摘　　要：设计了一种混合励磁开关磁通永磁记忆电机,利用Ansoft Maxwell 2D仿真软件建立了其电机模型,分析了其电机运行原理。采用有限元分析方法,对电机的调磁特性进行了探究,给出了铝镍钴永磁体处于不同磁化状态时的磁力线分布、相磁链曲线、反电动势曲线、磁通密度分布曲线和转矩波形曲线。仿真结果表明,该电机相较于常规永磁同步电机具有良好的调磁性能。A switched flux hybrid magnet memory motor was designed. The simulation model was established in Ansoft Maxwell 2D software. The operation principle of the motor was analyzed. The flux adjusting of the motor was researched by using the finite element analysis method. The motor＇s flux_lines, fluxlinkage of winding A, reverse electromotive force curves, magnetic flux density curves and torque waveform curves under different magnetizing state of AlNiCo PMs were given. The simulation results showed that compared with the traditional permanent magnet synchronous moto, the motor had good flux adjusting ability.
