6.5 MOTOR AND BATTERY SIZING of THE SYSTEM
There are total of 2 motors.
The appropriate motor for our design is DC MOTOR.
We will be using formula for torque as:
T=MgD/2(where M-mass in kg, g=acceleration due to gravity, Diameter in cm)
Subsystem 2-Crushing Unit
DC Motor
mass in kg, g=acceleration due to gravity, Diameter in cm)
r1=4.6cm,h1=4cm,r2=5.5cm
v1=3.142 x 5 x5 x 4 x 2
v1=628.4cm^3
v2=3.142 x (5.5x5.5) x 4 x2
