Abstract
In this paper, the Segmental Translator Permanent Magnet Linear Switched Reluctance Motor (STPMLSRM) has been introduced as a new type of improved Linear Switched Reluctance Motor (LSRM), which increases the flux density in the air-gap by using Permanent Magnets (PMs) in the stator yoke. Also, the moving part does not have a yoke, and discrete segments are used instead of the yoke, which reduces the volume of active magnetic materials. In order to better evaluate, the segmental translator permanent magnet linear switched reluctance motor is compared with conventional linear switched reluctance motor and Segmental Translator Linear Switched Reluctance Motor (STLSRM) without permanent magnet, then their different aspects are discussed. In order to validate the introduced STPMLSRM, based on the Finite Element Method (FEM), the static and dynamic characteristics of linear motors including static flux-linkage, static force, co-energy, instantaneous current waveform, and instantaneous thrust waveform are predicted and compared. These comparisons show that the STPMLSRM has better performance characteristics than the conventional LSRM and STLSRM.
