Stator Winding Labor at 7.2% setup, lacing, and lead-connection allowance: a worked example

This worked example runs the stator winding labor numbers for a tougher week than the baseline: 7.2% setup, lacing, and lead-connection allowance instead of the typical 10%. Estimate the labor hours to wind motor and generator stators so winding teams can plan crew time, schedule the work, and confirm the build or rewind fits the available shift.

The inputs for this scenario

  • Stators to wind this run: 120 stators (held at the documented default)
  • Winding throughput per coil-winding station: 12 stators / min (held at the documented default)
  • Setup, lacing, and lead-connection allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base stator winding time = stators to wind รท winding rate per winder.
  • Required stator winding time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base stator winding time works out to 10 hr at these inputs.
  • Setup and lacing allowance applied works out to 7.2 % at these inputs.
  • Winding rate per winder works out to 12 pieces / min at these inputs.

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 2.55% below the baseline at 10.72 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. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Required stator winding time: 10.72 hr (headline result)
  • Base stator winding time: 10 hr
  • Setup and lacing allowance applied: 7.2 %
  • Winding rate per winder: 12 pieces / min
