Motor Winding Labor at 12% setup and handling allowance: a worked example

What does the result look like when setup and handling allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when planning coil insertion, winding, lacing, lead termination, inspection, or repair labor for motor production or service work.

The inputs for this scenario

  • Winding operations required: 120 operations (unchanged)
  • Winding completion rate: 12 operations / min (unchanged)
  • Setup and handling allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base motor winding labor time = winding workload ÷ winding completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 min for required motor winding labor time, the number this scenario is built around.
  • At this operating point the engine returns 10 min for base winding time.
  • At this operating point the engine returns 12 % for winding allowance applied.
  • At this operating point the engine returns 12 pieces / min for winding completion rate.

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 1.82% above the baseline at 11.2 min.
  • A figure at this level is achievable when setup and handling allowance is genuinely sustained, not just peaked for a shift. A single completion rate assumes uniform coil geometry — mixed pole counts or wire gauges within the batch will pull the effective rate away from the entered value.

Results at a glance

  • Required motor winding labor time: 11.2 min (headline result)
  • Base winding time: 10 min
  • Winding allowance applied: 12 %
  • Winding completion rate: 12 pieces / min
