rotoverter for power generation

[oouthere]

Just a passing thought, but if they really have a running looped rotoverter then why don't they place it on ebay?  That thing would easily sell in the thousands if not 10's of thousands of dollars.  It does not take two days and $500 to build one of these systems so he'd be making probably over $1k per day...sounds like good enough pay to me.

How long do you think it would take before the "boys" came around and shut down his little operation on ebay?

BTW looping an RV is dead easy anyone can do it. Just needs a bit of tuning thats all.  OU has always been here but most are too lazy to look and try it.

There is a whole lot of circuit sims going on over at EVGRAY now showing a loop, we are testing them also.

You can call this „saving energy” when running a motor idle in rotoverter configuration.
A motor 5.5 kW at 50 Hz or 6.6 kW at 60 Hz (7.5 hp) runs on real power less than 4 W on one phase, so theoretically it can be run from a small battery.

To achieve such result the motor bearings have to be well cleaned and slightly lubricated, the fan and the gaskets have to be removed. This motor shaft stops turning ~ 2.5 minutes after the power is switched off.

This film shows the data: ~3 W on the watt meter (the active range is 100 W), 0,21A on the amp meter (left) and 20.14 V on the volt meter):

And here is the update, actually only the short film on youtube:
You may remember, this is an old experiment I did, trying to run 5.5 kW 3 phase, 400 V 1430 rpm motor on as little power as possible.
