A REVIEW ON EFFICIENCY OF ENERGY EFFICIENT MOTOR STANDARDS

Abstract

It is proved that of all electricity generated worldwide, about 30-40% is consumed by Industrial electric motors. The electric motor system uses about 70% of the electrical energy which is consumed by the industries in which induction motor observes major part. Now a day we go for Energy efficient electric motors, which not only saves the electricity bill but also reduces the emission of greenhouse gases. Many countries in the world started to pay their attention in establishing appliance standards as Europe and North America introduced. There is no single methodology to establish standards for electric motor as the methodology for electric motor efficiency standards is still in developing stage. This paper reviews the recently developed standard IEC 60034-30:2008 which is intended to harmonize efficiency classes throughout the world. It also includes the initiatives for standardization progress of the three-phase asynchronous motor efficiency levels in the main world regions, highlighting the Indian scenario for adopting the standard IEC 60034-30:2008.
