(Main)Rotating electrical machines - Part 2-3: Specific test methods for determining losses and efficiency of converter-fed AC motors
Rotating electrical machines - Part 2-3: Specific test methods for determining losses and efficiency of converter-fed AC motors
IEC 60034-2-3:2024 specifies test methods and an interpolation procedure for determining losses and efficiencies of converter-fed motors. The motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800‑9‑2. This document also specifies procedures to determine motor losses at any load point (torque, speed) within the constant flux range (constant torque range, base speed range), the field weakening range and the overload range based on determination of losses at seven standardized load points. This procedure is applicable to any variable speed AC motor (induction and synchronous) rated according to IEC 60034-1 for operation on a variable frequency and variable voltage power supply. This second edition cancels and replaces the first edition of IEC 60034-2-3 published in 2020. This edition includes the following significant technical changes with respect to the previous edition: - Harmonization of requirements and procedures with IEC 60034-2-1. - Extension of the interpolation procedure to the field weakening range.

Machines électriques tournantes - Partie 2-3: Méthodes d'essai spécifiques pour la détermination des pertes et du rendement des moteurs à courant alternatif alimentés par convertisseur
L'IEC 60034-2-3:2024 spécifie les méthodes d'essai et la procédure d'interpolation relatives à la détermination des pertes et des rendements des moteurs alimentés par convertisseur. Le moteur est alors considéré comme faisant partie intégrante d'un système d'entraînement électrique de puissance (PDS) à fréquence variable, comme cela est défini dans l'IEC 61800‑9‑2. Le présent document spécifie également des procédures de détermination des pertes du moteur en tout point de charge (couple, vitesse) dans la plage de flux constants (plage de couples constants, plage de vitesses de base), la plage d'affaiblissement du champ et la plage de surcharge à partir de la détermination des pertes au niveau de sept points de charge normalisés. Cette procédure s'applique à tout moteur à courant alternatif à vitesse variable (à induction et synchrone) assigné selon l'IEC 60034-1 pour un fonctionnement à fréquence variable et alimenté en tension variable. Cette deuxième édition annule et remplace la première édition de l'IEC 60034-2-3 parue en 2020. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - Harmonisation des exigences et procédures avec l'IEC 60034-2-1; - Extension de la procédure d'interpolation à la plage d'affaiblissement du champ.
Električni rotacijski stroji - 2-3. del: Posebne preskusne metode za ugotaljanje izgub in izkoristkov izmeničnih motorjev napajanih s pretvorniki (IEC 60034-2-3:2024)
Standard IEC 60034-2-3:2024 določa preskusne metode in postopek interpolacije za ugotavljanje izgub in izkoristkov motorjev, napajanih s pretvorniki. Motor je del pogonskega sistema s spremenljivo frekvenco (PDS), ki je opredeljen v standardu IEC 61800‑9‑2. Ta dokument določa tudi postopke za ugotavljanje izgub motorja pri kateri koli točki obremenitve (navor, hitrost) znotraj območja stalnega pretoka (območje stalnega navora, območje osnovne hitrosti), območja oslabitve polja in območja preobremenitve na podlagi ugotavljanja izgub pri sedmih standardiziranih točkah obremenitve. Ta postopek se uporablja za kateri koli izmenični (AC) motor s spremenljivo hitrostjo (indukcijski in sinhronski), ocenjen v skladu s standardom IEC 60034-1 za delovanje v napajalniku s spremenljivo frekvenco in napetostjo. Druga izdaja razveljavlja in nadomešča prvo izdajo standarda IEC 60034-2-3, objavljeno leta 2020. Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
– zahteve in postopki so bili usklajeni s standardom IEC 60034-2-1;
– postopek interpolacije je bil razširjen na območje oslabitve polja.
