本文研究了管式直线永磁电机，包括不同的拓扑结构，即内部安装和表面安装的永磁电机，开槽电机和无槽电机。在一些初步的分析考虑之后，重点介绍了TL-PM电机的性能，包括比力、最大加速度和成本。不仅强调了它的优点，而且还强调了它的缺点，如由于偏心而产生的阻滞力和吸引径向力。在各种分析中采用了不同的模型，必要时包括二维和三维有限元分析。此外，还报告了电机样机的预测性能与实测性能的比较。
This paper deals with tubular linear permanent magnet (TL-PM) motors, including different topologies, i.e. interior and surface-mounted PMs, slotted and slotless motors. After some preliminary analytical considerations, the performance of the TL-PM motor are highlighted, including specific force, maximum acceleration and cost. Not only the advantages are emphasised, but also the drawbacks such as detent forces and attractive radial forces due to eccentricity. Different models have been adopted in the various analyses, including 2D and 3D finite element analysis as necessary. In addition, a comparison between predicted and measured performance on a motor prototype are reported.
