... and this beat freq'y will be changing as the generator speeds up.

But then again, aether22 and/or hoptoad feel that any feedback magnetic flux/field is way too small compared to the motor's msg-fld to really cause that much difference/effect??

More complexity... will the steady-state RPM be an integer multiple of the 60Hz?

Mark, it's great to hear some objective thinking on this, well done!

... feel that any feedback magnetic flux/field is way too small compared to the motor's msg-fld to really cause that much difference/effect...

In order to crack this, I think it's important to get away from "feeling" and get into "measuring". And also to figure out ways to determine objective measurements rather than terms like "way too small". It is actually quite straightforward to measure the field strength within the armature of the motor, by inserting sensors, and it would be very instructive to observe the waveform on an oscilloscope.

I've noticed that there's a tendency, among those who want to believe in a mysterious previously-unexplained external force, to keep everything vague because that's the way to keep the mystery alive. So IMHO it's important to keep everything very objective and measurable. The vagueness is an absolute killer to the credibility too, so it prevents people from taking it seriously.

With this and the fact that polar thought Thane really meant 'you have opened my eyes' I think we can all ignore polarbreeze and let him talk to himself.
I thought he was a skeptic and just wanting to argue but now I realize he really is that dumb.

Read him only if we need a laugh but hopefully not respond, he may then go away. (or not)

...I thought he was a skeptic and just wanting to argue but now I realize he really is that dumb.

So I take it that you disagree with that hypothesis. Can you offer an alternative hypothesis?
