This is on ebay with 7 days left I believe. current costs is approx $550 including shipping.
SPECIFICATION:
· 18 HP at 72 Volts DC ELECTRIC MOTOR
· 12 HP at 48V
· 9,000 RPM no load approximately
· 200 Amps full load approximately
· Ball bearing
· Rotation reversible
· Shaft 1” Diam. X 2 3/4" hallow splined shaft
· Size 7” X 17” including shafts approximately
· Shpg. 70 lb estimated
Only thing Im not sure about is the shaft that come out of the back of the motor? maybe can use that for a generator to power the lights and such? instead of using an accessory battery? or using it to help charge the accessory battery?
Can you find more information? Model number? Motor torque graphs?

Didn't see anything but this is the link I had in ebay for it. there is one bid on it for 399 I believe. Maybe the seller can get the info?
72V 18 HP DC ELECTRIC VEHICLE MOTOR
Nice motor but it may only be intermittent duty... Hydraulic motors are like that.
It says in the listing that it's 40 hp intermittent, and 18 hp continuous. Looks like a really nice motor. I'd still like to see some torque/speed data to know kind of what speed is best to run it at.
A no-load speed is not useful information for a series wound motor, because this is always very high. The way a series wound motor operates is the torque just slowly tapers off as the speed goes up, but doesn't drop fast like it does for a PM motor. This means its not smart to run them no-load, and they can actually explode if done so!

That looks a LOT like an Advanced DC motor...
Its got that weird face to it (bearings?)
Here's a pic of my motor..

notice the similarities... Ask what the model is, because ADC has torque curves for most of their stuff....

Yeah, I thought it might be an ADC too. However, then I thought - won't most series wound motors look similar (those that aren't pancake motors)?
Anyway - one thing to be wary of is look at the shaft - isn't that a curved spline that is permanently fixed? A slotted shaft is MUCH easier to work with...
EDIT: Oops just read the post - double shaft - however the other shaft is straight splines - easier than the curved spline but still not as easy as a slotted shaft...

The curved spline side will most likely be the side he would need to work with, because that's the face mount side.
