Winding Machine Output at 65% winding process efficiency: a worked example

Suppose winding process efficiency falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Winding Machine Output converts coils completed and hours run into an hourly throughput, then derates it by process efficiency to give a rate you can plan against.

The inputs for this scenario

  • Coils completed in the run: 1,200 units (held at the documented default)
  • Machine runtime: 8 hr (held at the documented default)
  • Winding process efficiency: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw winding machine output = completed output รท runtime.
  • Effective throughput works out to 97.5 units / hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 150 units / hr at these inputs.
  • Efficiency works out to 65 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where winding process efficiency sits at 90% and the headline result is 135 units / hr, this scenario comes in 27.78% below the baseline at 97.5 units / hr.
  • It computes raw throughput as coils divided by runtime, then multiplies by efficiency to give an effective hourly winding rate. 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

  • Effective throughput: 97.5 units / hr (headline result)
  • Raw throughput: 150 units / hr
  • Efficiency: 65 %
  • Runtime: 8 hr
