“…Feature-wise, linear switched reluctance machines (LSRMs) are very similar to LIMs. Their main advantages are their low material and manufacturing cost [53]- [55], simple structure [57], [64], [66], and their inherent ruggedness [61], [64]- [66].…”

“…6. The low number of elements makes these machines very easy to manufacture [60], [63], and their wide constant power operating range [53], [58], has made them an interesting candidate for their application in elevators [43], [57], [65] or rail transit applications [53].…”

“…This makes them highly reliable and fault tolerant [44], [46], [57], [59]. 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.

“…This motor has been under research since its advent because of its inherent advantages. The LSRM possess advantageous features such as rugged and cheap construction because of having windings either on the stator or on the translator, capability of producing high propulsion force without using any PMs, more fault tolerance because of phase independence [41][42][43][44][45][46][47][48][49]. However, it also suffers [46][47][48][49].…”

Consistently rising environmental concerns and depleting petroleum resources have accentuated the need of sustainable, energy efficient and clean means of transport. This has provided the impetus to the research and development of clean alternatives for existing public transportation systems. Development of linear motor-propelled, contact-less maglev systems is considered a promising alternative to conventional on-wheel rail transport technology. Maglev technology primarily focuses on improving the performance, speed, fuel economy, driving range and operating cost of the transit system. These parameters vary with the design and efficiency of the electrical system used in maglev-based transportation systems. To present this study, firstly, a detailed survey of the important constituents of a maglev electrical system has been carried out with techno-economic perspectives. Contemporary maglev technologies have then explored along with their respective advantages and limitations. Electrical systems form the heart of maglev systems and, therefore, this paper presents the components of a standard electrical system together with the comparative analysis in terms of present trends, ongoing technological advancements and future challenges.
