Re: Denso Motor with CIMple Gearbox
Since I am learning to do some of these calculations this season as a mentor, let me take a shot at this. If anybody corrects my numbers, that's great since I want to know if I am doing it wrong.

Torque of the arm = 3.8 lb x 65 in = 247 in-lb = 3952 in-oz.
Torque at Denso motors after gear reduction = 3952 in-oz / 4.67 = 846 in-oz.
Torque per Denso motor = 846 in-oz / 4 = 211 in-oz (stall = 1500 oz-in)
Using the Denso motor curve, a denso can run at about 73 RPM at 211 in-oz of torque (while pulling about 4-5 amps).
CIMple boxes + arm move at (73 PM / 4.67) = 15.63 RPM = 0.26 rev/sec
0.26 rev / sec = about 90 degrees of motion per second.

Is this done correctly?
