| 摘 要： | 设计了一种基于异步电机笼型转子的调速型异步磁力耦合器(SRAMC),推导出其转矩与转差率关系式,并据此分析了SRAMC起动特性、拐点特性及同步特性的运行机理。建立了SRAMC有限元仿真模型,得到了转矩与转速曲线、转矩与转差率关系及相应的调速特性曲线。通过分析所建模型及上述曲线,得到了SRAMC起动及额定转矩与气隙磁密、永磁体极距及其耦合长度的平方成正比,且其最大转矩与内转子笼条电阻无关等结论。另外,SRAMC具有较为优异的调速特性,将其应用于离心式负载时,可获得较好的节能收益。

| Abstract: | A kind of speed regulating asynchronous magnetic coupler(SRAMC) based on cage rotor of asynchronous motor is designed. The relationship between torque and slip ratio is deduced. Based on this, the operation mechanisms of SRAMC′s starting characteristics, inflection point characteristics and synchronization characteristics are analyzed. The SRAMC finite element simulation model is established. The torque and speed curves, the relation between torque and slip ratio, and the corresponding speed regulation characteristic curves are obtained. Through the analysis of the established model and the above-mentioned curves, it is concluded that the starting and rated torques of SRAMC are proportional to the air gap magnetic density, the polar distance of permanent magnet and the square of coupling length, and its maximum torque is independent of the resistance of inner rotor cage strip. In addition, SRAMC has excellent speed regulation characteristics, and good energy saving benefits can be obtained when it is applied to centrifugal load. |
