标准摘要
[中文适用范围]： 本部分的 IEC 60034 规定了在 IEC 60034-1:2017 范围内的变频器供电电机的损耗和效率的测试方法及插值程序。电机随后作为 IEC 61800-9-2:2017 中定义的变频功率驱动系统 (PDS) 的一部分。应用可比较变频器的方法，使用本文件确定的电机效率仅适用于比较不同的电机设计。本文件还规定了基于在七个标准化负载点确定损耗来确定基速范围（恒转矩范围，恒磁通范围）内任何负载点（转矩、速度）的电机损耗的程序。此程序适用于按照 IEC 60034-1:2017 额定值的任何变频交流电机（感应和同步），用于在变频和变压电源上运行。 [外文原描述]： 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.
