Omfang

urn:iec:std:iec:60072::::This part of IEC 60072 covers the majority of rotating electrical machines for industrial purposes within the dimension range and output powers:Foot-mounted: shaft heights: 355 mm to 1 000 mm.Flange-mounted: pitch circle diameter of flange: 1 180 mm to 2 360 mm.It gives tables of fixing dimensions, shaft extension dimensions and their tolerances. However, the variety of construction and the wide range of applications for the large machines with shaft heights above 315 mm have led to the establishment of a relatively large number of values for the dimension in order to cover all possible constructions. Owing to this, the present part covers a wider range than urn:iec:std:iec:60072-1::::IEC 60072-1 within which range values suitable for all designs or for a more detailed standardization can be chosen.The mounting dimensions given in this document for shaft heights 355 mm and 400 mm have been chosen from values given in urn:iec:std:iec:60072-1::::IEC 60072-1.
