Mechanical Efficiency

Efficiency and lost power from mechanical input and output power.

Mechanical & Motion

Efficiency and lost power from mechanical input and output power.

App id: MECH-18. Reference version 1.0.

How to fill it

Fill the inputs. The tool shows the outputs.

On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.

Formula

η = Pout / Pin

Diagnose

Observations are context. They do not pass or fail a structure. See Diagnose.

WhenObservationSeverity
Efficiency > 1.02Efficiency above 100%warning

Efficiency < 0.5Low mechanical efficiencycaution

Assumptions

  • Efficiency above 100% is reported rather than clamped — it is a sanity check.

Provenance

  • Steady-state power ratio at the same operating condition.
