“…They are also capable of achieving higher thrust densities than LIMs [53], [59], while lowering thermal management requirements on their secondary side [48], [49]. Even so, their thrust capability is still lower than the one from LPMSMs [51], [65], [127].…”

This document reviews the current state of the art in the linear machine technology. First, the recent advancements in linear induction, switched reluctance and permanent magnet machines are presented. The ladder slit secondary configuration is identified as an interesting configuration for linear induction machines. In the case of switched reluctance machines, the mutually-coupled configuration has been found to equate the thrust capability of conventional permanent magnet machines. The capabilities of the so called linear primary permanent magnet, viz. switched-flux, flux-reversal, doubly-salient and vernier machines are presented afterwards. A guide of different options to enhance several characteristics of linear machines is also listed. A qualitative comparison of the capabilities of linear primary permanent magnet machines is given later, where linear vernier and switched-flux machines are identified as the most interesting configurations for long stroke applications. In order to demonstrate the validity of the presented comparison, three machines are selected from the literature, and their capabilities are compared under the same conditions to a conventional linear permanent magnet machine. It is found that the flux-reversal machines suffer from a very poor power factor, whereas the thrust capability of both vernier and switched-flux machines is confirmed. However, the overload capability of these machines is found to be substantially lower than the one from the conventional machine. Finally, some different research topics are identified and suggested for each type of machine.

The use of power electronic converters is essential for the operation of Switched Reluctance Machines (SRMs). Many topologies and structures have been developed over the last years considering several specific applications for this kind of machine, improving the control strategies, performance range, fault-tolerant operation, among other aspects. Thus, due to the great importance of power electronic converters in such applications, this paper is focused on a detailed review of main structures and topologies for SRM drives. The proposed study is not limited to the classic two-level power converters topologies dedicated to the SRMs; it also presents a review about recent approaches, such as multilevel topologies and based on impedance source network. Moreover, this review is also focused on a new class of topologies associated to these machines, namely the ones with fault-tolerant capability. This new category of topologies has been a topic of research in recent years, being currently considered an area of great interest for future research work. An analysis, taking into consideration the main features of each structure and topology, was addressed in this review. A classification and comparison of the several structures and topologies for each kind of converter, considering modularity, boost capability, number of necessary switches and phases, integration in the machine design, control complexity, available voltage levels and fault-tolerant capability to different failure modes, is also presented. In this way, this review also includes a description of the presented solutions taking into consideration the reliability of the SRM drive.

“…The stator yoke makes it impossible to modular the rails but integrate the stator as a whole structure which incur assembling problem. A segmental structure has been proven to be very effective to overcome this issue by using series of concrete segments without any mechanical connections [6]. Moreover, it can significantly increase the force density because the segmental structure get rid of the constraint of pole arc to pole pitch ratio ＜ 0.5 and significance enhances the flux carrying ability.…”

Linear switch reluctance machine (LSRM) has been a promising candidate for long rail linear transmission driving system as it exhibits low manufacturing cost. As its counterpart rotary SRM, LSRM has lower force density particularly with larger airgap. A new kind of hybrid excitation LSRM with both magnetic excitation and winding current is presented in this paper. The presented machine incorporates concrete ferritemagnetic segmentations and magnets housed in the translator slot. The topology details of presented machine are given. The performance in terms of static force profile and flux linkage with various excitation current are compared to the machine with pure current excitation.
