Well if it's anything like my 9" GE it will be a kick ass motor if you advance the brushes and put 144 or 156 volts to the thing. Not sure you'd like to take it beyond like 4800 rpm but it will put out a s.it load of torque.

Looks like you get to be the first to use a 13 GE monster motor. Would love to hear how it performs. Putting it in a truck or something like that or a little old VW?

Well I hope to put it in a 1966 GT mustang !
My neighbor used one of those massive folklift motors like this one in his Buick Roadmaster. It works, but it's a pain in the butt to hook up because the shaft does not have a standard spline... it cost almost $1000 to make the shaft collar and then make the coupler. Plus he had to make custom mounts (they don't make 13-inch EV hoops... no one does
It was also wicked heavy........ he could have added four more batteries in the front if he has just gone with a lighter motor. You can get a nice 8-inch motor for 1/4th of the weight that will move most cars just fine.
Also, if you use that motor, you will have to put larger rear end gears in as well. Those motors don't like to turn over 2500 rpm, so without overdrive or tall gears, the car won't go very fast.... although they do have tons of torque. You could move an Escalade with that one!

OK bumblebee, you might be just the HERO for me. A couple of question my I ask.My neighbor used one of those massive folklift motors like this one in his Buick Roadmaster.

Whats the Pack voltage is he running at?
How well FAST does the car go?
What kind of controller is he using?
Since he has driven it has he notice anything with the brushes or Com
I have one of these motors in my garage as well! I have a GOOD shaft coupler for it!

Well we may not qualify since our 13 inch GE is in a pulling tractor, but we have a shorter version of that motor installed. We ran it last year one time at 72 volts and wayyyyyyy overgeared and it still drug a 8000 weight transfer sled 150 feet. Torque up the kazoo. We dont expect more then 3500 to 4000 rpm at the expected sagged voltage of 110 to 120 volts and have geared it for.
We are putting the finishing touches on a 170 volt 600 amp Headway battery for this year, will go to 800 amps next year.
We have a adjustible advance set up so we can find what is best (we can go up to 10 degrees).
That motor is half the price I paid for ours and is longer (ours has at least 4 inch less in the frame). It looks like this one might have an aluminium drive end bell, ours is cast iron and HEAVY. Our shorter motor weighs 305 pounds
If we didn't already have one I would be driving to Elgin IL right now to buy this one.
The 9 inch they have for $125.00 is pretty nice as well.
That thing would move an 8000 pound lift truck around at a good clip at 36/48 volts. Just think what it will do with a 3000 pound truck at 144 + volts.
That is a BIG motor, make sure you have the room and suspension to carry it.
I'm a little confused. Did you purchase the motor already or are you planning to? The ad you listed in the OP is for a current Ebay auction by MHWC, but you posted pics of a disassembled motor?! If you're planning to bid on it, MHWC's motors have been selling for a little over $200 recently. The bidders typically always wait until the last few days to post a bid, then have a little war in that last hour or so. I bid on a 13" Prestolite and was the winning bidder for a little while (in the last half-hour or so) then the war started in the last five minutes. I was just playing and gave up before getting in over my head. The winning bidder seemed to be serious and willing to go pretty far to get it, so go in armed and ready of you really want it.
As for the motor, big GE motors are typically beasts (in a good way). The motor that propelled Rocket to 7.60s is a Berube-built 13". The only caveat is it could be a SepEx motor. I bought my GE 11" from MHWC and thought I was purchasing a series wound motor, but it turned out to be SepEx. I was considering purchasing a 12" recently, and called to see how it was wound, but the guy didn't know (or seem to be too interested in finding out). Their customer service is really good, by the way, I just seemed to be asking for information that he wasn't accustomed to providing.

The motor in the picture is a Series motor hands down. You can tell by the field windings. Big fat flat wire. SepEx has thin round wire. It is series and a beast. Nice and clean too. I'd use it. Damn thing is long too. Makes for even better power. You will however need to add some cooling if you plan on racing this sucker. Wonder what that would do attached to the butt end of a VW Buggy and 220 volts of lithium at the track?
There aren't any pics like that in the ad, so I'm wondering if the internal pics are from the motor in the Ebay ad, or just provided as an example of a 13" motor. That's definitely series, but is that the Ebay motor? Is the Ebay motor the one Georgia wants, or was that just an example? MHWC doesn't typically provide diasassembled pics. It looks like they basically clean the motors up, spray some ugly flat paint on them, and sell them.
Nice wheelies!...Wonder what that would do attached to the butt end of a VW Buggy and 220 volts of lithium at the track?
I went back and read through again...
If so, the issue would be with the low bar count on the comm. Maybe it's not that big of a deal, but it would seem to be a limitation on how high you can go with the voltage. He would need someone like Major to give an idea of how far he can go with only 29 bars. I think the typical 11 & 13" motors used in performance/racing apps have like 47, 49, etc.
Maybe he does already have one. The Ebay auction link is confusing. Georgia?

Nope, he needs the Motor Guru Jim Husted to answer that question.
