Valori Limite di Efficienza - IEC 60034-30-1:2014 (Basato su IEC 60034-2-1:2015)

La tabella seguente riporta i valori limite di efficienza energetica per motori elettrici secondo lo standard internazionale IEC 60034-30-1, edizione marzo 2014, calcolati in conformità alla norma IEC 60034-2-1:2015. I dati si riferiscono al funzionamento a 50 Hz e rappresentano un riferimento fondamentale per la classificazione IE (International Efficiency) dei motori asincroni a induzione trifase. Uno strumento utile per tecnici, progettisti e professionisti del settore energetico e industriale
