“…But, it has to be mentioned that most of these studies are predominantly in terms of high-speed traction drives, with exceptions based on studies by Amara et al (2005) [54] and Thomas et al (2008) [63] for aerospace applications, Sulaiman et al (2016) [72] for an electric boat, Chen, Nilssen and Nysveen (2010) [66] for downhole applications, and Hwang et al (2016) [52] for an elevator door. With regards to HS wind generator drives, not so much is on record in terms of designs based on FSMs.…”

“…However, since the polarity of the magnetic field generated by two adjacent excitation coils is opposite, as is shown in Fig. 2(b), the excitation magnetic flux self-loop is generated, which greatly reduces the torque output capacity of the machine [26]- [28]. To further improve the output torque, the 12-stator-tooth nonoverlapping stator wound field synchronous (N-SWFS) machine was proposed by changing the orientation of the excitation coils to be consistent [29], as is shown in Fig.…”

In this paper, based on the conventional nonoverlapping stator wound field synchronous (N-SWFS) machine, a novel multi-excitation-tooth N-SWFS (MN-SWFS) machine is firstly proposed by changing winding configurations and the excitation-teeth shape. The electromagnetic performance of four optimized MN-SWFS machines sharing the same 12-stator-teeth but different rotor-teeth numbers, namely 12/10, 12/11, 12/13, and 12/14, is compared by finite element analysis (FEA). The corresponding simulation results show that 12/10 and 12/14 are the optimal stator-teeth/rotor-teeth combinations due to much smaller back electromotive force (back-EMF) THD and torque ripple (Trip). Finally, a series of comparative studies are carried out on the proposed MN-SWFS machines and the conventional N-SWFS machines. The comparative results validate that the proposed 12/10 and 12/14 MN-SWFS machines exhibit better electromagnetic performance than the conventional 12/11 and 12/13 N-SWFS machines, such as higher fundamental back-EMF amplitude and greater torque output capability, though their cogging torque (Tcog) and torque ripple are slightly higher, and the torque anti-saturation ability is slightly weaker.

“…Currently, studies on FEFSM are being conducted by researchers as their cost of construction is low and no need to worry about the ever-depleting supply of rare earth PMs. In this regard, three-phase FEFSM with salient rotor is considered the most suitable candidate for high speed applications because of their advantages of flux controllability, and robust due to single piece of rotor structure [11], [12].

Field excitation flux switching machines (FEFSMs) in which their torque performance generated by interaction between armature and field excitation (FE) coils have been widely designed and developed for various applications. In this regard, FEFSM with salient rotor is considered the most suitable candidate for high speed applications because of their advantages of flux controllability, and robust due to single piece of rotor structure. However, the existing FEFSM with overlapped armature and FEC windings lead to increment of copper loss, motor size and material cost. In addition, the declination of torque and power densities due to high rotor weight needs to be improved. In this paper, performance comparisons of four FEFSM topologies particularly emphasis on non-overlap armature coil and FEC windings placed on the stator with segmental rotor are investigated. The performances, including flux linkage, back-emf, flux strengthening, flux line, flux distribution, cogging torque, torque and power of the proposed motor are analysed and compared using 2D finite element analysis (FEA) thru JMAG Designer version 15. As a result, segmental rotor has produced shorter flux paths, while non-overlapping windings has reduced the copper consumption. Finally, the best combination of stator slot-pole configurations is 12S-6P which provide high flux linkage, high torque and power of 0.0412 Wb, 0.77 Nm and 0.26 kW, respectively.
