Hi,
I recently disassembled an old Apollo printer I aquired. (Apollo's are rebranded HP's) It had 3 motors in it a tini stepper a medium size stepper and a plain dc motor.

The larger stepper is a PM55L-048 made by Minebea Co. They have good information about their motors on their site. The info can be found at:

http://www.nmb.com/english/product/rotary/pm_stepping_f.html

Now my question. They list the torque of their motors in N.m. I believe this stands for Newton meter's and if I'm reading the chart right, this motor would peak at about .2 Nm. What I want to know is how does this compare to OZ of torque?

Thanks

That should be 28.322 oz force/in. Hope that's the one you are looking for

1Nm=141.61 oz.in, so jgro has done the math ;)

Thanks that helps. Thinking about the gear ratio on the motor that sounds just about right.
Thanks

Hi everybody,

I just upload "Master Converter" in the Download section, it could help a lot of you with conversion.

I wish it could help.
