General Purpose 3-phase Induction MotorsEFFICIENCY OF MOTORSCantoni Motor has in offer general purpose standard efficiency motors of (2) Sg, Sh series which fulfil IE1class requirements according to the IEC 60034-30 standard.The present catalogue describes the electric motors which belong to the efficiency class IE2 (High Efficiency)and motors excluded from the IEC 60034-30 standard (motors with 2p = 8, 10, 12 and with rated output below0.75kW and above 375kW).Comparison between the efficiency of Cantoni Group motors (for example 2p=4)and efficiency class IE1/IE2 requirements according to the IEC 60034-30.94Efficiency [%]8678700,1 1 10 100 400P N [kW]IE2IE1High Efficiency (Cantoni)Standard (Cantoni)The efficiency class system specified under IEC 60034-30 is valid for low voltage three phasesquirrel cage induction motors with the following specifications:· Rated voltage up to 1.000 V· Rated output between 0.75 kW and 375 kW· Either 2, 4 or 6 poles· Rated on the basis of continuous duty (S1) or intermittent periodic duty (S3) withcyclic duration factor of 80% or higher· Capable of operating direct on-line· Rated for operating conditions in accordance with IEC 60034-1 (temperature,installation altitude, etc.)Motors with flanges, feet and/or shafts with mechanical dimensions different from IEC 60072-1are also covered by this standard.06
