6.5 MOTOR OF THE SYSTEM

A.MOTOR SIZING 1.Mass of the bot = 3kg

2.Radius = 13 cm mass =2kg Torque of bot = 4.76.

60 RPM Motor At 12V

B. Torque for the spinning blades.

*. Mass= 400grms = 0.4kg,Factor of safety=1.5

*. Radius = 5cm

*. F=M×R =0.4×5 =2.0

*. Torque=F×1.5 =2×1.5 =3.0

*. Torque of spinning blades = 3 kg/cm

200 RPM Motor At 12V
