This paper proposes double sided complementary modular field excited flux switching linear machine (FEFSLM). FEFSLM offers the low cost, variable flux capability for a wide speed range, a compact and robust stator which is suitable for the long stroke application. Compared to other linear machines complementary modular design has more sinusoidal and symmetrical flux linkage and lower detent force. Initially, the topology and machine working principle is thoroughly discussed. To maximize the thrust force of the machine and optimize the geometric parameters, built-in genetic algorithm (GA) of JMAG ver. 20 is utilized. Furthermore, the modular design incorporates the concept of fault-tolerant capabilities to provide the required decoupling between phases. 2D finite element analysis (FEA) is used to analyze the machine performance. Comparatively the optimized design exhibits higher thrust force, lower thrust force ripples and higher efficiency than the initial design.INDEX TERMS Flux switching machines, linear machines, genetic algorithm, fault tolerant capability.

Purpose This paper aims to present an overview of permanent magnet linear flux-switching machines (PMLFSM), field excited LFSM and hybrid excited LFSM (HELFSM) topologies as presented in literature for transportation systems such as high-speed trains and maglev systems. Design/methodology/approach The structural designs of different configurations are thoroughly investigated, and their respective advantages and disadvantages are examined. Based on the geometry and excitation sources, a detailed survey is carried out. Specific design and space issues, such as solid and modular structures, structure strength, excitation sources placement, utilization of PM materials, and flux leakage are investigated. Findings PMLFSM provide higher power density and efficiency than induction and DC machines because of the superior excitation capability of PMs. The cost of rare-earth PMs has risen sharply in the past few decades because of their frequent use, so the manufacturing cost of PMLFSM is increasing. Owing to the influence of high-energy PMs and magnetic flux concentration, the efficiency and power density are higher in such machines. PM is the only excitation source in PMLFSM and has constant remanence, limiting its applications in a wide speed operation range. Therefore, the field winding is added in the PMLFSM to flexibly regulate the magnetic field, making it a hybrid excited one. The HELFSM possess better flux linkage, high thrust force density and better flux controlling ability, leading to a wide speed range. However, the HELFSM have problems with the crowded mover, as PM, field excited and armature excitation are housed on a short mover. So, for better performance, the area of each excitation component has to compete with each other. Originality/value Transportation of goods and people by vehicles is becoming increasingly prevalent. As railways play a significant role in the transportation system and are an integral part of intercity transportation. So, this paper presents an overview of various linear machines that are presented in literature for rail transit systems to promote sustainable urban planning practices.
