Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 12: Ring-cores

This part of IEC 63093 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of ring-cores, also called toroid cores, and the effective parameter values to be used in calculations involving them. It also gives guidelines on allowable limits of surface irregularities applicable to ring-cores. This document is a specification useful in the negotiations between ferrite core manufacturers and users about surface irregularities.

Noyaux ferrites - Lignes directrices relatives aux dimensions et aux limites des irrégularités de surface - Partie 12: Noyaux toriques

La présente partie de l’IEC 63093 spécifie les dimensions importantes pour l’interchangeabilité matérielle d’une gamme préférentielle de noyaux toriques, et les valeurs des paramètres effectifs à utiliser dans les calculs les impliquant. Elle donne également des lignes directrices relatives aux limites admises des irrégularités de surface applicables aux noyaux toriques. Le présent document est une spécification utile dans les négociations entre les fabricants et les clients de noyaux ferrites au sujet des irrégularités de surface.

Feritna jedra - Smernice o merah in mejnih vrednostih površinskih nepravilnosti - 12. del: Obročasta jedra

Ta del standarda IEC 63093 določa mere, ki so pomembne za mehansko medsebojno zamenljivost prednostnega razpona obročastih jeder, imenovanih tudi toroidna jedra, in dejanske vrednosti parametrov, ki se uporabljajo pri izračunih, povezanih s temi jedri. Podaja tudi smernice glede omejitev površinskih nepravilnosti, ki veljajo za obročasta jedra.
Ta dokument je specifikacija, uporabna za sklepanje dogovorov o površinskih nepravilnostih med proizvajalci in uporabniki feritnih jeder.
