MOTOR SIZING AND ADAPTER SELECTION - C-Division-2022-2023-Odd/Repo-01 GitHub Wiki

MOTOR SIZING :

Mass of body to hold (m) = 0.39 Kg

Radius(r) = 0.125m

Acceleration due to gravity(g) = 9.8 m/s^2

F = m * g

F = 0.39 * 9.8

F = 3.82 N

Now Torque : T = f * (D/2)

T = 3.82 * (0.25/2)

T = 0.47 Nm T = 0.47* (100/9.8)

T = 4.79 Kg-cm

Considering Factor Of safety i.e. FOS = 1.5

Final Torque = T * FOS

Final Torque = 4.79 * 1.5

∴ Final Torque = 7.185 Kg-cm @ 12V

∴ By comparing with table of specification for 7.1Kg-cm Rated Torque , We need Stepper Motor.

BATTERY SIZING:

Sl.no.	Components	Quantity	Voltage required	Current drawn
1	Stepper motor	01	12v	1200 mA
2	Arduino Mega	01	5v	40 mA
