The paper presents the results of a research project whose aim was the investigation of the efficiency improvement of industrial three-phase induction motors when high quality electrical steel is adopted in combination with die cast copper rotor cage, in order to define the design strategies; to verify the actual efficiency improvements; to verify the arrangement of the motors respect to the European Classification Scheme (EC-CEMEP). The results are related to the cheapest design strategies when “premium steel” and copper rotor cage are used instead of standard steel and aluminum cage, with standard and higher stack length. The considered motor sizes are 3 and 7.5 kW, 4 pole, 50 Hz, 400 V, TEFC.

Abstract

The paper presents the results of a research project whose aim was the investigation of the efficiency improvement of industrial three-phase induction motors when high quality electrical steel is adopted in combination with die cast copper rotor cage, in order to define the design strategies; to verify the actual efficiency improvements; to verify the arrangement of the motors respect to the European Classification Scheme (EC-CEMEP). The results are related to the cheapest design strategies when “premium steel” and copper rotor cage are used instead of standard steel and aluminum cage, with standard and higher stack length. The considered motor sizes are 3 and 7.5 kW, 4 pole, 50 Hz, 400 V, TEFC.
