This part of IEC 60034<\/span> <\/span> is intended to establish methods of determining efficiencies from tests, and also to specify methods of obtaining specific losses.<\/p>\n

This standard applies to d.c. machines and to a.c. synchronous and induction machines of all sizes within the scope of IEC 60034\u20111<\/span> <\/span>.<\/p>\n

\n
\n NOTE\n <\/div>\n

These methods may be applied to other types of machines such as rotary converters, a.c. commutator motors and single-phase induction motors.<\/p>\n<\/div>\n
