We had a contract to build a military building and we need to demolish the old military building. When we demolished the old building we removed an ac power conditioner from the building. It was used to condition the power that goes to their electronics building to prevent power surges and shortages. It has a general electric 200 hp ac motor that runs a 125 kw generator. Does anybody know what this unit is called or have a clue what it is worth?

You might look at it closely and be sure the generator isn't a 400 cycle. We use to call them converters.

I don't know if the military still uses any 400 cycle stuff, but it was once pretty common.

I have removed two similar GE units. (both units were at the same gov't facility).

Ours were 480/3/60 in, 208/3/60 out, circa 1964. They were still humming along with 100,000 hours on their odometers. They were superceded by big UPSs.

A very large paperweight (MG's). I have seen many go to the scrap yard for minimum coffee money. Very limited market. Good luck.

It looks like a 400hz mg set. Yes, the military still uses them, on Navy ship because you a smoother DC for electronics and gyros. They are worth more than scrap, especially if it is Bogue MG set. Which from the has the same characteristics.

Like I said "Boat Anchor". This link is for a Government internet auction for about the same piece of equipment with a starting bid of $50.00 and no bids yet. :no:

Thanks for all the replies. The name motor generator set seems so obvious! I don't know how I couldn't find the name of it. It seems to me that it would be worth a lot more than scrap metal. It has 200 hp electric motor that is rated for 1780 rpm, 460 volts, 236 Amps, 60 h, and 3 phase. General Electric AC generator is rated for 156 KVA, 125 KW, 1800 RPM, 480 Volts, 3 Phase, 60 cy, and 188 amps.

These were utilize extensively for power quality, for SCIFs, and for frequency conversion. Many are still in use today, but with new more efficient electronic UPS they are not as prevalent, and with the demise of the 400 hz main frames they have become as mentioned boat anchors.

I hand a guy call me he bought 11 of them at a government auction, and wanted to know where to sell them I said the Navy for the aforementioned boat anchors, He asked if I was serious I said yes he hung up.

I do believe 415 and/or 400 HZ are used by airports for supplying power to planes.

Try breaking them down and just selling the motors, maybe you'll get lucky.

400 HZ, very popular in aroenautics and cryogenetic labs,something with the coolers.

Start ups may like/need them. But with a good VFD etc..
Maybe scrap, maybe mooring. Much too valuable (and heavy) for an anchor.

I was thinking a 200 hp electric motor would be perfect to run all the hydraulics on a decent size concrete plant. And the generator has to be worth something.

Sort of doesn't make any sense to have a big motor pushing a big generator producing practically the same power! Might have been a government contract, no?

It doesn't make much sense, is very ineffiencient, noisy, a big Kw and heat load, but they have been delivering good clean power at the desired frequency to commercial, industrial and government facilities for decades.

We've got new stuff now . . . hence all of those loose 'boat anchors'.

Yes, I bought similar boat anchors at a government auction in 1972. Thought I made a killing, and would soon retire from the profit. Had to rent an all terrain fork, and temporarily put 'em out in the 'south forty', just till the fortune came in. Havent seen 'em for years, think the weeds got 'em . . . I'm expecting an EPA visit shortly!

Wow, John.
90/ton (short ton) is about 22.222222222222222222222222222222 cents per pound. My scrappey only pays 5 cents/pound US. I told him they were loaded with copper and other good stuff. Still 5 cents! Think I'll load 'em up and bring 'em to your guy !
