This part of IEC 60034 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.
NOTE These methods may be applied to other types of machines such as rotary converters, AC commutator motors and single-phase induction motors.
