针对直线永磁游标电机的损耗问题,提出一种磁障式拓扑结构.通过在次级的凸极齿加入隔磁磁障,使次级对磁通的流动具有导向作用,减少涡流损耗,提高电机的磁场调制能力.在此基础上,设计一种磁障式直线永磁游标电机,采用响应面(RSM)-正交法对电机的推力性能进行优化.首先,通过对电机进行灵敏度分析,确定显著变量.其次,根据RSM法建立优化目标响应与显著变量之间的拟合模型,并对其拟合精度进行评估.最后,基于该模型进行正交试验,根据正交试验的数据进行极差分析,得到电机的最优结构参数.有限元实验结果表明,采用RSM-正交优化方法的电机性能得到大幅提高,并且可以节省优化时间,提高优化效率,对直线永磁游标电机的设计与优化有重要的参考价值.
Design and optimization of magnetic barrier linear permanent magnet vernier motor based on RSM orthogonal method
A magnetic barrier topology structure was proposed to address the loss issue of linear permanent magnet vernier motors.By adding magnetic barriers to the secondary salient teeth,the secondary has a guiding effect on the flow of magnetic flux,reduces eddy current losses,and improves the magnetic field modulation ability of the motor.On this basis,a magnetic barrier linear permanent magnet vernier motor was designed,and the thrust performance of the motor was optimized using the response surface methodol-ogy(RSM)orthogonal method.Firstly,by conducting sensitivity analysis on the motor,significant varia-bles were determined.Secondly,a fitting model was established between the optimization target response and significant variables using the RSM method,and its fitting accuracy was evaluated.Finally,based on the model,orthogonal experiments were conducted,and range analysis was performed on the data from the orthogonal experiments to obtain the optimal structural parameters of the motor.The finite element ex-perimental results show that the motor performance is significantly improved by using the RSM orthogonal optimization method,which can save optimization time and improve optimization efficiency.The above work has important reference value for the design and optimization of linear permanent magnet vernier motors.
