RE: [CAD_CAM_EDM_DRO] Re:305oz Steppers! More torque, Scotty!!!! (Shes' breaking up, I cannah hold'er)

Hi Dan,

Just for fun, I looked up the steppers that I got from Sanyo-Denki

http://sanyo-denki-online.com/nema23.htm

232-180-DB 180 2 2.1 1.05 4.5 1.97 2.16 2.98
$102 $0.57

The rotor inertia is listed as 1.97 oz/in2 for this 180 oz-in stepper.

340 g-cm^2 = 1.86 oz-in^2 ??

That seems to be quite a bit different then the 0.00482 oz-in-sec2 for your
units. What am I missing?

P.S. Nice Steppers!
