MotorLab sizing suite
Conveyor motor sizing
Use Simple mode for fast torque and speed estimates. Advanced mode adds belt mass, slope, external drag, and duty-cycle RMS torque.
Inputs
Radius of wheel
mm
Max linear speed
mm/s
Load mass on belt
kg
Time to reach speed
s
Direction
Horizontal (H)
Friction coefficient
Coefficient of friction for horizontal systems.
Bearing drag torque per bearing
Nm
Number of bearings
Typically two bearings on a drive shaft.
Gear ratio (pulley : motor)
Example: 10 means pulley torque is 10x motor torque.
Overall efficiency
Gearbox + coupling + belt path efficiency.
