摘要 永磁调速器是一种涡流式永磁磁力传动装置,根据永磁调速器的机械结构和工作原理,建立了三维电磁场有限元分析模型。通过对其进行静态磁场分析,得到静态磁场下铜盘的磁密度云图、磁密度矢量图以及磁密度周向分布图。在瞬态分析中,对涡流密度及其大小进行了分析,在忽略永磁调速器的内部漏磁和功率损耗的前提下,对多组数据下的性能参数和转矩的关系进行了有限元计算与比对。仿真结果表明:输出转矩与永磁体厚度、电导率、气隙和滑差相关,并且在性能参数既定的条件下计算输出转矩的最大值,仿真结果对永磁调速器的设计与优化有一定的指导意义。 Permanent magnet coupler is a kind of permanent magnetic transmission equipment about eddy current. According to the mechanical structure and working principle of permanent magnet coupler, the three-dimensional finite element analysis model was established. With the analysis of static magnetic field of permanent magnet coupler, magnetic density nephogram, magnetic flux density vector and magnetic density circumferential distribution map of the copper plate under the static magnetic field were got. In the transient analysis, the eddy current density and values were analyzed, and under the precondition of ignoring internal magnetic flux leakage and power loss of permanent magnet coupler, finite element calculation and comparison were made for the relationship between performance parameters of multiples sets of data and torque. The simulation results show that the output torque associated with permanent magnet thickness, conductivity, speed and air gap, and the maximum output torque was calculated in the conditions of the given parameters of performance, the simulation results for design and optimization of permanent magnet coupler has some significance.
