28、 types of construction, mounting arrangements and terminal box position (IM Code) Section 1: Scope and definitions 1.1 Scope This part of IEC 60034 specifies the IM Code, a classification of types of construction, mounting arrangements and the terminal box position of rotating electrical machines. T
29、wo systems of classification are provided as follows: Code I (see section 2): An alpha-numeric designation applicable to machines with end- shield bearing(s) and only one shaft extension. Code II (see section 3): An all-numeric designation applicable to a wider range of types of machines including t
30、ypes covered by Code I. The type of machine not covered by Code II should 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 60034, the following definitions apply: 1.2.1 type of construction the arrangem
31、ent of machine components with regard to fixings, bearing arrangement and shaft extension (IEV 60411-13-34)1) 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 60411-13-35) 1.2.3 shaft extension a portion of a s
32、haft extending beyond an extreme bearing (IEV 60411-13-07) NOTE The bearing may be on the machine itself or be part of an assembly comprising a machine and (an) additional bearing(s). 1) IEC 60050(411): 1973, International Electrotechnical Vocabulary (IEV) Chapter 411: Rotating machinery.

Where for some machines the above definition is inadequate, the D-end is
34、 defined as follows: 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 with cylindrical shaft extention; c) Machine with other arrangements: acc
35、ording to IEC 60034-8 if applicable; otherwise by agreement. NOTE The outer diameter of a forged-on flange is taken to be the diameter of the shaft extension. 1.2.5 non-drive end of the machine (N-end) that end of the machine opposite to the drive end (IEV 60411-13-37).
