旋转电机用电气钢板和钢带技术要求

[中文适用范围]： 适用范围：IEC TS 63573-1:2026 为技术规范，规定了旋转电气电机依据 IEC 60034 系列中定子和/或转子铁芯所用材料的具体要求。本文件除适用 IEC 60404 系列标准外，面向原材料（电工钢）供应商、磁芯制造商（含可能进行的退火处理）、电机制造商以及电工钢用户。本文件不适用于电机最终用户。其旨在满足电机制造商在争取实现高 IEC 能效等级方面的迫切需求。IEC TS 63573 是一项独立的产品专用技术规范，聚焦于符合 IEC 60034 系列规定的旋转电气电机，可作为 IEC 60404-8-4 的补充。文件发布时，预期与国际电工委员会（IEC）第 68 技术委员会（磁性合金与钢材）的协作将推动对 IEC 60404-8-4:2022 的修订版第 2 版的编制。该修订版预期将厘清相关问题并提供综合性解决方案。一旦 IEC 60404-8-4:2022 的修订版第 2 版正式发布并生效，且已涵盖所识别的需求，本技术规范将予以撤消。 [外文原描述]： IEC TS 63573-1:2026, which is a Technical specification, defines specific requirements for materials to be used for the stator and/or rotor core of rotating electrical machines according to the IEC 60034 series. This document applies in addition to IEC 60404- series and is addressed to the suppliers of the raw material (electrical sheet), to producers of magnetic cores (including a possible annealing treatment), to electric motor manufacturers as well as to users of electrical steel. This document does not apply to motor customers. The objective of this document is to address the immediate needs of motor manufacturers striving to achieve high IEC efficiency classes. IEC TS 63573 is an independent product-specific specification focusing on rotating electrical machines in accordance with the IEC 60034 series and can be applied as a supplement to IEC 60404-8-4. At the time of publication of this document it is anticipated that collaboration with IEC Technical Committee 68 (Magnetic alloys and steels) will lead to the development of Amendment 2 to IEC 60404-8-4:2022. This amendment is expected to clarify the relevant issues and provide a comprehensive solution. This Technical Specification will be withdrawn once Amendment 2 to IEC 60404-8-4:2022 is published and takes effect, provided it addresses the identified need.
