UNTIMATELY WE WON'T NEED A MOTOR AND ARE WORKING TO ELIMINATE IT ALL TOGETHER AND USE THE GENERATOR COILS AS THE "MOTOR" TO BRING THE SYSTEM UP TO SPEED AND THEN SWITCH OVER TO GENERATOR MODE AND THAT'S IT. 

AT THAT POINT OUR INPUT WILL BE ZERO!!!

Humm.. I seem to have said the same thing in my response message 4657 to Baroutologos.

So the bottom line is IF any of Perepiteia anthousiasts want to harvest any considerable and usefull effects you must replace the induction motor with a pulsed permanent magnet motor or still better for greater efficiency with a Adams motor or even better Bedini SG motor type. (this advice goes for the inventor also).

my response was..
Actually I believe there is no need to change out the motor or even have a motor. The rotor magnets with his current cores/coils combination should be usable to get the rotor spinning. All Thane would have to do is add some rotor position sensors then pulse all the HV coils externally at the proper time to get the rotor spinning. Once at the needed RPM just disengage 3/4 of the coils and use only one to keep the rotor spinning. The other cores/coils can harvest the power. Part of that power can feed the remaining coil that keeps the rotor spinning.

Thane, thanks for the rotor layout. I now have some prints I can build from.. Can I use Aluminum or does the rotor need to be Steel ?

thanks,,,

UNFORTUNATELY THIS STUFF TAKES MORE TIME THAN SPECULATION AND ARMCHAIR INVENTING...

Good morning.
As always you have your way of saying things right. But give us a break Mr Thane
Personally i luck much of your experience in electromechanic art (apart form resources) But i plan to follow.

Anyway consider me as a supporter of yours.

Regards,
Baroutologos

ps:keep the good work going.

EXACTLY WHAT IS GOING TO BE DONE (WELL ALMOST BUT WITH A TWIST) ... BUT AS I SAID SPECULATION OR IDEA MANIFESTATION IS MUCH FASTER THAN PHYSICAL MANIFESTATION - SINCE WE HAD TO GET THE COILS RIGHT AS THE FIRST STEP.

ALSO BUILDING A MOTOR IS NOT ON MY WISH LIST OF THINGS TO DO... BUT IT LOOKS LIKE IT MUST BE DONE NOW.

BTW - THAT IS A LAMINATED STATOR CORE w/ A TOROID AS THE BACKING PLATE AND EIGHT SOLENOID FINGERS.

P.S.
THE TWIST

WE WILL USE THE E OR TOROID DESIGN WHERE WE EMPLOY AN INNER AND AN OUTER HV COIL.

THE INNER COIL WILL BE THE MOTOR COIL (UP TO A POINT) AND A GNERATOR COIL LATER ON... HOWEVER IN BOTH CASES WE WILL BE COLLECTING THE INNER COILS' DISCHARGED MAGNETIC FIELD INTO THE OUTER CORE LEG AND USING THIS TO BOOST UP THE GENERATOR OUTPUT AT ALL TIMES.    FUN TIMES!

I completely understand. I applaud your effort and your research. Yes, I can dream up ideas faster than I can build them but I do build some. .. The last couple, Mike's PPM and the whipmag, ended up not being successful but that was not from lack of trying.

After I had posted I realized that your prints were not the rotor. Interesting symmetry of where you are placing your coils. I presume your rotor is going to be the same one you are using which has evenly spaced magnets so I am guessing you have an idea to try out concerning coil placement in regards to magnet spacing.

Thanks for being so upfront and informative with your research.

THE COIL/CORE PLACEMENT IS DESIGNED TO REDUCE COGGING TORQUE AS MUCH AS POSSIBLE.

THE ROTOR MAGNETS ARE SEPARATED BY 20 DEGREES AND THERE ARE 8 CORES SO EACH CORE IS SEPARATED BY 2.5 DEGREES ALL THE WAY AROUND THE STATOR.
