Determining Electric Motor Load and Efficiency

Determining Electric Motor Load and Efficiency

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 75 hp A motor ’s efficiency tends to decrease dramatically below about 50% load However, the range of good efficiency varies with individual motors and tends to
