IEC 60034-2-3 Revised
Applying the approach of the comparable converter, the motor efficiency determined by use of this document is applicable for comparison of different motor designs only.
The document also specifies procedures to determine motor losses at any load point (torque, speed) within the base speed range (constant torque range, constant flux range) based on determination of losses at seven standardized load points. This procedure is applicable to any variable speed AC motor (induction and synchronous) rated according to IEC 60034-1:2017 for operation on a variable frequency and variable voltage power supply.
