摘要
为了研究一种定子采用类爪极磁极铁心形状及环形集中绕组的三维磁路结构的磁通切换型永磁电机,在对空载静磁场及电枢反应磁场进行三维有限元磁场计算的基础上,根据电机在不同定、转子相对位置时的磁场分布情况,对三维磁路结构进行集中参数磁路模型建模,并推导出节点磁动势矩阵,通过对矩阵进行解析计算以及对计算结果的分析,推导出电机各主要电磁参数的解析表达式并进行计算和分析,通过与三维磁场计算结果相对比,验证了该磁路模型计算方法的正确性。由于可采用集中参数磁路模型计算可以节省大量计算时间,可以更方便地进行三维磁路结构电机的各种参数优化,对其他三维磁路和分析工作也具有参考意义。
In order to study one flux switching permanent-magnet machine with a quasi-claw-pole stator core structure and a circular concentrate winding pattern, 3-dimentional electromagnetic field calculations were carried to analyze no-load static magnetic fields and armature reaction magnetic fields respectively. Then one 3-dimentional lumped-parameter magnetic circuit model was built based on the analysis of the magnetic field distributions at different rotor positions in the machine. Firstly the node magneto motive force matrix were derived and solved, then the analytical expressions of main electromagnetic parameters were concluded and analyzed. The correctness of the lumped parameter magnetic circuit calculation model was verified by comparing the results calculated with the corresponding 3-dimentional finite element anal-ysis results. The lumped parameter magnetic circuit model calculations take much less time than conduc-ting 3-dimentional finite element analysis, so optimizations of various parameters of the machine with three-dimensional magnetic structure can be carried out less costly, and can be a reference to analysis of other machines with 3-dimentional flux paths.
