标准摘要
[中文适用范围]： 本部分IEC 60034规定了变频器供电电机损耗和效率的测试方法及插值程序。电机作为变频驱动系统(PDS)的一部分，如IEC 61800-9-2所定义。 采用可比变频器方法，通过本文件确定的电机效率仅适用于不同低压电机设计的比较。可比变频器方法不适用于中压电机。 本文件还规定了基于七个标准化负载点损耗测定，确定恒磁通范围(恒转矩范围、基速范围)、弱磁范围和过载范围内任意负载点(转矩、转速)电机损耗的程序。该程序适用于IEC 60034-1规定的任何变频调速交流电机(感应和同步)。 [外文原描述]： 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.
