Rotating electrical machines - Dimensions and output series - Part 1: Frame numbers 56 to 400 and flange numbers 55 to 1080
IEC 60072-1:2022 is applicable for the majority of rotating electrical machines for industrial purposes within the dimension range and output powers.- Foot- mounted: shaft heights: 56 mm to 400 mm- Flange- mounted: pitch circle diameter of flange: 55 mm to 1 080 mm.This seventh edition cancels and replaces the sixth edition published in 1991. This edition includes the following significant technical changes with respect to the previous edition:a. modification of the series title;b. complete revision on the basis of EN 50347;c. integration of the relationships between frame size, shaft extensions, rated outputs and flange numbers;d. additional tolerances and measurements for shafts;e. modification of Annex A with additional frame numbers and relationships between frame size and rated power.
