Dimensions and output series for rotating electrical machines - Part 2: Frame numbers 355 to 1000 and flange numbers 1180 to 2360 (IEC 60072-2:2025)
IEC 60072-2: 2025 covers the majority of rotating electrical machines for industrial purposes within the dimension range and output powers:
- Foot-mounted: shaft heights: 355 mm to 1 000 mm.
- Flange-mounted: pitch circle diameter of flange: 1 180 mm to 2 360 mm.
It gives tables of fixing dimensions, shaft extension dimensions and their tolerances. However, the variety of construction and the wide range of applications for the large machines with shaft heights above 315 mm have led to the establishment of a relatively large number of values for the dimension in order to cover all possible constructions. Owing to this, the present part covers a wider range than IEC 60072-1 within which range values suitable for all designs or for a more detailed standardization can be chosen. NOTE The mounting dimensions given in this document for shaft heights 355 mm and 400 mm have been chosen from values given in IEC 60072-1.
This second edition cancels and replaces the first edition published in 1990. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) complete revision on the basis of IEC 60072-1;
b) additional tolerances and measurements for shafts and flanges (DIN SPEC 42955).
Maße und Leistungsreihen für drehende elektrische Maschinen - Teil 2: Baugrößen 355 bis 1000 und Flanschgrößen 1180 bis 2360 (IEC 60072-2:2025)
Dimensions et séries de puissances des machines électriques tournantes - Partie 2: Désignation des carcasses entre 355 et 1000 et des brides entre 1180 et 2360 (IEC 60072-2:2025)
IEC 60072-2:2025 couvre la majorité des machines électriques tournantes pour usages industriels dans la gamme des dimensions et les puissances:
- Fixation par pattes: hauteurs d'axes: 355 mm à 1 000 mm.
- Fixation par bride: diamètre du cercle primitif de la bride: 1 180 mm à 2 360 mm.
Elle donne les tableaux des dimensions de fixation, des dimensions des bouts d'arbre et de leurs tolérances. Toutefois, la diversité des conceptions et la vaste gamme d'applications des grandes machines présentant des hauteurs d'axes supérieures à 315 mm ont conduit à l'établissement d'un nombre relativement important de valeurs de dimensions afin de couvrir toutes les conceptions possibles. De ce fait, la présente partie couvre une gamme de dimensions plus large que l'IEC 60072-1, parmi lesquelles des valeurs appropriées peuvent être choisies pour toutes les conceptions ou pour effectuer une normalisation plus détaillée. NOTE Les dimensions de fixation indiquées dans le présent document pour des hauteurs d'axes de 355 mm et 400 mm ont été choisies à partir des valeurs fournies dans l'IEC 60072-1.
Cette deuxième édition annule et remplace la première édition parue en 1990. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) révision complète par rapport à l'IEC 60072-1;
b) ajout de tolérances et de mesurages pour les arbres et les brides (DIN SPEC 42955).

47 FOREWORD
48 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
49 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
50 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
51 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
52 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
53 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
54 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
55 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
56 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
57 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
58 consensus of opinion on the relevant subjects since each technical committee has representation from all
59 interested IEC National Committees.
60 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
61 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
62 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
63 misinterpretation by any end user.
64 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
65 transparently to the maximum extent possible in their national and regional publications. Any divergence between
66 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
67 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
68 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
69 services carried out by independent certification bodies.
70 6) All users should ensure that they have the latest edition of this publication.
71 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
72 members of its technical committees and IEC National Committees for any personal injury, property damage or
73 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
74 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
75 Publications.
76 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
77 indispensable for the correct application of this publication.
78 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
79 rights. IEC shall not be held responsible for identifying any or all such patent rights.
80 International Standard IEC 60072-1 has been prepared by subcommittee WG12: Rating,
81 performance and general support, of IEC technical committee TC2: Rotating machinery.

1 DIMENSIONS AND OUTPUT SERIES
2 FOR ROTATING ELECTRICAL MACHINES –
4 Part 2: Frame numbers 355 to 1000 and flange numbers 1180 to 2360
6 1 Scope
7 This part of IEC 60072-2 covers the majority of rotating electrical machines for industrial
8 purposes within the dimension range and output powers:
9 Foot-mounted: shaft heights: 355 mm to 1000 mm
10 Flange-mounted: pitch circle diameter of flange: 1180 mm to 2360 mm
11 It gives tables of fixing dimension, shaft extension dimensions and their tolerances. However,
12 the variety of construction and the wide range of applications for the large machines with shaft
13 heights above 315 mm have led to the establishment of a relatively large number of values for
14 the dimension in order to cover all possible constructions. Owing to this, the present part covers
15 a wider range than IEC 60072-1 within which, range values suitable for all designs or for a more
16 detailed standardization can be chosen.
18 Note: the mounting dimensions given in this part for shaft heights 355 mm and 400 mm have been chosen from
19 values given in IEC60072-1
