MOTOR SIZING AND BATTERY SIZING

MOTOR SIZING:

torque of dc motor

F=Mg M=0.09kg, g=9.8m/s^2 F=0.099.8 F=0.882N T=FR T=0.8823.5 T=3.087N-CM

Torque of two dc geared motor is

T=6.174N-CM

torque of servo motor

F=Mg M=100gm g=9.8m/s^2 F=0.19.8 F=0.98N T=FR T=0.9815 T=14.7N-CM

Torque of servo motor is

T=0.147kg-cm.

Total torque =6.32N/CM We are using 2Dc motor with torque=3.16N/CM=4rpm

BATTERY SIZING:

sl.no	components	operating voltage	maximum current
01	2 dc motor	12v	1300 mA
02	Aurdino mega	12v	100mA
03	servo motor	6v	10A
04	relay	5v	160mA
