its old! looks single phase to me is there a data plate at all
Dont get my greasy mits on it till next week. Just wanted to get the jump on it so I know where to start testing it.
As the seller dint have any info I am assuming not. I did assume that it was single phase due to the cable but it still could be 3 phase with just a single phase out in use. Age is not a big issue in fact being old will mean that its solidly built & built to be fixable.
I am going to want to sort out a speed sensor so that I can set the tractor PTO rpm to the correct speed for 50 htz output.

i say single as the breaker is 2 pole. they are easy to set to the right RPM if you can measure the frequency some multi meters allow that. It will need an earth spike and a RCD. what are you planing to run with it?
I'm pretty sure it's a Froment/magnate probably 20kva at a guess, defiantly single phase. Ours is very similar but 3 phase- the 2 pole breaker is the give away.
Regarding the running speed/htz job, the light packed up on ours and looked like a blag getting a replacement so I ran it up with our spark checking the htz. It turned out that 50htz was exactly 540 on the shaft so now i just set the revs on the tractor screen and not use the light.

It mainly for a back up for our main genny which keeps letting us down with silly little faults but we need power whilst we wait for parts. Plus if it is the one mentioned above (thanks) then it will get used for the welder. Whilst being used as a back up it will be feeding into a quality fitted type (not a loose in car type) pure sine inverter/charger with pass through to the house. The house has RCD's & has an earth rod that the main genny is wired up to as well. As this will be sited further away it will either have its own earth rod or use the earth & screen on the armoured cable to the house rod. Might also fit a CU at the tractor end as well just to be sure especially as I will be using it directly as well.
I could use the hertz display on the inverter to set the speed but it would be much easier to do it at the tractor with a meter or light. I doubt the speedo / tacho / pto indicator is that accurate on my old MF165 or even the slightly newer MF590 (if I can get the tacho working). Might be close enough though as long as its between 45-55 it would be ok.

could be wrong but the design looks very similar to a markon the colour is also very close

agree with that a Hz meter is not an expensive item
Thats what I thought too. Then when the load goes up it has a bit of room if the load pulls the engine speed down. However from what I have been told tractors should hold the rpm quite well when the load changes due to the way the speed governor works (not like cars ones).
Keep the suggestions coming. Dont know if any are right yet as I cant find any pics that are the same as mine. Wont be here till Monday any way so plenty of time.
Remember this thread?
Well I have just got round to testing the genny. I was waiting for a cheap PTO shaft to come my way but it was low priority so I dint want to lay out much (ok any) cash either. In the end I got a new one that came with my new PTO powered log saw. So with the borrowed shaft in hand it was time to check it out.
Took all the panels off & gave it a good clean out. It all looked in very good nick. Bearings felt smooth & sounded like a good bearing should. Brushes (all 4 as there are 2 on each slip ring) are all in good condition & nice & long. Slip rings could do with a polish up but as its not going to be used again for a while I decided not to. So time to spin her up. As soon as the pto speed picked up the indicator light for under speed came on followed by correct speed light at about 47htz which stays on till about 51htz when the over speed light comes on. Voltage was a nice steady 240v. Tested it with a 1000watt table saw. No change in htz or voltage so thats good too.
Just need to sort out a proper mounting for it now as its still bolted to the reinforced pallet it was delivered on

i would be reluctant to polish the slip rings as the plating is often not very thick. the brushers will give it all the polish it needs during use.
