How to reduce energy consumption for motors?

Hi,

I'm a student, and i have been given a task during my internship, which is a study of the energy consumption of all the motors inside the enterprise, in order to try and come up with a plan to reduce their consumption.

I've done some research, and was able to determine that in order to do so, a speed control of motors so as to adapt it to the load is necessary, as well as the optimisation of their efficiency and regular maintenance.

The problem is that i can't figure out a way to start working on this project, so what i need to know is how to be able to give a solution through analyzing the motors' energy consumption ? and what are the points i need to focus on ? or the motors i need to target ? and which strategy is to adopt in order to be able to succeed in this task ?

And if there are more ideas on the solutions to reduce motors' energy consumption, please feel free to enlighten me.

Thank you in advance.

Hi Ray,

I have an article from IEEE about Reduction of electric energy consumption in induction motor drives by setting supply voltage.

Hope it helps,

it seems i can't access the website, can you email the artical to me or maybe put it on another file hoster and give me the link ?

Energy efficient motors, new technologies, and best practices can reduce energy consumption by 30 to 50 percent, according to the U.S. DOE. Manufacturers should evaluate motor selection based on life-cycle costs, rather than initial price. NEMA Premium® efficient motors and system efficiency upgrades help maximize potential gains.

In situations where a repair makes more economic sense than a motor replacement you must not forget its potential effect on the motor’s efficiency and your total cost of ownership.
