This Standard applies to three-phase cage induction motors with ratings from 0.73 kW and up to but not including 185 kW. The scope covers motors of rated voltages up to 1100 V a.c.NOTE: This range includes motors with ratings of 1 hp and 1 CV/PS (French/German or metric horsepower).This Standard specifies the minimum efficiency values that a motor shall meet, and also the minimum efficiency values that a motor shall meet in order to be designated ‘high efficiency’. Two methods of measurement are prescribed (Method A and Method B) for determination of efficiency. See Sections 2 and 3 for details. Only one method need be applied.NOTES:1 Minimum efficiency and high efficiency values covered by this Standard are categorized based on the regulatory dates.2 In New Zealand, the MEPS covered by this Standard will be addressed by an amendment to this Standard and a subsequent gazette notice.
