Motor Test Capacity at 99% motor test station uptime: a worked example

What does the result look like when motor test station uptime reaches 99%? The full calculation is worked below with real intermediate numbers. an e-bike or scooter assembly line needs to confirm motor test capacity before committing a daily or weekly production schedule

The inputs for this scenario

  • Motors tested per cycle: 4 motors / cycle (unchanged)
  • Available motor test cycles: 180 cycles (unchanged)
  • Motor test station uptime: 99 % (raised for this scenario; the documented default is 92)
  • Motor first-pass test yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross motor test slots = motors tested per cycle × available motor test cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 691 motors for accepted motor test capacity, the number this scenario is built around.
  • At this operating point the engine returns 720 motors for gross motor test slots.
  • At this operating point the engine returns 7.2 motors for motor test downtime loss.
  • At this operating point the engine returns 21.38 motors for motor test yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where motor test station uptime sits at 92% and the headline result is 643 motors, this scenario comes in 7.61% above the baseline at 691 motors.
  • A figure at this level is achievable when motor test station uptime is genuinely sustained, not just peaked for a shift. It models first-pass yield only; motors that pass on retest are not added back, so true accepted capacity may be slightly higher if you rework and retest failures.

Results at a glance

  • Accepted motor test capacity: 691 motors (headline result)
  • Gross motor test slots: 720 motors
  • Motor test downtime loss: 7.2 motors
  • Motor test yield loss: 21.38 motors
