Analysis of electrical motors load factors and energy savings in an Indian cement industry

Electric motors consume in between 30 and 80 of the total industrial energy use for few selected countries around the world. It was identified that many motors are operated under loaded conditions. In some cases, motors are operated even at 3-16 of their full loads. These low loads can be optimized...
