It was derived by CENELEC from IEC 60034-7: 1992 including amendment 1:2000 published by

9、 the International Electrotechnical Commission (IEC). This British Standard supersedes BS 4999-107:1987 which is withdrawn. The start and finish of text introduced or altered by amendment is indicated in the text by tags B a. Tags indicating changes to IEC text carry the number of the IEC amendment.

10、 For example, text altered by IEC amendment 1 is indicated byB a. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered to IEC 60027-1. For a period of time during the change over from one numbering system to the other, pu

30、rmation Handling ServicesEN 60034-7:1993 Section 1. Scope and definitions 1.1 Scope This part of IEC 34 specifies the IM code, a classification of types of construction and mounting arrangements of rotating electrical machines. Two systems of classification are provided as follows: - Code I (see sec

31、tion 2): - Code II (see section 3): An alpha-numeric designation applicable to machines with endshield bearing(s) and only one shaft extension. An all-numeric designation applicable to a wider range of types of machines including types covered by Code I. The type of machine not covered by Code II sh

32、ould be fully described in words. The relationship between Code I and Code II is given in Annex A. 1.2 Definitions For the purposes of this part of IEC 34, the following definitions apply: 1.2.1 type of construction the arrangement of machine components with regard to fixings, bearing arrangement an

33、d shaft extension (IEV 4 11- 13-34)l) 1.2.2 mounting arrangement the orientation on site of the machine as the whole with regard to shaft alignment and position of fixings (IEV 411-13-35) 1.2.3 shaft extension a portion of a shaft extending beyond an extreme bearing (IEV 411-13-07) NOTE 1.2.4 drive-

34、end of a machine (D-end) that end of the machine which accommodates the shaft end (IEV 411-13-36) NOTE This is normally the driving end of a motor or the driven end of a generator. Where for some machines the above definition is inadequate, the D-end is defined as follows: The bearing may be on the

35、machine itself or be part of an assembly comprising a machine and (an) additional bearing(s). a) machine with two shaft extensions of different diameter: the end with the larger shaft diameter; b) machine with a cylindrical shaft extension and a conical shaft extension of the same diameter: the end

36、with cylindrical shaft extension; c) machine with other arrangements: according to IEC 34-8 if applicable; otherwise by agreement. NOTE 1.2.5 non-drive end of the machine (N-end) that end of the machine opposite to the drive end (IEV 411-13-37) The outer diameter of a forged-on flange is taken to be

37、 the diameter of the shaft extension. 1) IEC 50 (411):1973, International Electrotecbnical Vocabulary (IEV), Chapter 411: Rotating machines.
