Motor Matching Yield at 68% target motor-matching pass rate: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target motor-matching pass rate to 68%, then walk the calculation through step by step. Estimate motor matching yield for uav and drone manufacturing using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Motor sets meeting Kv/thrust match spec: 8 count (held at the documented default)
  • Total motor sets screened: 250 count (held at the documented default)
  • Target motor-matching pass rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Motor matching yield rate = motor matching yield count ÷ total motor matching yield population × 100.
  • Motor matching yield rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Motor matching yield gap to target works out to 64.8 points at these inputs.
  • Motor matching yield count works out to 8 count at these inputs.
  • Total motor matching yield population works out to 250 count at these inputs.

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 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target motor-matching pass rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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: 64.8 points
  • Motor matching yield count: 8 count
  • Total motor matching yield population: 250 count
