Step-by-step calculation
Formula
Belt speed (m/min) = π × Roller diameter (m) × Roller rpm
Roller rpm = Belt speed ÷ (π × D); Motor rpm = Roller rpm × Gearbox ratio
Belt speed from motor = π × D × (Motor rpm ÷ Ratio)Worked example
Calculated with the default values shown in the form.
Technical notes
- Use the effective roller diameter including lagging or belt thickness.
- With a VFD, set the output frequency to the motor rpm needed (rpm ≈ 120 × Hz ÷ poles).
