标准范围

IEC 60034-2-3:20 24规定了用于确定转换器馈电电机损耗和效率的测试方法和插值程序。电机是IEC 61800中定义的变频功率驱动系统（PDS）的一部分？9？2.本文件还规定了在确定七个标准化负载点的损耗的基础上，在恒定磁通范围（恒定转矩范围、基本转速范围）、弱磁范围和过载范围内确定任何负载点（转矩、转速）的电机损耗的程序。本程序适用于根据IEC 60034-1额定在可变频率和可变电压电源上运行的任何变速交流电机（感应和同步）。第二版取消并取代了2020年发布的第一版IEC 60034-2-3。与上一版相比，此版本包括以下重大技术变更:-要求和程序与IEC 60034-2-1的协调。-将插值过程扩展到弱场范围。

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.
