6.5 Motor Sizing

For DC Motor (conveyor belt)

  • Total Weight = 0.25 kg
  • Co-efficient of friction between Acrylic sheet and Foam board = 0.7
  • Total Frictional Force = 0.25 x 0.7 = 0.175 kg
  • Radius of action = 1 cm
  • Torque generated = 0.175 kg-cm
  • Torque after Factor of Safety = 0.175 x 1.5 = 0.2625 kg-cm

Therefore, selected motor for above calculated torque requirement is 60 rpm motor.

For Servo Motor (for seed and soil dispensing)

  • Total Weight = 0.1 kg
  • Total Force = 0.1 kg
  • Radius of action = 1 cm
  • Torque generated = 0.1 kg-cm
  • Torque after Factor of Safety = 0.1 x 1.5 = 0.15 kg-cm

Therefore, the selected motor for the above-calculated torque requirement is Tower SG90 motor.

6.7 Adapter Sizing

For DC Motor (conveyor belt)

  • Voltage required to run DC Motor = 12V
  • Current drawn by motor at full load = 300 mA
  • Number of DC Motors = 1
  • Total current required = 1 * 300 = 300 mA
  • Current required after factor of safety of 1.2 = 1.2 * 300 = 360 mA

Therefore Adapter required for DC Motor should be rated 12V, 1A.

For Servo Motor (for seed and soil dispensing)

  • Voltage required for servo motor = 5V
  • Stall current of Servo motor = 660 mA
  • Number of Servo motors = 4
  • Total current required = 4 * 660 = 2640 mA
  • Current required after factor of safety of 1.2 = 1.2 * 2640 = 3168 mA

Therefore Adapter required for Servo Motor should be rated 5V, 5A.
