Description
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.
