标准摘要
[中文适用范围]： 本部分IEC 63182规定了金属磁性粉末制成的E型磁芯机械互换性的重要尺寸，与它们一起使用的线圈骨架的基本尺寸，以及计算中使用的有效参数值，并给出了适用于E型磁芯表面不规则性的允许限度的指南。 本文件是磁粉芯供应商和用户之间关于表面不规则性谈判的有用规范。 附件A讨论了使用"派生"标准的情况，这些标准提供了零件更详细的规范，同时仍允许符合本文件。 [外文原描述]： IEC 63182-3:2021 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of E-cores made of metallic magnetic powder, the essential dimensions of coil formers to be used with them as well as the effective parameter values to be used in calculations involving them, and gives guidelines on allowable limits of surface irregularities applicable to E-cores. This document is a specification useful in the negotiations between magnetic powder core suppliers and users about surface irregularities.
