“…The 3-D FEA is generally recognized as the most accurate numerical tool for solving Maxwell equations of each volume element under boundary conditions, so the electromagnetic modeling based on FEA are widely used [64][65][66]. Some references [67][68][69] compared the solutions of the proposed new model with the results of 3-D FEA analysis to verify the rationality as well. However, the 3-D FEA method takes a long computational time, which is difficult to adapt to the modeling and analysis of complex AFPM motors' topological structure.…”

Axial-flux permanent-magnet (AFPM) motors are a kind of important motor with compact structure, high power density and high torque density. In this review, the progress of AFPM motors and their key technologies are analyzed and described, with emphasis on the topological structures, design and optimization methods and control techniques. Based on these analyses, the main findings of the review are the following: (1) the yokeless and segment armature (YASA)-type motors have great potential for development; (2) the multi-objective optimization design theories can be integrated and applied to optimize the design of AFPM motors; and (3) optimal control and sensorless control have important value in improving system reliability and reducing cost. Finally, highlights and prospects are provided for further advancing AFPM motors.

“…After that, the flux density, magnetic field intensity, phase flux linkage, and electromagnetic torque can be determined. The MEC technique is usually utilized to provide preliminary designs [92][93][94][95] and to analyze the electromagnetic characteristics [91], [96], [97] of SRMs. This technique is divided into two approaches: conventional MEC approach [98][99][100] and reluctance-mesh/finite-reluctance approach (FRA) [101][102][103][104].…”

Switched Reluctance Machines (SRMs) are gaining more attention due to their simple and rugged construction, low manufacturing cost, and high-speed operation capability. An electromagnetic model of the machine is needed in the design and analysis processes. The required accuracy level of the model depends mainly on the application. A high-fidelity model is required to achieve a good design and predict the performance accurately. However, it requires high computational cost and longer simulation time. Other fast and less-comprehensive models with less computational burden could be utilized in the design and analysis of the motor drives. This paper extensively analyzes various electromagnetic modeling techniques of SRMs. Analytical, numerical, and hybrid models are considered. The paper investigates analytical models that are based on Maxwell's equations in addition to interpolation and curve fitting techniques. Numerical techniques such as Finite Element Method (FEM) and Boundary Element Method (BEM) are presented. Moreover, Magnetic Equivalent Circuit (MEC) method is discussed. Finally, potential research areas are proposed for the electromagnetic modeling of SRMs. INDEX TERMS Analytical model, boundary element method (BEM), electromagnetic modeling, finite element method (FEM), magnetic equivalent circuit (MEC) model, numerical model, switched reluctance machine (SRM).

“…However, because the permanent magnets are located on the rotor, the cooling conditions are poor and the heat dissipation is difficult, which leads to irreversible demagnetization of the permanent magnets, which affects the motor operation and power density. Therefore, stator permanent magnet motors, double salient permanent magnet (DSPM) motors and flux switching permanent magnet (FSPM) motors have been extensively studied in recent years [1][2][3][4].…”

“…Although the mathematical model of the 12/10 pole permanent magnet flux switching motor and the rotor permanent magnet synchronous motor (BLAC) are the same [1][2][3], the rotor has a salient pole structure without permanent magnets and windings. An initial position detection and sensorless control of a 6Slotes/4Poles FSPM motor is presented in [16].…”

Flux-switching permanent magnet (FSPM) machines are novel brushless machines having magnets in the stator and currently are under intensive research due to their novel features, such as simple and robust rotor, flux focusing effect, sinusoidal phase back-EMF, high torque/power density and high efficiency. In this paper, a sensorless high-frequency sinusoidal signal injection scheme for a novel yokeless and segmented armature axial flux-switching sandwiched permanent-magnet motor (YASA-AFFSSPM) is proposed. Firstly, pulsating voltage injection is investigated in detail. In addition, a simpler method (Direct signal process method) for position error signal processing is presented based on pulsating signal injection. The principle and the realization of this method are analyzed in depth. Through experiment, the traditional signal process method and direct signal process method with high-frequency pulsating sinusoidal signal injection are compared to verify the validity these methods.
