⚙️ Motor & Drive Optimizer

Calculate the minimal standard motor size (HP/kW) and estimate efficiency based on fan mechanical power.

1. Required Mechanical Power & Efficiency

Fan Mechanical Input Power (Pmech)

* This is the power delivered to the fan shaft (from other calculators).

Target Efficiency Class (IEC Standard) * Higher class = lower running cost.

Nominal Motor RPM (N_rated) * Used for frame size reference.

Motor/Drive Type * Affects overall system efficiency and control.
