DougI have found that it is no big deal to increase the capacitance value on a running RV providing you have a fine graduation of you selection of caps in your tuning box.It is good to have a pile of 1Mf capacitors of 600 volts, oil filled types, and a long row of sturdy switches, looking like an audio mixing board as your tuning box.You go down the line progressively increasing the capacitance value gradually, and nothing bad happens. Most times, one capacitormakes no difference to the ammeter, because it is not such a big increment value to the 3 hp RV.So ok , same game, only go for power.Cheers Warren

Hi Warren
Not trying to confuse., just saying any sort of prime mover motor could be used IF your generators are no lenz.....
Rotovertor is stuck in its sinewave speed so would need a VFD to test the generators at specific rpms that will give the delayed Lenz effect.
Why this design loops and with power left over is the generators are turned by belts and pulleys that put them into that delayed Lenz effect rpm window.
To find that rpm window you need to run the generators through wide rpm range until you find through the testing where amps drop low while generator is under load noe.keep rpm steady there, and loop it...msybe rpms drops some when you try and loop it, so if so, go for higher rpm initially and let the rpms drop into the delayed Lenz effect window zone...this I believe why the flywheel. As Gary said original builder said he looped it without flywheel and flywheel only makes it easier to ":introduce" the load.
As for rotovertor shsft power, you must increase run cap uf to give the shaft some decent torque....the original lowest draw run cap value at idle with no load on shaft will stall the shaft very easy with just light load on shaft so you need to increase run cap uf when turning loads...i found about 30uf gave me good power not so much extra draw with 7.5hp baldor as example. Be careful introducing large caps while motor runs!!! You might/will need to shut down motor and restart with new larger uf run cap in place
already, so use start cap to get it going from stop, and pull off start cap leaving just the new larger size if run cap.....try putting a 30uf cap on your rv motor as it runs very very briefly you will see lots of magnetic braking manifest...
