# 6.5.1MOTOR SIZING AND BATTERY SIZING

## 6.5.1.2 MOTOR SIZING

For our course projec DC geared motor and 1 servo 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 Servo motor 1 4.8V 650mA 650x1=650mA
05 Dual-Channel Relay Module 1 5V 70mA 70x1=70mA
12V 5V
300mA = 0.3A 850mA = .85A

We know factor of safety = 1.2

12V 5V
0.3×1.2= 0.36A .85×1.2= 1.02A
