Motor Efficiency Calculator
Calculate electric motor efficiency, energy consumption, and potential savings. Understand how motor type, load, and operating hours affect your energy costs.
Step 1: Motor Specifications
Understanding Motor Efficiency
Motor efficiency is the ratio of mechanical power output to electrical power input, expressed as a percentage. Higher efficiency motors reduce energy waste and operating costs.
Step 2: Operating Conditions
About Motor Load
Motor load affects efficiency. Motors typically operate most efficiently at 75-100% load. Underloading (below 50%) significantly reduces efficiency and increases energy costs.

Energy Consumption Analysis
Motor Efficiency Formula
Efficiency (%) = (Mechanical Power Output ÷ Electrical Power Input) × 100
Motor efficiency is calculated by dividing mechanical output power by electrical input power. Energy savings from efficient motors depend on operating hours, load, and electricity cost.
