backlash specification

Postby greg77 » Fri Feb 15, 2013 7:36 pm

Hi Folks,
I have noticed the backlash specification for all the planetary DC gear motors seems to be missing. Does anyone have specifications for the backlash on the phidgets gear motors. I'm specifically intersted in the "3272E_0 - 24V/50.9Kg-cm/53RPM 47:1 DC Gear Motor w/Encoder" or similar.

Backlash is a rather critical specification for any robotic application. I'm guessing its of the order of a few degrees(aka not very good) and hence that's why its missing? I hope I'm wrong because otherwise the motor specifications look quiet good.

Cant really say for sure but I seem to recall the manufacturers putting the number in the ballpark of 3 degrees as the absolute worst-case scenario.
