	Abstract:Compared with the traditional three-phase induction motor, multiphase induction motor not only has the characteristics of high efficiency and high power density, but also has the advantages of small torque ripple and strong anti-interference. Therefore, it has been paid great attention in the application of electric ship propulsion, aircraft drive, locomotive traction and high-power industry. In this paper, a 15kw five-phase induction motor is taken as the research object. Based on Maxwell electromagnetic field theory, the two-dimensional electromagnetic transient field model of five-phase induction motor is established by using finite element simulation software, and solving the problem of the magnetic density, torque and electromagnetic loss of the motor under different working conditions.

	Abstract:In this paper, the electromagnetic performances of a novel axial field flux-switching fault-tolerant (AFFSFT) machine are investigated based on equivalent magnetic circuit (EMC) method. A nonlinear EMC model of the AFFSFT machine is proposed and built, and the static characteristics of the machine, including the air-gap flux density, permanent magnetic flux linkage, back electromotive force (EMF) and inductance characteristics are analyzed. The calculated results are compared with those predicted by finite element method (FEM). Experiments are done with a prototype.

	Abstract:This paper researches a sensorless control method of flux-switching permanent linear magnet with high-frequency signal injection on the basis of salient pole verification, through the analysis of FSPMLM structure. A high frequency sinusoidal voltage signal is superimposed into the estimated d-axis, and the mover position can be demodulated after q-axis current is regulated, which is relative to error angle. Ultimately the mover position and speed can be obtained exactly. The paper also contributes to an improved magnetic pole identification based on space vector pulse width modulation for and arbitrary initial position to resolve starting problem of IPMSM. At last, the simulation model of FSPMLM and control system are constructed and all results of simulation demonstrate the accuracy and effectiveness of the presented approach, this method is well suitable for the application.

	Abstract:A coupled field-circuit method by taking into account the saturation is proposed in this paper. The stator winding inter-turn short circuit and the rotor eccentricity hybrid fault of permanent magnet synchronous generators (PMSG) is analyzed. The harmonic currents were used in order to investigate this kind of fault in a 7.5 kVA PMSG suitable for low-power wind generation applications. Simulation results have shown that the sideband frequency currents at 25 Hz and 75 Hz, and the 17th and 19th order components of terminal currents can be used as fault detection criteria.

	Abstract:To analysis influences under various fault conditions, a fault model of Flux-Switching Permanent Machine (FSPM) under stator winding shorted turn which can be used for a performance assessment of a diagnostic algorithm is presented. For fault conditions of FSPM, turn-to-turn fault and phase-to-phase fault in stator winding are considered in this paper. Even though the conventional d-q coordinate system can be used to construct the model of FSPM, but d - q coordinate system will have a great error under faults. To overcome this limitation, a fault model of FSPM is derived using multi-loop theory. Inductor parameters are obtained by finite element analysis. The accurate fault model provided in this paper lays the foundation for fault diagnosis.

	Abstract:A linear doubly salient permanent magnet (LDSPM) motor is particularly suitable for long stator applications due to its simple and low cost stator, which consists of only iron. This paper proposes a novel LDSPM motor with complementary and modular structure. The key of this structure is that the primary mover are composed of two modules whose positions are mutually four and one half of the stator pole pitch apart and there is a flux barrier between them. Hence, the back electromotive force (EMF) waveform and cogging force of the two modules have 180 electrical degree differences. This results in the total cogging force being cancelled and the back-EMF of each phase becoming symmetrical. For fair comparison, an existing linear LDSPM motor is designed based on the same electromagnetic parameters and compared by the means of finite element analysis (FEA). The results reveal that the proposed LDSPM motor can offer symmetrical back-EMF waveforms, smaller cogging force, lower force ripple and higher magnet utilization factor than the existing LDSPM.

	Abstract:A generating operation for dual-winding switched reluctance generators (DWSRGs) is proposed. Firstly, the generating principle and prototype structure are demonstrated. After that, power converters and excitation strategy are illustrated for the proposed generators. Secondly, the inductance profiles are derived based on the virtual-work method. And the voltage equations of the two windings are also built for the current analysis. Finally, the current expressions for different phases are deduced. The dynamic analysis and experimental results are also obtained to be compared with the calculating results. It is shown that they are in good agreement. After that, the current model is used to depict the relationship between flux-linkage and current. Then the energy conversion is illustrated. The proposed current models can also be employed for machine and power converter design.

	Abstract:This paper investigates the inductance characteristics of a novel 3-phase (12-stator-tooth/10-rotor-pole) flux-switching permanent magnet (FSPM) machine with doubly-salient structure based on finite element analysis (FEA). Firstly, the topology and operation principle of the FSPM machine are introduced. Secondly, the apparent and incremental inductances are defined. Then, the conventional calculation method of transforming the inductance in stator frame into rotor frame is performed. To overcome the shortcoming of the conventional method, e.g. time-consuming, a new simplified and fast method is proposed to obtain the d-axis and q-axis inductances directly and accurately at two special rotor positions. The proposed method is validated by the comparison of the predicted results by two ways.
