Re: INTERESTING ROTOVERTOR CIRCUIT BY PHIL WOOD

Body

I don't think the circuit is correct . 









This is correct and simpler to tune  (start cap omitted )  cap value in farads equals loaded transformer in henrys 

capacitor circuit is  136VAC  

primary of transformer is 120VAC , secundary of transformer is 13.8 DCP after diode bridge ,,,


henry

farad 

https://en.wikipedia.org/wiki/Farad https://en.wikipedia.org/wiki/Farad


the notion is one farad equals  1 volt       1 ampere 1 second 

 and the Henry                        1 ampere 1 volt       1 second 

In RE  the capacitor is the VOLTAGE node  and the INDUCTOR is the ampere node .. (standing wave resonance dynamics) 

capacitance = impedance  but opposed ! 

if in RV you replace a capacitor with an impedance the motor will run in reverse ....

if you switch  from a capacitor to an impedance or impedance to capacitor wile running an RV motor you can create a hell of a NEUTRAL spike EMP 
and have the motor tear the working table off the floor and or walls .

so be careful  EXTREME danger ....  you can also bring down the utility power system and collapse it with the neutral spike .. or blow your neighborhood transformer and or sub station  fuses ...

 Hi all
 This is rotoverto motor circuit done by Phil Wood from Australia  a few years ago (maybe could also be a Transvertor 3ph transformer circuit too?)
 ...note he has a small cap across each phase wind, then pulls out power from the run cap phase (virtual phase) of the rotovertor motor by first going through a FWBR, and then this charges a battery (lead acid I am sure) then note he has power go in series through a DC load....apparently this could be used at start-up to get the motor going, instead of using a great big UF cap for the start cap so energy is not wasted upon start up is one of its uses....This sort of replaces the run cap capacitor with a DC load I think is overall idea (two DC loads actually)
 This circuit might be dangerous if you connect that switch while motor is running at sinewave speed, and the DC load resembles the load of a start cap - it would make huge magnetic braking to the motor rotor and slam it to stop very abrupt motor could fly off bench break a rib or two like what happened to Norm...
