1 Scope This part applies to DC machines and to AC synchronous and induction machines of all sizes within the scope of national standard GB 755-2000. The principles can, however, be applied to other types of machines such as rotary convertors, AC commutator motors and single-phase induction motors for which other methods of determining losses are generally used. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this part. For dated references, subsequent amendments to (excluding amending errors in the text), or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this part are encouraged to study whether the latest edition of the normative document is applicable. For undated references, the latest edition of the normative document applies.
