对直线初级永磁游标电机(LPPMV)和直线游标混合电机(LVH)进行了比较。LPPMV电机和LVH电机均基于磁齿轮原理运行，具有低速、高推力密度的优点。此外，两台机器采用相似的配置，其关键区别在于LPPMV机器采用的是整体式原生铁芯，而不是LVH机器的模块化铁芯。利用有限元方法对两种机床的特点和性能进行了分析和比较。结果表明，LPPMV电机具有较大的推力和较小的齿槽力。最后，以LPPMV样机为例，对有限元计算结果进行了验证。
This paper presents the comparison of linear primary permanent magnet vernier (LPPMV) machine and linear vernier hybrid (LVH) machine. The LPPMV machine and the LVH machine both operate based on the magnetic gear principle, hence possessing the advantages of low speed and high thrust force density. In addition, both machines employ similar configurations between which the key difference is that a one-piece primary iron core is employed in the LPPMV machine instead of the modular cores in the LVH machine. Using the finite element method (FEM), the characteristics and performances of two machines are analyzed and compared. The results show that the LPPMV machine exhibits higher thrust force and lower cogging force. Finally, the FEM results are validated by experiments based on a prototype of the LPPMV machine.
