标准摘要
[中文适用范围]： 本技术规范适用于符合 IEC 60349-2 的电机。转换器供电电机的总损耗可以通过对空载和负载试验得出的组件损耗进行求和来确定。总输入功率是基波频率功率和所有其他频率功率的总和。在所有实际情况下，后者包括由转换器供电引起的电压和电流谐波损耗，通过使用合适的仪器，当机器在负载下时，可以通过测量总输入功率和基波频率输入功率来推导。基波频率提供的损耗无法直接测量，因此通过测量基波频率负载电流和基波频率空载输入功率来推导。 [外文原描述]： IEC/TS 60349-3:2010 applies to machines complying with IEC 60349-2. The losses supplied at the fundamental frequency cannot be measured directly and so are derived from measurement of the fundamental frequency load current and the fundamental frequency no-load power input. The main technical changes with regard to the previous edition are corrections in some formulas in 3.2.1.2 and in Table A.2.
