PTO generator help.

anyone know of a PTO generator for sale

Have just tried increasing rpm and now showing 50 hrz but now showing 280volts it is under very little load. Is this normal or is there a way I can adjust or stabilise this. Thanks for any help.

I would think that it's a good idea to put a 13 amp socket on it as well so that any thing can be plugged in.

Voltage reg is out of spec. Very important for motors they receive 50+hz, so fix the voltage issue.

The AVR needs adjusting. Can you see a small unit inside? Might look like this from a 3 phase unit. If you can see a potentiometer labelled volts like the small blue blocks bottom right of the unit, with white centres, try turning very very gently and see which way the volts change. If no change, reset to original position. Be extremely careful if doing it live.

Doubt it will be modern enough for an electronic avr - be capacitor based

Have attached some pictures of what I have have.

You are correct it's not modern enough have attached some pictured to the thread.

Have you tried putting a heavier load on the output as the voltage will normally read high when on low/no load, also are you using a decent meter to take the readings?

Yes is a good meter but have not tried a heavier load yet but will try it.

Has anyone ever upgraded by adding a avr? Thankyou everyone for inputs .

Yes, it gets done in rewind shops all the time. Its quite straightforward (I am a Winder though!) Choice of avr depends on resistance of exciter winding.
I suggest contacting George Roper of Roper electronics in Wolverhampton (I believe) He will advise and supply.

We have a ringrose 3phase generator we’ve had it from new and it used to power the parlour when we milked so worked last time we needed it. We’ve upgraded the whole shed now and have a bigger board further back in another shed. Is it possible to get these generators reconditioned and add safety etc and go straight into a modern 3 phase board to run the lights 13amp sockets etc as the only 3phase thing we still have is the compressor

Have a small diesel generator in a soundproof box 110/240v output last time I started it no volts although working perfectly last time I used it, what would be worth looking at first?

Difficult without seeing it but Worth having a check to see if any voltage of the windings
Maybe diode blown of fuse blown on the board
Make and model , pics might help
