摘要(Abstract):

三相异步电机空载有功损耗是异步电机比较重要的性能指标之一。在三相异步电机运行效率分析的基础上,提出了三相异步电机空载有功损耗的估算方法,并分析了其在不同异步电机空载视在功率中的占比,对开展异步电机相关的工作具有一定的现实指导意义。
The no-load active power loss of three-phase asynchronous motors is among the important performance indexes for asynchronous motors.Through the analysis on its operation efficiency,this paper puts forward the estimation method for no-load active power loss of these motors.In addition,it analyzes its proportions in the no-load apparent power of different asynchronous motors and can serve as a reference for practices of the motors.
