“…Figure 1 shows the structures diagram of two 6s/19p DMTFSLMs, which are both moving primary format (Lu et al, 2015). Figure 1(a) shows DMTFSLM with yoke which is obtained by combining the primaries of two same single-side MTFSLMs back-to-back, called normal DMTFSLM.…”

AbstractPurpose -Due to the advantages of direct driven, high thrust density, and high efficiency, flux-switching linear motor (FSLM) is required for many applications, including aerospace and automotive. However, the vibration caused by detent force and difficulties in the assembly produced by the large normal force become the barriers that restrict its development. The paper aims to discuss these issues. Design/methodology/approach -In order to improve the electromagnetic performance of double-sided multi-tooth FSLM (DMTFSLM), a yokeless DMTFSLM with moving primary is proposed and compared with normal DMTFSLM. Moreover, with theoretical analysis, the selection principle of slot-pole number combination is obtained. DMTFSLMs with four slot/pole combinations, 6s/16p, 6s/17p, 6s/19p, 6s/20p, are analyzed based on finite element analysis model. Finally, several parameters of this yokeless DMTFSLM have been optimized to obtain the better performance. Findings -In yokeless DMTFSLM, it is found that the asymmetry of Back-EMF caused by the end-effect is eliminated, which leads to a better thrust force performance in comparison with the normal structure. The small attractive force between the secondary and the primary makes it easier for assembly and also can reduce the friction, which is more suitable for high-speed application. In addition, the best slot-pole combination rul...

“…Literature about comparison of dual stator and dual mover topologies is very scarce [17,18], authors of [17] investigated both topologies of double-sided LPMFSM with multi-tooth configuration and yokeless primary. However, mechanical integrity of LPMFSM with yokeless primary is compromised as epoxy risen is used to encapsulate and hold mover modules together [19].…”

Short moving primary and rigid low-cost secondary are important requirements of linear machines designed for long stroke applications. In the race, linear permanent magnet flux switching machine (LPMFSM) is a competitive candidate by confining excitation sources to short mover, thus making stator robust and low cost (made of only iron). However, single-sided LPMFSM exhibit a demerit of high normal (attraction) force due to its topology. In order to rectify the problem and enhance thrust force profile, two novel double-sided LPMFSMs are proposed with dual stator and dual mover topologies. After stator pole study, both topologies with same design dimensions are analysed and compared by 2-D finite element method here. Detailed analysis revealed that 12/14 DMLPMFSM exhibit low numerical values of thrust force ripples and detent force while maintaining average thrust force value. Hence, 12/14 DMLPMFSM is selected and optimised by structure-based deterministic optimisation (SBDO) approach to further enhance thrust force profile. Finally, comparison of initial and optimised design of 12/14 DMLPMFSM is presented to validate optimisation procedure.

“…LFSPMM with double mover topology is investigated in [7], whereas [23] examined the performance of a LFSPMM with a double stator topology. Comparison of double stator and double mover LFSM is performed in [24] and the authors claim an advantage of a low thrust force ratio for the DSLFSM structure with moving primary (mover). Analysis and design of a LFSPMM with a yokeless double stator conventional topology is presented in [25,26] and one with multitooth topology is presented in [27,28].…”

Enhancing Capabilities of Double Sided Linear Flux Switching Permanent Magnet Machines

Double sided linear flux switching permanent magnet machines (DSLFSPMMs) exhibit high thrust force density, high efficiency, low cost and robust double salient secondary (stator) structures. The aforementioned unique features make DSLFSPMM suitable for long stroke applications. However, distorted flux linkage waveforms and high detent forces can exaggerate thrust force ripples and reduce their applicability in many areas. In order to enhance thrust force performance, reduce thrust force ripple ratio and total harmonic distortion (THD) of no-load flux linkages, two structure-based advancements are introduced in this work, i.e., asynchronous mover slot and stator tooth displacement technique (AMSSTDT) and the addition of an active permanent magnet end slot (APMES). Furthermore, single variable geometric optimization (SVGO) is carried out by the finite element method (FEM).
