Why an energy efficient motor is needed for any application?

Energy efficient motors use less electricity, run cooler, and often last longer than NEMA (National Electrical Manufacturers Association) B motors of the same size. … Energy efficient electric motors utilize improved motor design and high quality materials to reduce motor losses, therefore improving motor efficiency.

What is the necessity of energy efficient motors?

There are number of benefits which Energy-‐efficient motors possess. Energy efficient motors have features with improved manufacturing techniques and superior materials, it usually have longer bearing lives, higher service factors as well as lower waste heat output, less vibration, all of which increase reliability.

What are the requirements of energy efficient motors?

Load Variation

Most electric motors are designed to run at 50 per cent to 100 per cent of rated load, the maximum efficiency is achieved usually near 75 per cent of rated load. Thus, a 10-hp motor has an acceptable load range of 5 to 10 hp with maximum efficiency is at 7.5 hp.
