Motor Efficiency Calculator

Calculate motor efficiency η = P_out/P_in × 100%. IE efficiency classes: IE1 (standard), IE2 (high), IE3 (premium), IE4 (super premium). Energy savings from upgrading motor efficiency class. Annual operating cost.

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 motor efficiency η = P_out/P_in × 100%. IE efficiency classes: IE1 (standard), IE2 (high), IE3 (premium), IE4 (super premium). Energy savings from upgrading motor efficiency class. Annual operating cost

Each component has a specific meaning:

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

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

How to Use

Enter the upgrading motor efficiency class for the patient or scenario you are assessing. Calculate motor efficiency η = P_out/P_in × 100%. IE efficiency classes: IE1 (standard), IE2 (high), IE3 (premium), IE4 (super premium). Energy savings from upgrading motor efficiency class. Annual operating cost. Use the motor efficiency result to inform your clinical assessment.
