MOTOR SIZING

Torque

Torque = F * r

where,

F- Force acting on the body(in N)

r- radial distance(in m)

T- Torque(in Nm)

width-7cm,length-10cm,height-2.5cm

Volume=0.00175m^3

density=1.15g/cm^3

mass=density*volume

mass-2.0kg

g=9.81ms^-2

Force=m * g

Force=2.0*9.81

Force=19.62N

radial distance=0.03m

Factor of safety=1.5

Torque net=4.58*1.5

Torque net=12.492N-m

Motor Selected for DC motor = 10 RPM

ADAPTER SIZING

(2PIn*T)/60

= 779.2/60

= 12V

Adaper = 12V
