    I don't have any intentions of plugging it in, even if it only puts out 110v. It's just way to rare to be foolishly blowing up. Could probably figure out if it's a working machine with a meter alone and a little input from the people on these forums anyway. If there were a lot of them kicking...

    That is a very good question. There is some information in the pdf that tech99 gave a link for about radio interference from the power supply but I just skimmed it briefly. Most of it is over my head. There are three variable resistors on it. One on the cord coming from 32v, and another dial...

    Hi digoff.. I was thinking that I would try to reunite it with the proper caps. Otherwise it appears to be in pretty good condition, bearings are snug and turn well. So far I think the only other thing that it's missing is one of the grease nipples.

    Excellent, thank you.. He mentions that it's post war 1946. But hasn't been able to find much information about the manual. I sent an email to Newton Derby this morning, hopefully they have some information available.

    I think I got the idea that they changed names in 35 from Grace's. Looks like Newton Derby is still operating today but they have a sister company called: Winder Power that's been in business for a long time. It has an variable resistor on board, I wonder if that was to fine tune the...

    Because the name of the company changed in 1935 according to their website. https://Newtonderby.co.uk/about/history

    Oh.. Thank you. So some aircraft must have had 12v. I picked it up with a pile of 32 volt motors that I have yet to catalog.

    Sorry, I'm not to sure what you mean by: What is written on the crown x+y ? I don't see any writing on the crown.

    Interesting.. would think it would be 32v in, in those days.

    12 volt DC in and 1200 volt AC out?

    Thought I'd share this interesting old relic as I am unable to find any information about "type 28" on the Internet.

    Required voltage for this large saw (German three phase schematic)

    Shorted out? So is that why the weg21 burned out? Should each side of a winding go to one side of a capacitor? I wasn't actually planning to try and boot the saw with the Delta motor. Been looking for an 8 to 10 hp motor to be powered by the 14 hp Kohler engine. Going to try running some...

    Required voltage for this large saw (German three phase schematic)

    Sorry old Jim.. T1, T2 & T3 from the motor each go to a Cap. The other black wires go to a clip for the +12vdc to excite the windings. Some people say you need it and some people don't say anything about it. Interesting how the Weg 21 was putting out 240 without it. Especially considering the...

    Required voltage for this large saw (German three phase schematic)

    What I meant is that they are both 3 phase. Keep in mind that this is an experimental and very temporary setup. I do have a piece of welding cable and a spike for ground but the ground here is frozen solid right now.
