Rotating electrical machines - Part 30-3: Efficiency classes of high voltage AC motors (IE-code)

IEC 60034-30-3:2024 specifies efficiency classes for fixed-speed three-phase high-voltage cage induction motors in accordance with IEC 60034-1 that - have a rated voltage exceeding 1 000 V, but not exceeding 11 kV; - have a rated power from 200 kW to 2 000 kW; This document provides the global harmonization of energy-efficiency classes of three-phase cage induction motors with rated voltage above 1 000 V that are rated for direct online starting and fixed-speed operation at a 50 Hz or 60 Hz supply with sinusoidal voltage.

Machines électriques tournantes - Partie 30-3: Classes de rendement des moteurs à courant alternatif à haute tension (code IE)

IEC 60034-30-3:2024 spécifie les classes de rendement pour les moteurs triphasés à induction à cage à haute tension et à vitesse fixe conformément à l'IEC 60034-1, qui - ont une tension assignée supérieure à 1 000 V, mais qui ne dépasse pas 11 kV; - ont une puissance assignée comprise entre 200 kW et 2 000 kW; Le présent document prévoit l'harmonisation globale des classes de rendement énergétique des moteurs triphasés à induction à cage dont la tension assignée est supérieure à 1 000 V, qui sont assignés pour démarrer directement sur réseau et fonctionner à vitesse fixe sur une alimentation de 50 Hz ou 60 Hz avec une tension sinusoïdale.
