Stator Winding Labor at 12% setup, lacing, and lead-connection allowance: a worked example

This scenario runs the stator winding labor calculation on the strong side: 12% setup, lacing, and lead-connection allowance, with every other input held at its documented default. Use it when a stator winding or rewind job is going on next week's schedule and you need an honest labor-hour estimate.

The inputs for this scenario

  • Stators to wind this run: 120 stators (unchanged)
  • Winding throughput per coil-winding station: 12 stators / min (unchanged)
  • Setup, lacing, and lead-connection allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base stator winding time = stators to wind รท winding rate per winder) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required stator winding time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base stator winding time.
  • At this operating point the engine returns 12 % for setup and lacing allowance applied.
  • At this operating point the engine returns 12 pieces / min for winding rate per winder.

How this compares with the baseline

  • Against the tool's baseline example, where setup, lacing, and lead-connection allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it when planning a winding-cell shift, quoting a rewind contract, or checking whether a winding station can clear a batch before the balancing line needs it. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Required stator winding time: 11.2 hr (headline result)
  • Base stator winding time: 10 hr
  • Setup and lacing allowance applied: 12 %
  • Winding rate per winder: 12 pieces / min

Run it with your numbers

  • Every input above is editable in the live Stator Winding Labor calculator, which recalculates instantly and can be shared with the inputs intact.
