“…FSMs can be classified into wounded field FSMs (WFFSMs), permanent magnet FSMs (PMFSMs) and hybrid excitation FSMs (HEFSM), the latter ones combining both field excitation coils and PMs as main flux sources [92]. Different linear FSM topologies have been developed [93], some of them include hybrid excitation, that is, combine three-phase windings and PMs [94,95]. PMFSMs are also being developed using ferrite PMs [96].…”

Several factors including fossil fuels scarcity, prices volatility, greenhouse gas emissions or current pollution levels in metropolitan areas are forcing the development of greener transportation systems based on more efficient electric and hybrid vehicles. Most of the current hybrid electric vehicles use electric motors containing powerful rare-earth permanent magnets. However, both private companies and estates are aware of possible future shortages, price uncertainty and geographical concentration of some critical rare-earth elements needed to manufacture such magnets. Therefore, there is a growing interest in developing electric motors for vehicular propulsion systems without rare-earth permanent magnets. In this paper this problematic is addressed and the state-of-the-art of the electric motor technologies for vehicular propulsion systems is reviewed, where the features required, design considerations and restrictions are addressed.

“…Even if all structures discussed earlier are rotating machines, it should be noticed that hybrid excitation principal has also been applied to the case of linear motion structures [39][40][41]. It should be noticed that many hybrid excitation structures have been also reported in many patent applications [21], [23], [24], [26], [28], [29], [38], [42][43][44][45][46][47][48][49][50][51][52][53][54].…”

This paper describes the state of the art of hybrid excitation synchronous machines. Different hybrid excited synchronous structures from scientific and technical literature are described and analysed. Advantages and drawbacks of the different structures are discussed. Different method of classification of these structures will also be discussed. The contribution of the hybrid excitation principle for motoring and generating mode is detailed and the different models for the design of these structures are presented.

“…Linear flux switching motors (LFSMs) inherit most merits of the rotary flux switching motors (FSMs) that lead to simple and robust structure of secondary, high force density and good thermal management of field excitation module [1][2][3][4][5]. They are classified into two groups that are permanent magnet LFSMs [1][2][3] and field excitation LFSMs [6] which main flux sources are permanent magnet and dc field excitation coils, respectively. Both permanent magnets or dc excitation coils and armature three-phase windings can be mounted on a short mover so that less permanent magnets and copper are used to significantly reduce the cost.…”

A dq model representation of segmented secondary linear flux switching motors (SSLFSMs) is investigated. In these motors, the armature and field windings are both mounted in the primary slots and the secondary is only composed of simple laminated segments. This type of motors inherits both merits of high force density from linear synchronous motors and simple secondary structure from linear induction motors. Due to its simple and consequently low-cost secondary structure, it is applicable to transportation systems like Maglev. Position and speed control of this motor is essential for rail transportation applications. Therefore, derivation of an appropriate analytical model for control purposes is needed. An analytical method to represent the dq model of SSLFSMs is presented. Employing this method, the d-and q-axis inductances and the developed electromagnetic thrust and normal force are calculated. To verify the proposed model, three different finite-element methodbased models are studied and one is chosen as the basis for comparison. All results obtained by the analytical model are verified by this finite-element method-based model. Moreover, a prototype of SSLFSMs is built to validate the study.
