线性开关磁阻电机 (LSRM) 在垂直和水平推进应用中提供了线性感应电机和线性永磁电机的替代方案。本文尝试开发一种分段式二次LSRM的单元化设计方法，其特点是模块化磁路结构和多动子单元独立运行。所开发的设计方法直接在线性域中进行，无需将其转换为旋转SRM，这符合分段二次LSRM的本质，表明与传统齿型LSRM相比，它能够在相同尺寸下提供更大的功率。此外，还对关键几何参数进行了敏感性分析，并给出了选择最佳尺寸参数的指南。最后，分别使用 1 米长的定子设计并制作了三相和四相 LSRM。实验结果验证了上述设计过程和分析。
Linear switched reluctance motors (LSRMs) provide an alternative to linear induction motor and linear permanent magnet motor in both vertical and horizontal propulsion applications. This paper attempts to develop a unitized design method of a segmental secondary LSRM, which is characterized by a modular magnetic circuit structure and the independent operation of multimover units. The developed design method is directly performed in linear domain without transforming it to a rotary SRM, which complies with the essential natures of the segmental secondary LSRM, showing that it is capable of delivering more power at the same dimensions compared to the conventional tooth type LSRM. Further, the sensitivity analysis of the critical geometric parameters is performed, and the guidelines for selection of the best dimension parameters are given. Finally, the three-phase and four-phase LSRMs are designed and prototyped, respectively with a 1-m long stator. The experimental results validate the design procedures and analysis above.
