摘　　要：风机、水泵机组运行效率低下,蕴藏着巨大的节能潜力,效率测量是研究风机、水泵机组节能的前提。轴功率测量是风机、水泵机组中电动机效率及风机、水泵效率测量的关键技术,本文介绍了一种无需扭矩仪的基于三相异步电动机损耗分析法的电动机轴功率测量方法,为风机、水泵机组效率测量提供了一种全新的思路。Aiming at the low operating efficiency of fan and pump units, it has tremendous potential for energy savings. Efficiency measurements is the premise of studying the energy-saving of fan and pump units, while shaft power measurement is the key technique for measuring motor efficiency, fan and pump efficiency in the fan and pump units. This paper introduces a motor shaft power measurement method based on three-phase asynchronous motor loss analysis and without torque meter, which has provided a tolly new route for measuring fan and pump units efficiency.
