What is BS EN IEC 60034-4-1 - Rotating electrical machines about?
The IEC 60034 is a European Standard series that covers rotating electrical machines and their requirements.
BS EN IEC 60034-4-1 is one of the parts of the IEC 60034 series that specifies the methods are intended to be used for machines having an excitation winding with slip-rings and brushes for their supply. Synchronous machines with brushless excitation require special effort for some of the tests. For machines with permanent magnet excitation, there is limited applicability of the described tests, and special precautions should ...
