rotoverter loaded consuming 6,5 VA
« Reply #151 on: July 31, 2012, 07:51:19 AM »
Just to inform you that running rotoverter on even lower voltages, even if it is
 shaft coupled with another motor, can require very little power.

 Here, one of experiments I was doing yesterday:
http://www.youtube.com/watch?v=D7AJspQm1e8

 Industrial motor 5,5 kW (at 50 Hz) is powered from one phase, runs (1452 rpm)
 faster than standard rotation (1430 rpm) and consumes only 0,45 A at 14,5 V
 which is 6,5 VA (probably less than 6 W).
 The prime mover runs another motor of same type which is not loaded. The
 friction of both machines is the only load.

 It was running for half an hour and then stopped, probably the voltage went too
 low, maybe 14 V only, that was too low.
 Imagine how low power it would require if the bearings were ceramic.

Hi, i want somebody help me to replicate the portable rotoverter to use for 3 refrigerators 110 volts or make 3 portable rotoverter for each refrigeratos. I think the portable rotoverter is the best for me    being that i want to use something small, simple and powerfull and cheaper. and clean,the other samples of rotoverter are too much for me and for my needs. i have 3 phase with 9 amp each one. I am in Mexico so here is 60 hz.
I have 6 months translating and studing  documents and i am makin a  new resumen to find what is missing me to determine how to choose the motor, how to choose the rotoverter model to use appropriate for my needs.
I'v read the RE-OU v6-1, document in word how to convert electric motor in rv, The Energy saving aplications principles also the laymens_RV_STEP_BY_STEP3, I have saw the video ROTOVERTER koneheadx and also all the video from Prosperforall,  and many more and i cant determine how to replicate portable rotoverter to use for saving money in energy. I am determined to do that.
I am not an engineer why is a little dificult for me.
Thanks very much.
Help me any way.

  I found myself looking at the same topic this morning but was leaning towards capacitors instead for power factor correction. I have 5 soda coolers tons of flouo lights and with the way they go on off at different times and combinations Im guestimating about 60 % wasted energy. Soon as I can get my head wrapped around the cap thoery Im gonna try to transfer that to a Tesla pancake coil and hope that will do the power correction. Im not all that confident in caps. Im still trying to figure why charges would want to seperate in a cap.

Another scientific toy run as rotoverter, 99% power saving.

An example of big power saving when (idle) running three phase motor of nominal power 5.5 kW (7 hp). This motor needs only 4 W of active power and 5.2 VA of virtual power. It is run from one phase, at 18 V, 0.29 A, capacitor used 55 µF.
The same motor when connected to 400 V three phase grid consumes 400 W. Power saving is 99%.
The motor cannot be loaded more. Almost all the power is used for overcoming the friction.
Based on rotoverter published by Hector Torrez.

Rotoverter at first glance appears to be overunity but vars are not real power. voltage and amps must be in phase or they are not present at the same time. They need power factor correction added to all output measurements.  All that is left for this to work is convert imaginary power to real power lol. lots of voltage with no current one millisecond and lots of current with low no voltage the next millisecond is not real power it is an illusion of power. Efficient resonance idling with no extra power is useless. Except to avoid the inrush current of the next startup. If your idle time is short it may be worth implementing into a working motor but not overuntiny and most likely better to just shut the motor off during idle times. Run capacitors are implemented to keep motors efficiently running under load and have been for a long time.  Then motors can be shut off during idle no reason to leave a motor running rotoverter mode at idle if no work is being done just shut it off. Only a very small advantage to this  RV mode and cost of switching in and out the rotoverter mode for a short idle is foolishness with the quantity of motors that could be in a single plant.
