Re: Gecko and Servos Again !

Bill,

I wrote my previous reply before you posted the specs. Here's what
you have:

W = (2,600 RPM times 60 in-oz) / 1351 = 115 Watts

in-lbs/min = Watts times 531 = 61,065

This means the motor can push:

61,065 Lbs at 1 IPM, or
6,106 Lbs at 10 IPM or
611 Lbs at at 100 IPM and

So on. All depends on your gearing.

It would be equivalent to a 3-stack size 23 driven very hard or a 2-
stack size 34 driven comfortably.
