I also have a pma and it does not take lots of turns to get the correct voltage. just rewound the stator. But anyways this is not something I have seen but something I am using at present. the only master and slave thing I know about is my 3 hp 3phase motor I use as my slave to power my air conditioning. extra output from my third leg recharges battery pack. not claiming anything crazy from that one just made it more efficient. the lost I get from my inverter is a lot but I can still run my air for about 8 to 10 hrs before battery charge is to low to power the inverter. recharge batteries from the charger and im on again. have not hooked up my pma to the motor as of yet but that may put me over. double stator permanent magnet alternator kicks out around 38 amps per leg-that's six legs on mine. as for having to take more turns to correct voltage-don't know what your talking about-adjust with pulleys and there you go. if u have to -step it down gain amps. use and learn about current transformers-knowledge is power.

With motors coupled run low rpm as motor then use as generator- Want more power use 1 to 1 pulleys two on high rpm motor and one on each of the low rpm motors. 16 amps from 2 amps Inverter off the battery-2.5 to 1 ratio on rpm same on hp. More motor/generators more power-do not load-do the math-it works!
These are small motors-less than 1/5 hp. Cheap and efficient. Please do not spend money and time on expensive setup. Everything else I have tried does not work. Uses to much amps to produce the same or less-no overunity. Small ac motor also works- from inverter- to run dc motor/gen remember to run dc motor as motor before using as generator. 24 volt quick charge to small 12 volt motor- makes motors produce more-be careful not to burn them out. I am sharing this 4 the people who want something that works-not for money or profit-just for us!

I have built a system that works. 2 small 12volt motors one high rpm one low rpm. high rpm motor uses 4 amps at load but there is no load just spinning so 2 amps. low rpm motor kicks out the correct 12 + volts at 8 + amps depending on coupled or pulley setup. this worked properly to run an inverter on it..but load eats your excess...so don't load-run to battery. motors where like 8 bucks a piece-that is overunity-no lie-just truth-januarywheeler@yahoo.com-enough for some lights and a couple of fans-my batteries are still full-so I know it works-like I said overunity burn 2 getting 8-people that say it does not work have not learned anything- but what is told to them in school-quoting some old theory-2013 wake up! my fan is blowing/ comp charging /and tv is on/ volt meter reading good, and my battery charger is charging my truck battery.no fancy stuff-just easy......
