“…It was shown that by combining the modular winding and multiphase winding techniques, the fault-tolerant capabilities of the machines were greatly enhanced. Owing to the merits of the multiphase winding, the FSPM machines with higher phase numbers, including four-, five-, six-, nine-, and twelve-phase variants were extensively investigated [77][78][79][80][81]. Two five-phase fault-tolerant FSPM machines having 18 and 19 rotor poles were proposed and compared in [82].…”

Permanent-magnet (PM) machines have attracted a lot of interest in various applications since they have the merits of high torque density, high power density and high efficiency. However, issue of poor fault tolerance of the conventional PM machines restricts their practical applications in the field of safety-critical applications, e.g. aerospace, electric vehicle, electrical propulsion and wind power generator applications. An enormous amount of work has been done to improve the faulttolerant capability of PM machines. This paper will review research work on PM fault-tolerant machines up-to-date, including modular design, short-circuit current limitation design, redundant design, ease of thermal dissipation of PM design, and torque enhancement design techniques. The work of this paper can provide some references for future studies and engineering applications of PM fault-tolerant machines for safety-critical applications.

“…This brings benefit of improved magnetic isolation between phases. Building upon this model, effect of phase shift between winding sets and rotor‐pole number on electromagnetic performance of the 12‐phase FSPM machine was investigated in [35] and [36], respectively. It was found that the optimal phase shift for the lowest torque ripple and output rectified voltage oscillation depends on winding types, while symmetrical phase shift is not always appropriate for all occasions.…”

With ever-increasing concerns on energy crisis and environmental protection, there is a fast-growing interest in wind power generation systems. As electric machines and drives are core components in wind turbines, it is a pressing need for researchers and engineers to develop advanced electric machines and drives for wind power generation. This paper provides a thorough review of modern electric machines and drives for wind power generation, with emphasis on machine topologies, operation principles, performance characteristics, as well as control strategies. The key features of electric machines and drives including their merits and demerits, e.g. torque/power density, efficiency, and cost, are compared and summarised. Trade-offs involved in various presented methods and strategies are highlighted. The major challenges and difficulties, which electric machines and drives for wind power generation are facing, are discussed. Moreover, the developing trends and opportunities are revealed, while the latest development is also discussed.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Stator permanent magnet (stator-PM) machines with the PMs and windings mounted on the stator have attracted considerable attention recently as they provide a prospective solution to overcome the shortages of rotor permanent magnet (rotor-PM) machines, such as the complicated rotor structures and heat dissipations [1][2][3] . As a representative of stator-PM machines, flux switching permanent magnet (FSPM) machines have been investigated intensively in the analysis of their operational principles [4][5][6] , new topologies [7][8][9] , and control strategies [10][11][12] . Furthermore, when the number of PMs easily so that the air gap field can be regulated directly and the speed range of the machine is broadened [12][13][14][15] .…”

In this study, the general optimal stator poles/rotor teeth (P/T) combination equation of the E-core hybrid excitation flux switching (HEFS) machines are introduced, and a new HEFS machine is proposed and optimized. Firstly, the influences of three different P/T combinations (10/18, 10/19, and 10/21) on the HEFS machines are investigated with two-dimensional (2D) finite element analyses (2D-FEA). Meanwhile, the consistency and complementarity principle of the armature windings is analyzed in detail to give reasonable explanations to the simulated results. The general optimal P/T combination equation of the E-core HEFS machines is deduced mathematically to provide an effective guidance on the selection of P/T combinations. The optimal P/T combination calculated by the general equation agrees with the simulated results which confirm the correctness of the mathematical inferences.Finally, the optimizations on the proposed HEFS machine are implemented to obtain higher output torque and better flux-regulation ratio characteristics based on which the cogging torque and torque ripple are reduced significantly.
