Annotation

IEC 60034-12:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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.
