AS 60034.7:2009 pdf – Rotating electrical machines Part 7: Classification of types ofconstruction, mounting arrangements and terminal box position (IM Code).
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.
Two 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 types 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 arrangement of machine components with regard to fixings, bearing arrangement and shaft extension
(1EV 60411.1334)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
(1EV 60411-13-35)
1.2.3
shaft extension
a portion of a shaft extending beyond an extreme bearing
(1EV 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).
