Rotating electrical machines - Part 2-3: Specific test methods for determining losses and efficiency of converter-fed AC motors
IEC 60034-2-3:2024 specifies test methods and an interpolation procedure for determining losses and efficiencies of converter-fed motors. The motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800?9?2. This document also specifies procedures to determine motor losses at any load point (torque, speed) within the constant flux range (constant torque range, base speed range), the field weakening range and the overload 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 for operation on a variable frequency and variable voltage power supply. This second edition cancels and replaces the first edition of IEC 60034-2-3 published in 2020. This edition includes the following significant technical changes with respect to the previous edition:- Harmonization of requirements and procedures with IEC 60034-2-1.- Extension of the interpolation procedure to the field weakening range.

Rotating electrical machines - Part 2-3: Specific test methods for determining losses and efficiency of converter-fed AC induction motors
IEC/TS 60034-2-3:2013 specifies test methods for determining losses and efficiencies of converter-fed AC induction motors within the scope of IEC 60034-1. The AC induction motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800-2, IEC 61800-4 or IEC/TS 61800-8. The additional harmonic losses determined by use of this technical specification are for comparison of different motor designs.

Rotating electrical machines - Part 2-3: Specific test methods for determining losses and efficiency of converter-fed AC motors
IEC 60034-2-3:2020 specifies test methods and an interpolation procedure for determining losses and efficiencies of converter-fed motors within the scope of IEC 60034-1:2017. The motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800?9?2:2017. 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.
