Description

This is a 3 phase induction motor being used as a generator powered by a diesel engine burning WVO. Single or 3 phase power can be produced depending on setup.
The induction motor is rated to at 5.5 HP or 4kw and the little 165 China Diesel is rated at 2.2KW.

The motor is wired in the C2C configuration which means there is a capacitor across one leg ( 25 Uf in this case) and another capacitor twice that value ( 2xC) across another leg and no capacitor across the 3rd leg where the power output is taken from.

In this case I only had 50 UF capacitors so I put 2 in series which HALVES their value ( ie, 25uf from 50 Uf caps). If I had the right values I'd use 1x 25 uf and a 50uf OR, I could use 2x25 Uf capacitors in Parallel which ADDS their values.

As can be seen in this test the setup was producing over 2Kw which seems surprising given the rating of the little diesel. It was blowing a little smoke but not over loaded. I was running it on Straight Biodiesel so I may get a little more power out of the thing using regular diesel.

By using the C2C configuration you can get single phase power from a 3 phase motor in a total output. In other vids I wire the motor to have each phase separately which divides the output by ( 4Kw /3 = roughly 1.3 Kw each leg)

With the c2c method you could as shown run a 2kw+ load where as in using each phase separately you are limited to a 1300W max load on each leg.
Basically the capacitors work like electronic time delays to bring each phase into sync instead of them normally being 120o ( 360/3) apart. If you were to connect the legs together without the caps you would just create a dead short.

To get an induction motor to work like a generator you have to have capacitors to store some electrical energy to energise the windings and then over drive it 5-10% above it's normal motor speed.

I do not have plans or drawings. I do practical testing only.
There is much information on the net on this that people can get more detail from which is how I learned about this combined with hands on testing and experimentation.

And for the Fun spoilers that take the satisfaction out of sharing info on youtube:

This was a demonstration for the purposes of Videoing only.
Please don't bore me with safety sissy drivel and warnings. They will be deleted.

If you don't know what you are doing with this or are practically inept at hands on work, then don't do it.
I don't know you so really don't care if you electrocute yourself and if you want to sue me, go ahead because I have everything in my wifes name so you won't get a penny. :0)
