Motors & Motion Calculator

Conveyor Motor Sizing Calculator

Estimate conveyor drive force, roller torque, roller RPM, and motor power for basic horizontal conveyor applications using load, speed, roller diameter, friction, efficiency, and safety factor.

Good starting use case: estimate a first-pass conveyor motor requirement for a simple horizontal application before moving into gearbox ratio, service factor, acceleration, and detailed mechanical review.

Estimate Conveyor Force, Torque, RPM, and Motor Power

Estimate conveyor drive force, torque, roller RPM, and motor power for basic horizontal conveyor applications. If you are still determining throughput or required line rate, start with the conveyor speed calculator before sizing the motor.

This calculator is useful for early conveyor sizing in automation systems, material handling equipment, transfer conveyors, and basic machine design.

This free conveyor motor sizing calculator helps estimate required drive force, torque, and power for simple horizontal conveyors using load weight, conveyor speed, roller diameter, friction factor, efficiency, and safety factor.

For pneumatic-driven conveyors or hybrid systems, verify available actuator force using the pneumatic force calculator.

What this calculator gives you

  • Required conveyor force
  • Required roller torque
  • Drive roller RPM
  • Power in W, kW, and hp

Where this helps

Useful for early conveyor drive sizing, transfer system concepts, machine build review, and checking whether a proposed motor and reducer are even in the right range.

Common next checks

  • Gearbox ratio selection
  • Motor torque margin
  • Startup and acceleration loads
  • Incline or side-load effects
  • Service factor and thermal limits

How to Use This Calculator

1. Confirm conveyor speed

Start with required line speed, throughput, or transfer time. Use the conveyor speed calculator first if the speed target is not locked in.

2. Estimate moving load and friction

Enter the load weight and a realistic friction factor for the conveyor style, bearings, belt, rollers, and product contact.

3. Calculate force, torque, and power

Use the output to see if the motor and drive roller are in the right range before selecting a reducer or motor frame.

4. Verify real startup conditions

Check startup torque, acceleration time, duty cycle, service factor, incline load, and gearbox output torque before committing to hardware.

Estimate Conveyor Force, Torque, and Power

Enter load, conveyor speed, roller diameter, friction factor, mechanical efficiency, and safety factor. The calculator estimates required force, torque, drive roller speed, and motor power.

Enter values and press Calculate.

This is a starting estimate — real systems often require adjustment based on startup load, gearbox selection, duty cycle, acceleration, and mechanical losses.

Do Not Stop at Steady-State Power

The calculated power is a first-pass estimate for a basic horizontal conveyor. Real conveyor systems often need additional review for acceleration torque, repeated starts and stops, duty cycle, product buildup, belt tension, bearing drag, reducer efficiency, and overload conditions.

A motor that looks acceptable on steady-state power can still fail if the conveyor has high starting load, sticky product, poor bearings, incline sections, indexing motion, or frequent start-stop cycles.

This calculator is intended for basic horizontal conveyor estimates. It does not account for incline angle, belt type, start-up surge, multiple rollers, belt mass, acceleration requirements, or detailed bearing and drive losses.

Continue Your Conveyor Drive Design

After sizing motor requirements, the next step is usually checking conveyor speed targets, gearbox ratio, actual motor torque margin, and whether startup or acceleration loads are significantly higher than steady-state demand.

This matters even more on heavier conveyors, longer lines, index conveyors, and systems with variable speed control or repeated starts and stops.

Still unsure if this motor sizing will hold up in the real system?
