Good question, no need to apologize.
Let's say for instance, we are working with a non-looped setup. Then I will cover the concepts involved in looping... The generator, even with an
energized prime mover connected to it, will not produce any electricity, until it is loaded down. If the generator is loaded, then the resistance of
the load will determine current draw from the generator. The generator and the motor both having service factor ratings. These ratings indicate how
far out of specification you overdrive either before damage is likely to occur. A typical service factor rating is 1.25. If your generator is rated
for 1.5 horsepower, and your prime mover is rated for less, then you don't have to worry about overworking the generator. The horsepower and newton
meters of torque the generator are rated for are just indicators of what the generator can handle mechanically and electrically, before damage is
likely to occur. If your prime mover is only 1 horsepower, that is not a problem. It just means that's all the prime mover is rated to supply to
the generator before stalling or breaking. Now, I highly suggest hooking your prime moving up to a Variable Frequency Driver, for several reasons.
The large capacitors in the VFD improve efficiency of the motor by forming a tank circuit, and the intelligent circuitry inside of the VFD, also
improves efficiency of the motor, by intelligently managing the power going into motor, so current draw is less when the torque is not needed.
And to reaffirm, as long as the generator head your using is high efficiency (meaning built properly in so many words), and is a high pole count, of a
recommended 24 poles or more, and this is connected and geared to a prime mover that is say four poles and highly efficient, and the gearing is
correct you'll have overunity. Also, be sure to use a VFD on the prime mover, and here's another reason why... Even when not loaded, the prime
mover will draw a lot of current if it's an AC induction motor. Essentially you are producing torque that is not being used, so if you hook it up to
the generator head like this, then you won't get over-unity unless you put a large enough load on the generator head. If you straight up loop the
system, you don't have to worry about that scenario. How I typically do it, is I rectify the three phase power coming off of the generator head, and
output it directly into the DC bus of the VFD. And the VFD is also hooked up to the wall, or an inverter for starting. As soon as the system gets up
and running, I just disconnect the wall power power. Simple as that. And in case the voltage off of the generator is a bit higher than the VFD
likes, I use an off of the shelf voltage regulated to regulate the rectified 3 phase AC intelligently.

With an electrical engineering background, and bench experience, it's all easy to do. I may have to do some videos, with myself and one of my
engineers at the bench going over all these concepts.
Let me know if you have any more questions, I am willing to answer them and get deep into this.
