6.5 Resource Specifications
DC motor selection
Total volume= 615.70 cm^3. Mass = Density x volume = 0.96 x 615.70 = 591 gm.
Force= mass*coefficient of friction = 591 x 0.4 = 236.4 N.
Torque= Force x r = 236.4 x 15 = 3.546 kg-cm. FOS=1.5
Total torque= 3.456 x 1.5 = 5.319 kg-cm
Therefore, 30 rpm DC motor is suitable.
12V, 2A adapter is suitable.
Servo motor selection
Total volume= 517.12 cm^3. Mass = Density x volume = 0.96 x 517.12 = 496.43 gm.
Force= mass*coefficient of friction = 496.43 x 0.4 = 198.57 N.
Torque= Force x r = 198.57 x 3 = 595.72 kg-cm.
FOS=1.5
Total torque= 595.72 x 1.5 = 0.893 kg-cm
