Thanks all for the quick feedback.
re. the gearbox/servo setup I'm considering off ebay... the fellow said

"I don’t have the oz/in but there is a general conservative rule of thumb:
Oz/in = (Watts * 1351) / RPM. This gives us 88.3 oz/in. This is a very conservative equation. I think the torque is well over 100 oz/in, as I can’t stop the motors with my hand."

I'm still dithering as to whether this will be strong enough to move the X and Y axis. Can anyone confirm this rule of thumb eqn.
The motors are Super L - Sanyo Denki L720-039E84, 170W, 32V, 7.9A, 2600 RPM with 250 Pulse Encoders. I'm hoping they are stronger than 100 oz/in.... does anyone else know how to convert Watts to oz/in? or know where I can dredge up a spec sheet for this motor? |
