Going beyond IE5 -the 'gold' standard in compressor electric motor efficiency

摘要

As part of a concerted effort worldwide to reduce energy consumption, CO2 emissions and the impact of industrial operations on the environment, regulatory authorities have introduced legislation to encourage the manufacture of higher efficiency electric motors. Atlas Copco has not only taken these efficiency considerations on board but has gone even further to achieve the highest efficiency class -equivalent to IE5 - in its compressor technology. The European Commission has passed regulations that stipulate the minimum efficiency levels for LV electric motors produced and supplied within Europe. The substance of the regulations focuses on the energy usage and energy efficiency of induction motors used in industrial environments. In the UK, EU Regulation 64072009 and the 04/2014 supplement defines the minimum efficiency levels for induction motors. To aid conformity to the regulations, the International Electrotechnical Commission (IEC) prepares and publishes international standards for all electrical, electronic and related technologies. The scope of these standards defines efficiency levels in tandem with advances in motor technology developments and innovation.
