Anyone got any ideas on what the Oz/In rating would be on these stepper motors. I think they're size 23 (Unipolar). The diameter is 2.25", Length is 2".
Google's not throwing much up.
Someone else maybe got the same motors and know the torque rating?

Cheers.

Long time no see.

Hey Gerry. Indeed. I've not been here in years. I've got the bug to build another machine again. I was just looking back through some old threads. It's good to see you're still here

My google search came up with this document; http://www.electrocraft.com/files/ead_step.pdf
Look under LA23ECK-6, which looks close to your ZA23ECK-6P. It ("LA23") is a 72 oz-in holding torque and is a 6 wire, thus either UNIPOLAR or BIPOLAR, depending how you wire it.
Is your stepper a 6 wire unit?

I did not see your original, but it is very simple, apply 3.4vdc to the winding and measure the in-oz etc with a fish type spring scale using a known dia pulley with a cord around it to the scale. A very old method. .
