| 摘 要： | 针对数值法或解析法研究永磁直线同步电机(permanent magnet linear synchronous motor,PMLSM)性能时存在的不足,采用数值解析混合法研究PMLSM磁场,把电机的磁场划分区域,针对各区域特点分别采用纯解析法和数值法,气隙区包括永磁体无网格剖分,采用解析法获得此区的磁场解析表达式;初级齿槽区采用有限元法研究电枢不同励磁形式、齿槽及端部半填槽对磁场的影响.解析和有限元法通过两者的边界条件相耦合,建立并求解电机的磁场,获得空载电势与磁链参数,分析工作在SPWM-VI下PMLSM的动态性能,提出PMLSM空载电势实验的一种新方法,仿真和实验结果进行比较分析,验证了数值解析混合法分析PMLSM性能的正确性及快速性.
