Hi Dave and Ron
I'm OK got apartment with wife outside of Seattle now...she has green card too...we are 5 minutes from my old workshop and lab....have not had internet for awhile just got it going..
I will keep everyone posted on the Gary P duplication of Tim's looper which Tim sold to guy on yacht in S America....All I know is the looper was wash machine pancake motor of older type, that had only 18 coils.....I think any of these sorts of motors will work as prime mover.
Use hall effects to time it and build or buy some sort of variable speed controller.
Connect this to a flywheel, spin it fairly slow but step up rpms to the BLDC motors working as generators with automotive belts (not toothed timing belts but regular slotted flat belts like for waterpump and alternators)
Simply find that rpm window where these motors with rotating magnet rotors will speed up under loading and not brake from lenz law...it might be just 200rpm window such as not under 2000rpm but not under 2200rpm you need to test this and find it using speed controller on that prime mover....not such a big deal eh..Gary mentioned spilitting the 3ph fields of the BLDC motors into three separate fields I will guess this is for the pulsing and timing sequencing using hall effects to time but not sure maybe he was talking about the prime mover pancake washing machine motor having this done to it, not sure about all this but whole concept and working model seems very doable and the looper on yacht now seems 100% legitimate to me...
So the looper had two BLDC motors, I do not know their model numbers or brands....Gary just belted 4 motors to his flywheel spun by wash machine pancake motor (some Samsung model all I know now) I really don't think it matters if fisher and paykel or Samsung or LG or maytag or whatever....these are great off shelf motors with lots of torque for very little input...
Look oin youtube Don Smith #187 for Gary's duplication confusing video however he might have some newer ones.,...Tim the looper builder who sold it to yacht owner had some youtuve videos up but I cant access them maybe later I can...both these guys open source both not too paranoid too so its all good will keep posting don't worry
