A Study of the World's Minimum Energy Performance Standard for Electric Motors and Drives

Abstract

It has been proven that industrial electric motors consume 30-40% of all electricity generated worldwide. The electric motor system consumes roughly 70% of the electrical power spent by industrial segment in which induction motors play a significant role. Nowadays, we prefer energy-efficient electric motors, which not only save money on power but also minimize greenhouse gas emissions. As a result, regulatory plans are in place in the EU, as well as the USA, China, and other countries, requiring new installations to comply with gradually increasing efficiency requirements. This study examines the IEC/EN 60034-30-1: 2014 Standard, which aims to standardize efficiency classes all around the world. This paper also discusses International norms and domestic legislation for the high efficiency electric motors and the systems that power them, as well as the universal trend of electrical motors meeting minimum energy performance standards (MEPS), with a focus on the new EU 2019/1781, amendment (EU) 2021/341 for electrical motors and drives with varying speeds.
