6.5 Motor And Battery Sizing Of The System

We will be using Three DC motor T = Fr= FD /2 where;

T= Torque

F=Force

D= Diameter

F = mg Mass of the kinematic animal=800gm=0.8kg

Diameter of the rotating gear = 0.06m

force = 0.8 × 9.8 =7.84 N

Torque= FD/2= 7.84 × 0.06 /2 =0.235 Nm

Safety factor= 1.5

Final Torque = 1.5 × 0.235 = 0.3525

as we know ; 1 Nm = 10.1971kg - cm

Therefore,

Torque in Kg-cm= 10.1971 x 0.3525 = 3.59 Kg-cm

we'll need a motor of 30Rpm.
