motor and wheels combination
« on: November 05, 2007, 02:22:52 PM »
which is the best combination of a motor and the wheels?


120:1,
25 in*oz,   motor  (with  31.2mm (1.23in) diameter and 11.2mm wheels)
145 rpm,
5V, 88 mA

or

143:1,
43 in*oz,  motor (with  65mm (just under 2-5/8"), by 7.62mm wide(0.3")   wheels)
70 rpm,
5V, 57.6 mA

an explanation will be appreciated

They are pretty much the same thing. From both combinations you will get about the same torque and speed, but the first is the best.
