if SBE, ex Motronics, doesn't find an old data sheet on it, post physical size and voltage/speed you got no load again in 1 single post. from that, various of us will be able to compare it to similar rated motors we design, build, sell, service, and be able to make close guess what its current, continuous torque, and max speed ratings are for you.

Hi mike_Kilroy,

Look at this pic, it's the motor on the right side of the pic:

It's a PMDC NEMA 34 size motor, voltage is 24 VDC but it has no current rating marked on it...its shaft is round & smooth with no key or flat surfaces, the end of the shaft is conical.

This motor seems to be quite powerful, I did try to stop it by holding the shaft with a thick piece of cloth it barely slowed down with little rise on the amp meter, I don't think it reached 3A, I couldn't stop it & the end of the shaft got hot from the friction with the cloth.

I couldn't measure the speed under load.

you'll find more pics in the first post.

Thanks !
