IEC 60034-12:20 24作为IEC 60034-12:20 24 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60034-12:20 24规定了根据IEC 60034的单速三相50 Hz或60 Hz笼型感应电动机启动性能的八种设计？1那个: -具有高达1000V的额定电压； -用于直接在线或星形-三角形起动； -根据职责类型S1进行评级； -具有IEC 60034-5中定义的任何防护等级和防爆等级。 本文件也适用于双电压电机，前提是两种电压的磁通饱和水平相同。这第四版取消并取代了2016年出版的第三版。符合TC31 WG27对防爆电机的要求 -关于测量锁定转子电流和扭矩的方法的新条款； -关于锁定转子的一般电流和转矩特性的新信息附件； -关于电压和频率校正的新信息附件； -符合TC31 WG27对防爆电机的要求。

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.
