Report on International Efficiency Efficiency Classes for ...

1of 13 Report on Study on International Efficiency (IE) Efficiency Classes for Low Voltage AC Motors Executive Summary In Hong Kong, the Code of Practice for energy Efficiency of Building Services Installation (Code of Practice) specifies the minimum motor Efficiency for single-speed three-phase totally enclosed motor . These requirements serve to determine the baseline energy performance on motor . Internationally, there is a standard which stipulates the energy Efficiency of low voltage AC motors, namely the International Efficiency (IE).

Motors that are completely integrated into a machine, such as a pump, fan and compressor, and frequency-converters that cannot be tested for its efficiency individually shall be excluded from the IE standard; Brake motors, which is an integral part of the inner motor construction, cannot be
