“…Figure 2 shows the different topologies for stator core and the different topologies for an inner mover as well (Poltschak and Kobleder, 2015). For both single-phase C-core and E-core tubular MMLOA, alternative design topologies are proposed in Zhu et al (2008), Jiao et al (2016), Abdalla et al (2018), Alberto et al (2020), Just et al (2019), Petrov et al (2020) and Chen et al (2008).…”

Purpose This paper aims to provide an overview of the recent developments and new topologies of single-phase moving magnet linear oscillating actuators (MMLOAs). The key advantage of the MMLOA when compared with conventional LOA is the absence of screws, gears and crankshaft mechanism, which results in fewer mechanical parts, simple structure, easy fabrication, lower noise levels and negligible frictional losses. Design/methodology/approach The review included papers up to August 2021. The structural designs of alternative topologies are deliberated in detail, and their relative merits and demerits are evaluated. Specific design issues, including pole and tooth number combinations, stroke length, magnet pole ratio and split ratio, are investigated. The imperative phenomena of the resonance, as well as the adjustable stroke, are also discussed in detail. Findings The electromagnetic performance in terms of thrust force of selected MMLOA topologies is compared. It is observed that the MMLOA with flux bridge topology has the highest thrust force of 365 N because of the large volume of the permanent magnets (PMs) used, which consequently increased the mass of the mover but based on overall performance analysis, single-phase end ferromagnetic Halbach surface-mounted PM LOA has the highest efficiency around 92%. Originality/value This review provides a comparative analysis for different tubular MMLOA topologies based on design construction and their electromagnetic performances.
