Potting Material Usage with potting compound dispense rate of 6 units / hr: a worked example

This worked example runs the potting material usage numbers for a tougher week than the baseline: potting compound dispense rate of 6 units / hr instead of the typical 12 units / hr. Estimate potting or encapsulant consumption and cost for power modules, gate drivers, coils, sensors, converters, and motor electronics.

The inputs for this scenario

  • Potting compound dispense rate: 6 units / hr (the input this scenario stresses; the baseline uses 12)
  • Potting line runtime: 8 hr (held at the documented default)
  • Potting compound cost: 3.5 $ / unit (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Potting material consumed = potting dispense or use rate × potting production runtime.
  • Potting material run cost works out to 168 $ at these inputs, and this is the headline figure for the scenario.
  • Potting material consumed works out to 48 units at these inputs.
  • Potting production runtime works out to 8 hr at these inputs.
  • Potting material cost works out to 3.5 $ / unit at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where potting compound dispense rate sits at 12 units / hr and the headline result is 336 $, this scenario comes in 50% below the baseline at 168 $.
  • Use it to budget potting resin for a job, plan material reorders, or cost the encapsulation step of a drive or motor. 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

  • Potting material run cost: 168 $ (headline result)
  • Potting material consumed: 48 units
  • Potting production runtime: 8 hr
  • Potting material cost: 3.5 $ / unit
