This paper explains the high reliability of a segmental stator for fault-tolerant of Switched-Flux Permanent Magnet Machines (SFPMMs). The advantage of SFPMMs when compared to induction machines (IMs) and switch reluctance machines (SRMs), is because it has the most power dense, excellent overload capability and the machine structure is designed to limit fault current. High power and torque output give reasons to the SFPMM to be solely selected to obtain a full torque needed and high-power factor at high speed region compared to SRM which have a limited torque, power and low maximum speed operation. Therefore, the theoretical and technical literature of the common cause of electric motor are discussed. In this paper, it is explained briefly about the proposed segmental stator 12Slot-12Pole SFPMM, flux linkage analysis, back-emf, cogging torque, torque and power output performance in 30Arms/mm2 armature current density. Further-more, this paper explains the advantages of segmental stator specifically as fault tolerance in stator winding such as line-to-line, line-to-ground and three phase faults. Moreover, this paper discussed about the source of failure for the machine itself and what is the minimum reliability requirements of a fault-tolerant machine.

This paper presents a comparison between single-phase 12S-6P and three-phase 12S-10P field excitation flux switching machine (FEFSM) with non-overlap windings and salient rotor. Based on the previous designs, three-phase FEFSM and single-phase FEFSM have been developed with the overlap windings between armature and FEC which create problems of high end coil, increase the size of the motor and high copper losses. Moreover, the previous designs has odd number of pole caused unbalance magnetic forces. Therefore, a single-phase 12S-6P FEFSM and three-phase 12S-10P FEFSM with nonoverlap windings and salient rotor is introduced to reduce the coil end problem. In this study, the operating principle of singlephase and three-phase salient rotor is also investigated. Then, flux line, flux distribution, induced voltage, torque and power versus speed validated with 2D-finite element analysis.

Permanent magnet flux switching machine (PMFSM) has the benefits of a robust design structure, high efficiency, and high torque density. The way to improve the performance and reduce the cost of the machine by selection of pole and slot number is an important issue to be solved. This paper presents a complete performance comparison of a PMFSM design motor with different combinations of slot and pole numbers. Under the same machine diameter and volume of permanent magnet, the flux linkage, unwanted/cogging torque, back-electromotive force (EMF), output torque and power performance are investigated and compared. The results display that the combinations of slot and pole numbers have a major impact on the performance of motor design. Four PMFSM motor design configurations, namely motor 1 with 4S-8P, motor 2 with 8S-16P, motor 3 with 10S-20P and motor 4 with 12S-18P are compared to observe the best one for electric bicycle application. 2D finite element analysis (2D-FEA) with JMAG Designer version 14.1 is used to perform the analysis. Simulation result displayed the 4S-8P PMFSM structure has produced 4.1Nm, compared with the other three designs namely 8S-16P at 1.8Nm, 10S-20P, and 12S-18P at 2.15Nm and 0.48Nm respectively. Motor 1 by 4S-8P illustrated a valuable opportunity to achieve the target performances compared to rest of other selected motor and will be even better in the future. The results of the comparison show that motor 1 with 4S-8P is the best selection according to the criterion of maximum torque performance. However, it is found that high back EMF under no load condition due to the high flux linkage. Therefore, through greater refinement and optimization of the design in the selected configuration of the stator pole and the rotor, it is expected to achieve the target performance of the PMFSM design.

The main advantages of field excitation flux switching motor (FEFSM) are high power, simple structure and, robust rotor, making it very suitable for high-speed applications. However, the previous single-phase FEFSMs using overlap winding and salient rotor have high rotor weight, low torque and low efficiency need to be improved. In this paper, a new structure of single-phase non-overlap winding FEFSMs using salient (SalRoN) and segmental (SegRoN) rotors are proposed. The proposed motors are designed and analysed by 2D-FEA via JMAG Designer version 15. Performances verification is conducted by comparing the various magnetic flux characteristics, torque at multiple combinations of armature current and field excitation current, and torque-power versus speed profiles. In short, the SegRoN design has produced power, initial torque and based speed of 277.5 W, 0.91 Nm and 2,899 rpm which are higher than SalRoN design of 3.2 times, 2.1 times, and 63.9%, respectively. As a conclusion, performances of the proposed non-overlap windings FEFSMs have been successfully compared, SegRoN design having high potential to be applied for lightweight applications.

Interior Permanent Magnet (IPM) motor has been widely used in a range of industrial application due to high power density and good flux-weakening capability. In many of the applications, the high strength of permanent magnets causes the undesirable effects of high cogging torque that can aggravate performance of the motor. Large cogging torque is significantly produced by IPM motor due to the similar length and the effectiveness of the magnetic air-gap. Therefore, the reduction of cogging torque becomes an inreasingly vital subject in IPM motor. In this paper, to minimize the effect of cogging torque in IPM motor, four common techniques for cogging torque reduction such as skewing, notching, pole pairing and rotor axial pole pairing has been analyzed in order to compare the cogging torque effect. 3D finite element analysis (FEA) by JMAG software is carried out for each technique. The results showed the reduction of cogging torque up to 99%, followed by 81.90%, 43.2% and 39.01% compa...

Wound-field switched-flux machines (WFSFM) have an intrinsic simplicity and high speed that make them well suited to many hybrid electric vehicle (HEV) applications. However, overlap armature and field windings raised the copper losses in these machines. Furthermore, segmented-rotor configuration is employed to enhance the characteristics of motor, however it made the rotor less robust and cannot be applied in high speed applications. To overcome these problems, this paper presents novel topologies for three-phase wound-field switched-flux machines. Both armature and field winding are located on the stator and rotor is composed of only stack of iron. Non-overlap windings and salient rotor are the clear advantages of these topologies as the copper losses gets reduce and rotor becomes more robust. Design feasibility and performance analysis of 12 slots and different rotor pole numbers are examined on the basis of coil arrangement test, peak armature flux linkage, back emf and cogging ...

Salient rotor field excitation flux switching synchronous motor (FEFSSM) could be considered as the most feasible candidate in high speed condition owing to their robustness and flux control ability. Nevertheless, the existing FEFSSM utilizes overlapped field excitation coil (FEC) and armature windings, the material cost, motor size and rise of copper loss should be overcome. Besides, deterioration in power and torque densities due to salient structure of rotor weight needs to be improved. In this research, the salient rotor and overlapped windings in conventional FEFSSM are replaced with segmented rotor and non-overlap winding configuration, respectively. Initially, design structures of four FEFSSM topologies i.e., 12S-3P, 12S-6P, 12S-9P and 12S-15P are conducted using 2D finite element analysis (FEA). Then, performances in term of flux linkage, induced voltage, flux enhancement, flux lines and distributions, allowable cogging torque, average torque and maximum power are analyzed. ...

Diverse topology of three-phase and single-phase Field Excitation Flux Switching Machines (FEFSMs) that have been developed recently have several advantages such as variable flux capability and the single piece structure of rotor suitable for high-speed applications. However, a salient rotor structure has led to a longer flux path resulting in high flux leakage and higher rotor weight.

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.

The recent change in innovation and employments of high-temperature magnets, permanent magnet flux switching machine (PMFSM) has turned out to be one of the suitable contenders for seaward boring, however, less intended for downhole because of high atmospheric temperature. Subsequently, this extensive review manages the design enhancement and performance examination of external rotor PMFSM for the downhole application. Preparatory, the essential design parameters required for machine configuration are computed numerically. At that point, the design enhancement strategy is actualized through deterministic technique. At last, preliminary and refined execution of the machine is contrasted and as a consequence, the yield torque is raised from 16.39Nm to 33.57Nm while depreciating the cogging torque and PM weight up to 1.77Nm and 0.79kg, individually. In this manner, it is inferred that purposed enhanced design of 12slot-22pole with external rotor is convenient for the downhole application.

In the past, 4S-10P E-Core Hybrid Flux Switching Motor (HFSM) had been studied. However, the motor suffers high cogging torque but it has high performance in terms of high power and high torque at high speed. Therefore, this paper is proposing the cogging torque reduction techniques to minimize the cogging torque. The high cogging torque gave an undesirable effect during low operating speed of the motor. In order to tackle the issue, the cogging torque mechanism in equation is laid out as a form of reference. Then the reduction techniques employed on the designs and analyzed with Finite Element analysis (FEA) in JMAG. The results show the cogging torque of the optimized design is 44.45% of the motor torque. Besides, the techniques employed to identify which techniques gave the most cogging torque reduction and analyzed the geometrical difference using the cogging torque mechanism. Finally, the analysis is discussed based on the modified geometrics.

This paper present a comparative study of single-tooth and multi-tooth stator of 4S-8P permanent magnet Flux Switching Machine (FSM) for electric bicycle application. Detailed comparison of the performance characteristics of the machines are presented that include important issues such as average torque, volume of PM, back-EMF and speed performance. For a fair comparison, the valid stator slot and rotor combinations is same dimension and analyzed using finite element analysis, and the one among of the design has the best electromagnetic performance is selected. On the basis of the investigation, it can be concluded that the single-tooth design of proposed permanent magnet FSM for a single phase 4S-8P topology has presented higher torque performance compared to multi-tooth design. However, since design of single-tooth exhibits a higher back-EMF, Design optimization and improvement structural is ongoing to achieve the best performance.
