Scope

<!-- NEW! -->IEC 60034-2-1:2024 is available as <a href="https://webstore.iec.ch/publication/93054">IEC 60034-2-1:2024 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.</br></br>IEC 60034-2-1:2024 is intended to establish methods of determining efficiencies from tests, and also to specify methods of obtaining specific losses. This document applies to DC machines and to AC synchronous and induction machines of all sizes within the scope of IEC 60034-1 rated for mains operation. These methods may be applied to other types of machines such as rotary converters, AC commutator motors and single-phase induction motors. This third edition cancels and replaces the second edition of IEC 60034-2-1 published in 2014. This edition includes the following significant technical changes with respect to the previous edition:

- Harmonization of layout and requirements with IEC 60034-2-2 and IEC 60034-2-3.
