摘要: A multi-tooth switched-flux linear motor (MTSFLM), with a novel armature structure, is proposed. In its the height of permanent magnets (PMs) not same as that iron cores, which different conventional (SFM). Firstly, MTSFLM tooth-slot parameters corresponding rotatory showed, pointing out coil areas much smaller than form. The 2.5 times high discussed then to enlarger slot areas. Secondly, it pointed higher may lead serious saturation if core and PMs are still kept design. shorter PMs, in And optimization investigated produce optimum output characteristics. Thirdly, unique impacts yoke gap distance on value discussed. Finally, prototype optimized structure presented. measured back-EMF, detent force data compared those from FEM, result curves validated aforesaid analyses.
