Introduction This part of IEC 617 forms an element of a series which deals with graphical symbols for diagrams. The series consists of the following parts: — Part 1: General information, general index. Cross-reference tables; — Part 2: Symbol elements, qualifying symbols and other symbols having general application; — Part 3: Conductors and connecting devices; — Part 4: Basic passive components; — Part 5: Semiconductors and electron tubes; — Part 6: Production and conversion of electrical energy; — Part 7: Switchgear, controlgear and protective devices; — Part 8: Measuring instruments, lamps and signalling devices; — Part 9: Telecommunications: Switching and peripheral equipment; — Part 10: Telecommunications: Transmission; — Part 11: Architectural and topographical installation plans and diagrams; — Part 12: Binary logic elements; — Part 13: Analogue elements. The scope and the normative references for this series are given in IEC 617-1. Symbols have been designed in accordance with requirements given in the future ISO 11714-11). The module size M = 2,5 mm has been used. For better readability smaller symbols in this standard have been enlarged to double size and are marked “200 %” in the symbol column. To save space larger symbols have been reduced to half size and are marked “50 %” in the symbol column. In accordance with the future ISO 11714-1, clause 7, symbol dimensions (for instance height) may be modified in order to make space for a greater number of terminals or for other layout requirements. In all cases, whether the size is enlarged or reduced, or dimensions modified, the thickness of the original line should be maintained without scaling.
1)
The symbols in this standard are laid out in such a way that the distance between connecting lines is a multiple of a certain modulus. Modulus 2M has been chosen to provide enough space for the required terminal designation. The symbols have been drawn to a size convenient for comprehension, using consistently the same grid in the representation of all symbols. All symbols are designed within a grid in a computer-aided draughting system. The grid which was used has been reproduced in the background of the symbols. The older symbols which were included in appendix A of the first edition of IEC 617-6 for a transitional period, are no longer part of this second edition, as they will definitely be withdrawn from use. The indexes in Annex B and C include an alphabetic list of symbol names and their corresponding number. The symbol names are based on the description of the symbols of this part. A general index including an alphabetic list of symbols of all parts is given in IEC 617-1.
At present, at the stage of Draft International Standard (document 3/563/DIS).

II convient que le symbole général pour une machine (06-04-01) soit utilisé pour représenter une machine asynchrone dont le rotor n’a pas de connexions extérieures, par exemple pour un moteur à rotor en court-circuit.

Symbol
The general symbol for a machine (06-04-01) should be used to represent an asynchronous machine, if no external connections to the rotor exist, for example in a squirrel cage motor. An inner circle, representing the rotor, should be shown in those cases where external connections to the rotor exist, see for example symbol 06-08-03.

Deux formes de symboles sont données pour un même type de transformateur:
Chapter III: Transformers and reactors 1
Two forms of symbols are shown for the same type of transformer:
— En forme 1: Chaque enroulement est représenté par un cercle. Cette utilisation est de préférence limitée à la représentation unifilaire. Les symboles des noyaux de transformateurs ne sont pas utilisés dans cette forme.
— Form 1 uses a circle to represent each winding. Its use is preferably restricted to single-line representation. Symbols for transformer cores are not used with this form.
— En forme 2: Chaque enroulement est représenté par le symbole 04-03-01. On peut différencier entre certains enroulements par le nombre de demi-cercles.
— Form 2 uses symbol 04-03-01 to represent each winding. The number of half-circles may be varied to differentiate between certain windings.

La note 2 du symboles 04-03-01 est applicable à la représentation du noyau d’un transformateur.

For the representation of transformer cores, see Note 2 with symbol 04-03-01.

Dans les symboles de transformateurs de courant ou d’impulsion, des traits droits peuvent être utilisés pour représenter des enroulements primaires. Voir section 13.
