“…have been proposed for a wide range of applications such as force actuator [1], precise motion control [2], for propulsion railway transportation systems [3], active vehicle's suspension system [4], life-support applications [5] and in direct-drive wave energy conversion [6]. LSRMs are an attractive alternative to permanent magnet linear motors (PMLM), despite the fact the force/volume ratio is about 60 per cent lower for LSRMs [7].…”

This paper presents an exhaustive study about the influence of some design parameters, such as the number of phases, the pole stroke, and the current density, in the behavior of Linear Switched Reluctance Motor (LSRM). LSRM's performance is assessed taking into account a set of quality indices, which are the energy conversion loop quality factor, the propulsion force per unit of primary steel volume, per unit of copper mass, per unit of air gap surface and finally the force ripple factor. The study is carried out by means of the 2-dimensional Finite Element analysis. Finally, the results are discussed and as a consequence a set of LSRM configurations with optimal performance according to the quality indices is defined.Keywords linear switched reluctance machines, finite element analysis, machine design, and sensitivity analysis.

Analysis and Modeling of Linear-Switched Reluctance for Medical Application

This paper focuses on the analysis, the modeling and the control of a linear-switched reluctance motor. The application under consideration is medical, and the actuator is to be used as a left ventricular assist device. The actuator has a cylindrical or tubular shape, with a mechanical unidirectional valve placed inside the mover, which provides a pulsatile flow of blood. The analytical expression of the effort based on the linear behavior of the actuator is given. The identification of the characteristics of the prototype actuator and the principle of position control is performed. A modeling of the actuator is proposed, taking into account the variation of inductance with respect to the position. The closed-loop position control of the actuator is performed by simulation. A controller with integral action and anticipatory action is implemented in order to compensate the effects of disturbing efforts and tracking deviations. Moreover, a magic switch is performed in the controller to avoid overshoots. The results show that the closed-loop response of the actuator is satisfactory

Abstract.A new type of tubular machine in modular construction that can work either like motor or generator is presented in the paper. It belongs to the transverse flux machines' class and operates based on the variable reluctance principle. Two topologies of the machine, with and without permanent magnets (PM), are approached here. A prototype of the tubular machine with electromagnetic excitation, having a stator core built from laminated sheets and the mover core made of soft magnetic composite material, was built and is shown in the paper. The use of the new soft magnetic composite material, Somaloy 700 HR, having 3D magnetic isotropy, brings important advantages in building the structure. The innovative construction, implying the alternation of the magnetic pieces called modules with no-magnetic spacers, has very good performances. A prototype of this machine was built and a test bench equipped with control and monitoring devices in order to perform experimental tests. Some possible applications showing the potential of the proposed machine are also presented.
