6.6 MOTOR SIZING AND BATTERY SIZING
6.7 MOTOR SIZING
a) Factor of safety is considered as 1.2
Total mass(m)=2kg
Radius(r)=4cm
Force(F)=mg
=2*0.101
=0.202kg-cm OR 2020g-cm
b)Torque(T)=F *r
=0.202 *4
=0.808kg/cm OR 8080g/cm
c)Total torque(TT)=Torque *FOS
=0.808 *1.2
=0.969kg/cm OR 9690g/cm
d)Mass of electrnoic components=
430gm=0.4kg(approx)
| TOTAL MASS | RADIUS | TORQUE | TOTAL-TORQUE |
|---|---|---|---|
| 2 KG | 4 CM | 0.808kg/cm | 0.969kg/cm |
We will be using the DC motor of 30 rpm for our model.
6.8 POWER ADAPTATION CALCULATION
BATTERY SIZING
I= 300mA *Number of Motors *FOS
=300 *1 *1.2
=360mA
| Sl.No | NAME | SPECIFICATION | CURRENT SPECIFICATION |
|---|---|---|---|
| 01 | DC Motor | 60 RPM high torque side shaft DC motor | No load current=90mA and Load current=350mA |
| 02 | Arduino | Mega 2560 | 20mA |
