Rotating electrical machines - Part 12: Starting performance of single-speed three-phase cage induction motors

IEC 60034-12:2024 is available as IEC 60034-12:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60034-12:2024 specifies the parameters for eight designs of starting performance of single-speed three-phase 50 Hz or 60 Hz cage induction motors in accordance with IEC 60034‑1 that:
- have a rated voltage up to 1 000 V;
- are intended for direct-on-line or star-delta starting;
- are rated on the basis of duty type S1;
- are constructed to any degree of protection as defined in IEC 60034-5 and explosion protection.
This document also applies to dual voltage motors provided that the flux saturation level is the same for both voltages. This fourth edition cancels and replaces the third edition published in 2016. Aligned with the requirements for explosion protected motors from TC31 WG27
- new clause on methods for measuring locked-rotor current and torque;
- new informative annex on the general current and torque characteristics with locked rotor;
- new informative annex on correction of voltage and frequency;
- aligned with the requirements for explosion protected motors from TC31 WG27.

Machines électriques tournantes - Partie 12: Caractéristiques de démarrage des moteurs triphasés à induction à cage à une seule vitesse

IEC 60034-12:2024 est disponible sous forme de IEC 60034-12:2024 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L'IEC 60034-12:2024 spécifie les paramètres de huit conceptions de caractéristiques de démarrage de moteurs triphasés à induction à cage à une seule vitesse fonctionnant à 50 Hz ou 60 Hz conformes à l'IEC 60034-1, qui:
- ont des tensions assignées jusqu'à 1 000 V;
- sont prévus pour démarrage direct ou étoile-triangle;
- sont dimensionnés pour le service type S1;
- peuvent avoir n'importe quel degré de protection tel qu'il est défini dans l'IEC 60034-5 et incluant les protections contre les explosions.
Ce document s'applique également aux moteurs bitension à condition que le niveau de saturation du flux soit le même aux deux tensions. Cette quatrième édition annule et remplace la troisième édition parue en 2016. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- aligné sur les exigences du CE 31, GT 27, concernant les moteurs antidéflagrants;
- nouvel article relatif aux méthodes de mesure du courant et du couple à rotor bloqué;
- nouvelle annexe informative relative aux caractéristiques générales de courant et de couple à rotor bloqué;
- nouvelle annexe informative relative à la correction de la tension et de la fréquence.
