API Std 546
Brushless Synchronous Machines - 500 kVA and Larger
standard by American Petroleum Institute, 06/01/1997
Full Description
Covers the minimum requirements for form-wound and bar-wound brushless synchronous machines in petroleum related industry service. The standard has been updated to include both synchronous motors and generators with two different rotor designs: (1) the conventional salient-pole rotor with solid or laminated poles, and (2) the cylindrical rotor with solid or laminated construction. Also included are new datasheet guides to help clarify the datasheet requirements.
