I aquired some free steppers, the info on the label is as follows:

Crouzet Servo
82.972.011 Resistance: 2.6 ohms Step: 1.8 degrees P: 14,5w

Can anyone give me any info on decoding this?

Thanks for the help.

Well, 1.8 degrees means that each step is 1.8 degrees. Putting it another way, there are 200 steps per revolution. A nice number...

From ohms law I get they are 6.13 volts, 2.36 amps. They would probably work good with a xylotex board running a 24 volt supply.

There is no way to infer torque ratings is there?

And yes I believe they are either nema23 or possibly nema17. I haven't measured to be sure. They are four wire motors as well

I hope their NEMA34 frame, that should put them in the 250 or more oz/in range. If their NEMA23, they're probably closer to the 125 oz/in range, but typically would be faster motors.

You snuck in while I was typing. ;)

Then their Bipolar. I'd go with Geckos and hit them with 10X (60V) or more If I wanted to use them. But if their NEMA23s they may not suit your needs. If their NEMA17's I wouldn't count on machineing aluminum with them.

NEMA23s are abt 2 1/4" round (square or octal)
NEMA17s are abt 1 5/8" square typically.

I'm almost positive they are nema23s. These will be for a different machine...not my aluminum mill. Just something smaller as a starter project. I'm still getting the 300 oz/in motors for the aluminum mill! :cool:

This machine will be mostly wood work and possibly some vinyl cutting if I can figure it out. I think that would be cool because my friend paints cars and some flame stencils would be awesome!

Kool, Power is our friend! :D

I have considered making a CNC Vinyl cutter, but I talked to a friend tonight and hes giving me a HP D size plotter to try and convert. :cool:
