Assumptions

  • Motors arranged in regular polygon (equal spacing)
  • Frame diagonal = motor-to-motor distance
  • Disk loading: Low (<50) = efficient, High (>100) = review needed

When This Estimate Breaks Down

  • H-frame or stretched-X layouts need custom calculation
  • High disk loading may cause efficiency loss and noise
  • Frame class matching is for reference only
