Dimensions and Output Series for Rotating Electrical Machines Part 1: Frame Numbers 56 to 400 and Flange Numbers 55 to 1080
|Publication Date:||1 February 1991|
|ICS Code (Rotating machinery):||29.160|
This part of IEC 72 covers the majority of rotating electrical machines for industrial purposes within the dimension range:
Foot- mounted : - shaft-heights: 56 mm to 400 mm
Flange- mounted: - pitch circle diameter of flange: 55 mm to 1080 mm
It gives tables of fixing dimensions, shaft extension dimensions and output powers. Maximum permissible torques for continuous duty on a.c. motors are listed for various shaft diameters.
NOTE - The dimensions for machines with shaft heights 355 mm and 400 mm, given in this standard, are included among the values given in IEC 72-2.
