摘　　要：利用Ansoft Maxwell软件对矿用永磁耦合器建模仿真,得出气隙越小转矩越大且转矩随转差率的变化类似于异步电动机机械特性的结论,分析了通过调节气隙大小,实现调速控制的可行性。提出永磁耦合器调速机构的整体设计方案,并对目前煤矿生产中常用的几种调速控制技术进行了分析对比,揭示永磁传动调速更适合井下恶劣环境的特点。最后探讨在泵类负载上采用永磁耦合器控制转速,可产生显著的节能效果和经济效益。For permanent magnet coupler,the modeling and simulation is finished with Ansoft Maxwell. It is concluded that the air- gap is smaller and the torque is greater. The simulation shows that the rule of torque is similar to the mechanical properties of asynchronous motor along with the change of slip. Under the load,the feasibility of speed control is analyzed with air-gap size adjustment. Moreover,the overall design scheme is proposed for permanent magnet coupler＇s speed control institutions. Several speed control technologies commonly used in coal mine production are compared,showing that the permanent magnet drive technology is more suitable for underground environment. Finally the energy saving effect and economic benefits is discussed,using permanent magnet coupler for speed control of pump load.
