6.5) Resource Specifications:

Torque = F * r

where,

F- Force acting on the body(in N)

r- radial distance(in m)

T- Torque(in Nm)

Diameter- 0.3 m , height-0.01 m .

mass-1.1 kg

g=9.81ms^-2

Force=m * g

Force = 10.9 N Radial distance = 0.03m Torque = 10.90.03 TOrque=0.32 Factor of safety = 1.5 Torque net = 1.50.32 Torque= 0.49N-m

Motor Selected : DC MOTOR

ADAPTER SIZING

Stepper motor load current = 100 mA

Total current = Load current * Safety factor

Total current = 1000 * 1.2 = 1200mA

Total current = 1200mA @ 12V

Adapter Selected = 1.5A @ 12V
