AS 60034.7:2009 pdf free download – Rotating electrical machines Part 7: Classification of types ofconstruction, mounting arrangements and terminal box position (IM Code).
The type of machine not covered by Code II should be fully described in words. The relationship between Code I and Code Il 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 60411.13.34)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
(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 bearln9 flay be on the machine itself pr be part of an assembly comprisiny a macnine ano fl) additional bearing(s).
1.2.4
drive-end of a machine (D-end)
that end of the machine which accommodates the shaft end
(1EV 60411-13-36)
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:
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: according to EC 60034-8 if applicable: otherwise by agreement.
NOTE The outer diameter of a forged-on (lange 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.
