(Main)Magnetic powder cores - Guidelines on dimensions and the limits of surface irregularities - Part 3: E-cores
Magnetic powder cores - Guidelines on dimensions and the limits of surface irregularities - Part 3: E-cores
This part of IEC 63182 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.
The use of "derived" standards which give more detailed specifications of component parts
while still permitting compliance with this document is discussed in Annex A.
Magnetische Pulverkerne – Leitlinien zu Maßen und Grenzen von Oberflächenbeschädigungen - Teil 3: E-Kerne
Noyaux en poudre magnétique – Lignes directrices concernant les dimensions et les limites des irrégularités de surface – Partie 3: Noyaux E
L’IEC 63182-3:2021 spécifie les dimensions qui sont importantes pour l’interchangeabilité mécanique d’une gamme préférentielle de noyaux E en poudre magnétique métallique, ainsi que les dimensions essentielles des supports de bobinages à employer avec ces noyaux E. Elle spécifie également les valeurs des paramètres effectifs à utiliser dans les calculs concernant ces derniers et donne des lignes directrices relatives aux limites admissibles des irrégularités de surface applicables aux noyaux E.
Le présent document est une spécification utile pour les négociations sur les irrégularités de surface entre les fournisseurs et les utilisateurs de noyaux en poudre magnétique.
Jedra iz magnetnega prahu - Smernice o merah in mejnih vrednostih površinskih nepravilnosti - 3. del: E-jedra
Ta del standarda IEC 63182 določa mere, ki so pomembne za mehansko medsebojno zamenljivost prednostnega razpona E-jeder, izdelanih iz kovinskega magnetnega prahu, bistvene mere tuljave, ki se uporablja s temi jedri, in vrednosti efektivnih parametrov, ki se uporabljajo pri izračunih, povezanih z jedri, ter podaja smernice o dovoljenih mejnih vrednostih površinskih nepravilnosti, ki se uporabljajo za E-jedra. Ta dokument je specifikacija, uporabna za sklepanje dogovorov o površinskih nepravilnostih med dobavitelji in uporabniki jeder iz magnetnega prahu. Uporaba »izpeljanih« standardov, ki podajajo podrobnejše specifikacije o delih komponent in hkrati dovoljujejo skladnost s tem dokumentom, je obravnavana v dodatku A.

MAGNETIC POWDER CORES – GUIDELINES ON DIMENSIONS

Part 3: E-cores
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 63182-3 has been prepared by IEC technical committee 51: Magnetic components, ferrite
and magnetic powder materials. It is an International Standard.
The text of this International Standard is based on the following documents:
