Hi Jdaq

re: Asynchronous motors into generators

The wiki page on this is very interesting, but I have some questions which may make it even more so.

I have a 3 phase asynch motor with two modes: a 'Y' for starting and 'Delta' for 'normal running'. (this is how it has been described to me). There is a lever which switches between the modes.

I know very little about electrics but, living in the wilds in Sweden I would like to build a substantial generator from a Peugeot Diesel engine I have, combined with my motor. I use biofuels to power my vehicles (waste vegetable (cooking) oils) and I would like to make a generator that uses the heavier oils (preheated to make them less viscose) which are less easy to use in vehicles.

My home has a 'normal' 16 Amp per phase 3 phase supply and I would like to leave the electrical grid and become independant and use my generator set for combined heat and power. So the question is how to wire it up.

On the Wikipedia page 'asynchronous motor as generator' there is nothing describing the differences between Y and D connection and I wonder whether one or the other has any particular benefit for my application. And either way, what is the difference in wiring each to make them work. Can one wire it reasonably easily so that both work/are usable?

What are the maths involved in both of the modes for calculating the capacitors needed?

Any help with this would be gratefully received, if you have time to help.

Yours sincerely, Jules (progenator1)
