1.1 Scope This standard specifies the IM Code, a classification of types of construction, mounting arrangements and the terminal box position of rotating electrical machines. Two systems of classification are provided as follows: Code 1 (see Chapter 2): An alpha-numeric designation applicable to machines with end-shield bearing(s) and only one shaft extension. Code 2 (see Chapter 3): An all-numeric designation applicable to a wider range of types of machines including types covered by Code 1. The type of machine not covered by Code 2 should be fully described in words. The relationship between Code 1 and Code 2 is given in annex A (Informative). 1.2 Definitions For the purposes of this standard, the following definitions apply: 1.2.1 Type of construction The arrangement of machine components with regard to fixings, bearing arrangement and shaft extension (see GB/T 2900.25). 1.2.2 Mounting arrangement The orientation on site of the machine as the whole with regard to shaft alignment and position of fixings (see GB/T 2900.25). 1.2.3 Shaft extension A portion of a shaft extending beyond an extreme bearing (see GB/T 2900.25). NOTE: The bearing may be on the machine itself or be part of an assembly comprising a machine and (an) additional bearing(s). 1.2.4 Drive-end of a machine (D-end) That end of the machine which accommodates the shaft end (see GB/T 2900.25). 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: 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 extension; c) Machine with other arrangements: according to GB 1971 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 (see GB/T 2900.25).
