For how much? I bet it is a good one, 50 years old at least.

Its amazing how those old motors just keep going and the new ones doent last a year.

$20. runs on 110 or 220 i have only run it on 110 though as the wiring info change plate is missing

I got the twin to that motor. I put it on a sander I made.

Motors and especially old ones are fascinating and there are many types. I use induction repulsion one on my lathe its brushes can be shifted to reverse rotation very torquey. I had an old 50 hp. single phase motor at one time until I looked at its amp draw at 220v, traded that off quick. Then theirs the infamous home made three phase rotary converters.  Motors like steam engines will handle short term overloads well, which makes them handy on sawmills. Frank C.

And the fact that the most torque a motor makes is just before stall speed which is different from anything else out there.  I think.... Where does steam have its most torque?

I collect old induction repulsion motors... They are the best.
Just think what a new one would cost today if they was still building them...

Ox, not sure where a steam engine has max torque pretty much through its whole speed range. Unlike most engines they will really lug at low speed, look at the mountain coal haulers you can hear each stroke. Their overload capacity comes from the boilers they act like a huge battery and can supply 200 to 300% of their rated power for a short time. Frank C.
