Well, It's now wired 240v delta, and it works as a motor (connected 240v across 2 wires and gave it a spin to start).
I tried connecting 50uf and 100uf as per the C-2C technique and have tried spinning up (with just a voltmeter connected across the 50uf) using a hand drill - Success!
It starts generating (well below 1500rpm - probably 250 - 300rpm) and puts out ~60volts - unfortunately my hand drill doesn't have the oomph to get it over 100v (I was driving it direct 1:1).
So my next newbie (stupid) question(s):
I'm a bit hazy on how to control the voltage - there's the fixed load system - where you have a (largish?) fixed load permanently connected:-
Will it start up with a load connected? - I though you shouldn't start/stop with loads connected as it demagnetizes the rotor? if you start up without the load, doesn't the voltage go very high?
what proportion of the generator output does the fixed load have to be?
I'd like to use a controller, (when I can make / acquire one) but initially a fixed load system may be the way to go - unless I can get a IGC quickly (any links to readymade & cheap controllers or simple controller circuits greatly appreciated). I'm currently googling but only found general ideas rather than circuits so far...
Also, given that the drill couldn't get it up to speed, will the pelton runner have enough torque? or do you spin up without the caps connected?
As I don't have a means of test running other than the drill, I guess I need to start to set up with the pelton wheel (still haven't bought the penstock so it's all still to do).
incidentally, I did find that book online as a pdf Equilux:-
