Stator Winding Capacity at 65% expected winding machine uptime: a worked example

Suppose expected winding machine uptime falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate good stator winding output from stators per cycle, planned cycles, uptime, and first-pass yield.

The inputs for this scenario

  • Stators completed per winding cycle: 4 stators / cycle (held at the documented default)
  • Planned winding cycles: 480 cycles (held at the documented default)
  • Expected winding machine uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected winding first-pass yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross stator winding capacity = stators completed per cycle × planned winding cycles.
  • Good stator winding capacity works out to 1,211 stators at these inputs, and this is the headline figure for the scenario.
  • Gross stator winding capacity works out to 1,920 stators at these inputs.
  • Stator winding downtime loss works out to 672 stators at these inputs.
  • Stator winding yield loss works out to 37.44 stators at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected winding machine uptime sits at 90% and the headline result is 1,676 stators, this scenario comes in 27.78% below the baseline at 1,211 stators.
  • It computes gross and good stator winding capacity and splits the shortfall into downtime loss and yield loss. 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

  • Good stator winding capacity: 1,211 stators (headline result)
  • Gross stator winding capacity: 1,920 stators
  • Stator winding downtime loss: 672 stators
  • Stator winding yield loss: 37.44 stators
