标准范围

IEC 60034-2-3:20 20规定了在IEC 60034-1:20 17范围内确定转换器馈电电机的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？2:2017.应用可比转换器的方法，通过使用本文件确定的电机效率仅适用于不同电机设计的比较。该文件还规定了基于确定七个标准化负载点的损耗来确定基本速度范围（恒定转矩范围、恒定磁通范围）内任何负载点（转矩、速度）的电机损耗的程序。本程序适用于根据IEC 60034-1:20 17额定在变频和可变电压电源上运行的任何变速交流电机（感应和同步）。

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.
