本文评估了管状永磁（PM）电机的每极分数槽绕组配置的性能，该配置可以以简单且具有成本效益的方式有效地消除最不希望的空间谐波。建议的机器拓扑绕组配置的好处说明通过比较与9槽，10极管状PM机开发的自由活塞能量转换器在相同的规格和体积约束。它已被证明，拟议的机器拓扑结构的结果在动子磁体和支撑管中的涡流损耗减少超过7倍，因此避免了潜在的问题，过高的动子温度和退磁的风险。
This paper evaluates the perforamnce of fractional-slot per pole winding con- figurations for tubular permanent magnet (PM) machines that can effectively eliminate the most undesirable space harmonics in a simple and cost-effective manner. The benefits of the proposed machine topology winding configurations are illustrated through comparison with 9-slot, 10-pole tubular PM machine developed for a free piston energy converter under the same specification and volumetric constraints. It has been shown that the pro - posed machine topology results in more than 7 times reduction in the eddy current loss in the mover magnets and supporting tube, and hence avoids potential problem of excessive mover temperature and risk of demagnetization.
