提出了一种新型的双面无叉多齿线性开关磁通永磁（DYMLSFPM）电机，从力脉动和齿槽力两方面改善了传统双面线性开关磁通永磁（DLSFPM）电机的电磁性能。其结构特点是无轭的多齿初级齿。首先，提出了一种确定主槽和次极最佳组合的导磁模型解析方法。对于具有六个主槽的DYMLSFPM电机，分别有四个不同的二次极16/17/19/20。通过对比四种组合的结果，表明具有19副极的DYMLSFPM电机具有更好的推力性能，并通过有限元分析验证了这一点。4种结构先进行单变量优化，再进行遗传算法全局优化进一步分析，6槽/19杆（6s/19p）组合的平均推力第二高，推力脉动最低。此外，与传统的6s/7p DLSFPM电机相比，它需要更小的pm体积和更低的齿槽力。最后，制作了一个6s/19p DYMLSFPM电机样机并进行了测试，验证了预测结果。
A novel double-sided yokeless multitooth linear switched-flux permanent magnet (DYMLSFPM) motor is proposed to improve the electromagnetic performance of conventional double-sided linear switched-flux PM (DLSFPM) motor in terms of force ripple and cogging force. Its feature of structure is the multitooth primary without yoke. First, an analytical method of permeance model is developed for determining the optimal combination of primary slots and secondary poles. For DYMLSFPM motor with six primary slots, there are four available different secondary poles 16/17/19/20, respectively. By comparing the results of four combinations, it shows that the DYMLSFPM motor with 19 secondary poles can have better thrust force performance, which is also verified by the finite-element analysis. After all these four structures are optimized first by single-variable optimization and then by global optimization with genetic algorithm for further analysis, 6-slots/19-poles (6s/19p) combination can have the second highest average thrust force and the lowest thrust ripple. Moreover, it requires significantly smaller volume of PMs and exhibits much lower cogging force than conventional 6s/7p DLSFPM motor. Finally, a prototype of 6s/19p DYMLSFPM motor is manufactured and tested to validate the predicted results.
