Industrial Motor Efficiency Upgrade Savings Calculator

Calculate annual energy savings from upgrading to NEMA Premium Efficiency (IE3) or IE4 motors. Model operating hours, load factor, and motor size.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate annual energy savings from upgrading to NEMA Premium Efficiency (IE3) or IE4 motors. Model operating hours, load factor, and motor size

Each component has a specific meaning:

  • Upgrading — The upgrading recorded for the patient or scenario being assessed.

Note: Interpret the motor efficiency savings result against the clinical thresholds and context described above.

How to Use

Enter the upgrading for the patient or scenario you are assessing. Calculate annual energy savings from upgrading to NEMA Premium Efficiency (IE3) or IE4 motors. Model operating hours, load factor, and motor size. Use the motor efficiency savings result to inform your clinical assessment.
