Motor sizing and battery sizing - S-Division-2022-2023-Odd/Repo-16 GitHub Wiki
For our course project DC geared motor is required.
T= μ x M x g x D/2 η Here,
μ= Coefficient of Friction
T= Load Torque in N-m (convert it into kg-cm)
D= Diameter of the pulley in m
g= acceleration due to gravity
-
η= Drive efficiency(assuming it as 0.9)
P= 2 x π x N x T/60 Here,
P= Power in watts/min
N= Revolutions per minute(speed)
T= Load Torque in kg-cm
| 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 the motor of 60RPM
| 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 | Dual-Channel Relay Module | 1 | 5V | 70mA | 70x1=70mA |
- We Will use the adapter of 12V
