IEC 60034-4-1:2018 PDF

Scope: This part of IEC 60034 applies to three-phase synchronous machines of 1 kVA rating and larger. Most of 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 a limited applicability of the described tests@ and special precautions should be taken against irreversible demagnetization. Excluded are axial-field machines and special synchronous machines such as inductor type machines@ transversal flux machines and reluctance machines. It is not intended that this document be interpreted as requiring any or all of the tests described therein on any given machine. The particular tests to be carried out are subject to agreement between manufacturer and customer.
