1. ABB original high effiency motors 2. Size:56-355, from 0.06~250Kw 3. IEC60034-30,2008 4. Temperature rise : Class B
ABB electric motors
Low voltage general performance IE2 high effiency motors
Efficiency values are given according to IEC 60034-2-1; 2007.Please note that the values are not comparable without knowing the testing method.ABB has calculated the efficiency values according to indirect method, stray load losses (additional losses) determined from measuring.Is / IN = Starting currentTl / TN = Locked rotor torqueTb / TN = Breakdown torque1) Temperature rise class FIE-class concerns motors from 0.75 kW to 375 kW.
