Abstract. This paper presents an analytical approach to the design of a high-force density double-sided linear switched reluctance motor (LSRM). The design is based on an analytical formulation of the average propulsion force determined using the non-linear energy conversion loop, in which the unaligned magnetization curve is assumed to be a straight line and the aligned magnetization curve is represented by two straight lines. The main dimensions of the LSRM are determined in accordance with the machine requirements, the proposed average propulsion force formula and the geometrical relationships that were presented in a previous paper. The present paper uses two dimensional finite element analysis that has been corrected to take into account the end effects in order to refine and/or to validate the proposed design. Finally an LSRM prototype was built following the proposed design and was verified by experimental measurements.

This paper describes a new linear switched reluctance motor (LSRM) with a light and easily replaceable mover. The proposed LSRM has coils at both ends of the stator so as to have a thin shape, which is important for systems with a limited work space. The mover has a simple and thin shape, leading to easy fabrication and space savings. It is made from common materials and is easily recyclable. The flat areas on the surfaces of the mover and stator are used as a slide guide. The prototype LSRM has a thickness of 2.4 mm, and the thickness of the mover is 0.27 mm. The suitable driving signal for the proposed LSRM is determined from the numerical magnetic analysis results. The prototype LSRM shows a velocity higher than 285 mm/s and an acceleration higher than 3 m/s 2 .

“…A high force longitudinalflux double-sided double-translator LSRM has been analyzed in (Deshpande et al, 1995). Longitudinal-flux LSRMs have been proposed for applications such as precise motion control (Pan et al, 2005;Zhao et al, 2007) and as propulsion systems for railway vehicles (Kolomeitsev et al, 2008) or vertical elevators (Lim and Krishnan, 2007;Lim et al, 2008;Lobo et al, 2008). Recently, a detailed sensitivity analysis of double sided LSRM parameters based on (Arumugam et al, 1988) has been presented in (Amoros and Andrada, 2010).…”

Abstract:The important problems to be solved in Linear Switched Reluctance Machines (LSRMs) are: (1) to design the shape and size of poles in stator and translator cores; (2) to optimize their geometrical configuration. A novel stator geometry for LSRMs that improved the force profile was presented in this study. In the new geometry, pole shoes were affixed on the stator poles. Static and dynamic characteristics for the proposed structure had been highlighted using Two Dimensional (2-D) Finite Element Analyses (FEA). Motor performance for variable load conditions was discussed. The finite element analyses and the experimental results of this study proved that, LSRMs were one of the strong candidates for linear propulsion drives. Problem statement: To mitigate the force ripple without any loss in average force and force density. Approach: Design modifications in the magnetic structures. Results: 2-D finite element analysis was used to predict the performance of the studied structures. Conclusion/Recommendations: The proposed structure not only reduces the force ripple, also reduced the volume and mass. The future study is to make an attempt on vibration, thermal and stress analyses.
