For our course project 1 DC geared motor is required.
T= Fr Load Torque in N-m (convert it into kg-cm)
V=68.550x10^-6
m=mass(64.437 x 10^-3)**
g= acceleration due to gravity (9.8)
F=mg (0.6443)
T= Load Torque in kg-cm (1.9331 approximately 2)
Rated RPM at 12V | Rated Torque in Kg-cm at 12V |
---|---|
1000 | 0.12 |
500 | 0.25 |
300 | 0.35 |
200 | 0.5 |
150 | 0.8 |
100 | 1.2 |
60 | 2 |
30 | 4 |
15 | 8 |
10 | 12 |
3.5 | 30 |
We will use DC motor of 60 RPM
Sl.no | Components | Quantities | Operating voltage | Operating current of each component | Total current |
---|---|---|---|---|---|
01 | DC geared motors | 1 | 12V | 300mA | 300×1= 300mA |
02 | Arduino mega 2560 | 1 | 5V | 100mA | 100×1=100mA |
03 | LED lighting | 1 | 3.6V | 30mA | 30x1=30mA |
04 | IR sensor | 1 | 5V | 40mA | 40x1= 40mA |
12V | 5V |
---|---|
300mA = 0.3A | 170mA = 0.17A |
We know Factor of safety = 3
12V | 5V |
---|---|
0.3x3=0.9A | 0.17x3=0.51A |
THEREFORE, 5A ADAPTER CAN BE USED FOR 12V POWER SUPPLY AND 5A ADAPTER FOR 5V POWER SUPPLY
