“…The reason is to reduce the PM cost due to the increasing price of PM since 2011, (iii) Generally, it is expected that the longer the PM depth will produce more flux and enhance the overall performances, therefore in this design the PM depth is set approximately one third of the stator depth. However, demagnetization effect on the PM edge needs to be taken into consideration when higher PM depth is applied, (iv) The slot area of DC FEC is set to 197.01 mm 2 to give a maximum current density, Je of 30 A/mm 2 with 44 turns of FEC winding. The FEC slot depth is less than the PM depth to give an appropriate distance between the adjacent FEC slots area for the flux to flow in this area, (v) The depth of armature slot area is set similar to the PM depth in order to avoid overlapping between armature coil winding and FEC winding.…”

“…The FSM was first introduced in the mid of 1950's and well known as singlephase generator or alternator [1]. Obviously, since ten years ago, many novel and new topologies of FSMs have been established and enriched for better performances applied in various applications such as in wind power generator, automotive system, aerospace, traction drive as well as in low cost domestic appliances [2][3][4][5]. There are three categories of FSMs known as permanent magnet (PM) FSMs, hybrid excitation (HE) FSMs, and field excitation (FE) FSMs.…”

-Flux switching machines (FSMs) with the advantages of single piece of rotor and robust rotor structure become a popular research topic in recent years that suitable for various speed conditions. This machine combined the advantages of Switched Reluctance Machines (SRMs) and Permanent Magnet Synchronous Machines (PMSMs). Previously, most of developed FSMs are mainly focused on inner-rotor configuration, and hard to find research on outer-rotor FSM configuration. Therefore, this paper presents design investigation of three phase Hybrid Excitation Flux Switching Machine (HEFSM) with outer-rotor configuration. Primarily, design processes of the outer-rotor HEFSM especially for drawing parts, materials and conditions used, and properties setting are described in detail. Next, coil arrangement tests are also evaluated to confirm the principle operation of the machine and the phase sequence of each armature coil. Finally, DC field excitation flux capabilities at various current density condition, flux path and flux distribution, back-emf voltage and initial torque are also investigated.

“…FSM can be classified into three bunches that are Permanent magnet (PM) FSM, Field Excitation (FE) FSM and Hybrid Excitation (HE) FSM. Permanent magnet and field winding are the fundamental sources of flux in PMFSM and FEFSM, respectively while in HEFSM, both field winding and permanent magnet produces the flux [1]- [4]. In all these FSMs the armature winding and field winding or Permanent magnets are found on the stator.…”

Recently, a three-phase Field Excitation Flux Switching Motor (FEFSM) with salient rotor structure has been introduced with their advantages of easy rotor temperature elimination and controllable FEC magnetic flux particularly meet for high torque, high power as well as high speed diverse performances. Nevertheless, the salient rotor structure is found to lead a longer magnetic flux path between stator and rotor producing weak flux linkage along with low torque performances. Therefore, a new structure of a single-phase FEFSM using segmental rotor with non-overlap windings is proposed. Segmental rotor and non-overlap windings are the clear advantages of these topologies as the copper losses gets reduce and rotor becomes less weight as well as more robust. Detailed analysis on winding arrangement test analysis, armature and FEC flux linkage, back-EMF and average torque characteristics have been performed by using 2D Finite Element Analysis (FEA) through JMAG version 15 software. The results show that the proposed motor with segmental rotor and non-overlap windings produce short flux path, high flux linkage and the highest torque capability achieved is 0.91 Nm.

“…The total flux generation is limited because of adjacent DC field excitation coil isolation, as marked by red circles and thus machine performance is affected. To overcome the drawbacks, a new structure of 24S-10P and 24S-14P WFSalR SFM with single DC polarity have been introduced and compared as depicted in Figure 2 [8]. Although less leakage flux and uncomplicated manufacturing of single DC FEC are the advantages of proposed machine, but it has overlapping armature and field windings which increases the cost, copper losses and thus reduce the efficiency.…”

In this paper, a new wound field salient rotor (WFSalR) switched-flux machine (SFM) with 12 stator poles and 10 rotor poles is designed, investigated, and compared with the same stator but 8 rotor poles WFSalR SFM. The main advantage of these SFMs when compared with induction machines, direct current (DC) machines etc is that, all the active parts such that armature coil and field excitation coil (FEC) are located on the stator while the rotor part consists of only single piece iron. This makes the machine more robust, simple structure and more suitable to be used for high speed applications. Concentrated windings at the stator reduce the copper consumption and also the copper losses. Initially, the general construction of WFSalR SFMs and design specifications are outlined. Then, finite element analysis (FEA) is used to investigate and compare the flux linkage, induced emf, cogging torque, average torque and torque speed characteristics of proposed WFSalR SFMs.
