Motor Matching Yield at 99% target motor-matching pass rate: a worked example

What does the result look like when target motor-matching pass rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when motor matching yield in uav and drone manufacturing needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Motor sets meeting Kv/thrust match spec: 8 count (unchanged)
  • Total motor sets screened: 250 count (unchanged)
  • Target motor-matching pass rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Motor matching yield rate = motor matching yield count ÷ total motor matching yield population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for motor matching yield rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for motor matching yield gap to target.
  • At this operating point the engine returns 8 count for motor matching yield count.
  • At this operating point the engine returns 250 count for total motor matching yield population.

How this compares with the baseline

  • Against the tool's baseline example, where target motor-matching pass rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target motor-matching pass rate is genuinely sustained, not just peaked for a shift. It reports a static pass rate from the counts entered and does not distinguish which parameter (Kv, thrust, current) drove the failures, so pair it with parameter-level data before acting.

Results at a glance

  • Motor matching yield rate: 3.2 % (headline result)
  • Motor matching yield gap to target: 95.8 points
  • Motor matching yield count: 8 count
  • Total motor matching yield population: 250 count
