  • Determining Electric Motor Load and Efficiency

    2014-4-28u2002·u2002Reasons to Determine Motor Loading Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor 's efficiency tends to decrease dramatically below about 50% load.
