Motor Winding Labor at 7.2% setup and handling allowance: a worked example

Suppose setup and handling allowance falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate labor time for stator or motor winding work using the required winding count, observed completion rate, and a setup or handling allowance.

The inputs for this scenario

  • Winding operations required: 120 operations (held at the documented default)
  • Winding completion rate: 12 operations / min (held at the documented default)
  • Setup and handling 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 motor winding labor time = winding workload รท winding completion rate.
  • Required motor winding labor time works out to 10.72 min at these inputs, and this is the headline figure for the scenario.
  • Base winding time works out to 10 min at these inputs.
  • Winding allowance applied works out to 7.2 % at these inputs.
  • Winding completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where setup and handling allowance sits at 10% and the headline result is 11 min, this scenario comes in 2.55% below the baseline at 10.72 min.
  • It computes required winding labor time as the base time (operations divided by completion rate) multiplied by a setup-and-handling allowance factor. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Required motor winding labor time: 10.72 min (headline result)
  • Base winding time: 10 min
  • Winding allowance applied: 7.2 %
  • Winding completion rate: 12 pieces / min
