标准摘要
[中文适用范围]： 本IEC 63182系列标准规定了磁粉环形磁芯（也称为磁环）的尺寸，这些尺寸对于优选范围内的机械互换性至关重要；规定了计算中应使用的有效参数值；并给出了适用于 coated（涂层）环形磁芯的表面不规则性允许限度的指南。本文件芯体尺寸的选择基于包含工业标准尺寸的哲学，即这些尺寸在行业内广泛使用。本文件被视为一份分区规范，有助于磁粉磁芯制造商与用户之间就表面不规则性进行谈判。 [外文原描述]： IEC 63182-2:2020 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of ring-cores (also called toroids) made of magnetic powder, the effective parameter values to be used in calculations involving them, and gives guidelines on allowable limits of surface irregularities applicable to coated ring-cores. The selection of core sizes for this document is based on the philosophy of including those sizes which are industrial standards, meaning that they are in broad-based use within the industry. This document is considered as a sectional specification useful in the negotiations between magnetic powder core manufacturers and users about surface irregularities.
