arrangements and terminalbox position (IM Code).

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 lEG 60034-8 if applicable; otherwise by agreement.

NOTE The outer diameter of a forged-on flange is taken to be the diameter of the shalt extension.

1.2.5

non-drive end of the machine (N-end)

that end of the machine opposite to the drive end.
