Rotating electrical machines - Part 2-1: Standard methods for determining losses and efficiency from tests (excluding machines for traction vehicles)

IEC 60034-2-1:2024 is available as IEC 60034-2-1:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60034-2-1:2024 is intended to establish methods of determining efficiencies from tests, and also to specify methods of obtaining specific losses. This document applies to DC machines and to AC synchronous and induction machines of all sizes within the scope of IEC 60034-1 rated for mains operation. These methods may be applied to other types of machines such as rotary converters, AC commutator motors and single-phase induction motors. This third edition cancels and replaces the second edition of IEC 60034-2-1 published in 2014. This edition includes the following significant technical changes with respect to the previous edition:
- Harmonization of layout and requirements with IEC 60034-2-2 and IEC 60034-2-3.

Drehende elektrische Maschinen - Teil 2-1: Standardverfahren zur Bestimmung der Verluste und des Wirkungsgrades aus Prüfungen (ausgenommen Maschinen für Schienen- und Straßenfahrzeuge)

Machines électriques tournantes - Partie 2-1: Méthodes normalisées pour la détermination des pertes et du rendement à partir d'essais (à l'exclusion des machines pour véhicules de traction)

IEC 60034-2-1:2024 est disponible sous forme de IEC 60034-2-1:2024 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L'IEC 60034-2-1:2024 a pour objet de définir les méthodes de détermination du rendement à partir d'essais et également de spécifier les méthodes qui permettent de déterminer des pertes spécifiques. Le présent document s'applique aux machines à courant continu ainsi qu'aux machines à courant alternatif, synchrones et à induction, de toutes dimensions, qui entrent dans le domaine d'application de l'IEC 60034-1 et assignées pour un fonctionnement sur secteur. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Harmonisation de la disposition et des procédures avec l'IEC 60034-2-2 et l'IEC 60034-2-3.
