that end of the machine which accommodates the shaft end (IEV 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 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.
In Code I, a machine with a horizontal shaft is designated by the code letters IM (International Mounting), followed by a space, the letter B, one or two numerals as shown in table 1 and an optional letter as shown in 2.3.
In Code II, a machine is designated by the Code letters IM (International Mounting) followed by a space and four numerals.
The first, second and third numerals designate aspects of construction (see 3.2 and 3.4).
The fourth numeral designates the type of shaft extension (see 3.3).
When used, a letter following the four numerals shall designate the terminal box position, see 3.5.
The significance of the second and third numerals is specified in tables 5 to 13 depending on the first numeral with which they are associated (see table 3).
When designated, the terminal box position shall be coded with a final letter in accordance with the following rules:
a) machines with feet shall be viewed from the D-end with the feet at 6 o’ clock;
b) machines with flange only and with drains shall be viewed from the D-end and with the drains at 6 o’clock;
c) other configurations shall not have a coding.AS 60034.7 pdf free download.
