“…A major difficulty for transient simulation is that induced currents on the rotor rings must be calculated in each step before the torque is calculated. Note that finite element method (FEM) facilitates field analysis of electromagnetic problems with complex geometries [27][28][29][30][31][32][33]. The proposed LSAFPM machine has a unique construction, and its lack of symmetry makes 3D-FEA a design requisite.…”

Abstract-This paper presents two design-and-analysis cases of a linestart axial-flux permanent-magnet motor: with solid rotor and with composite rotor. For a novel structure of the motor, two concentric unilevel spaced raised rings are added to the inner and outer radii of its rotors to enable auto-start capability. The composite rotor was coated by a thin (0.05 mm) layer of copper. The basic equations for the solid rotor ring were extracted. The motor's lack of symmetry necessitated 3D time-stepping finite element analysis, conducted via Vector Field Opera 14.0, which evaluated the design parameters and predicted the motor's transient performance. Results of the FEA show the composite rotor significantly improving both starting torque and synchronization capability over solid rotor.

“…When trying to construct an EPS which is fault tolerant, the designing process can be focused either on the power electronic converter, or on the electrical machine structure. The use of poly-phase machines and drives against conventional three-phase machines results in a more fault tolerant system, because when a fault occurs on one or several phases, the machine will still be capable to operate, with acceptable output mechanical performances which are limited only by the windings thermal harshness [7][8][9][10][11]. This is the major advantage of the multi-phase drive-machine system.…”

Abstract-This paper presents the analysis of a six-phase permanent magnet synchronous machine (PMSM6) dedicated for electrical power steering system applications. The motor design is briefly described, as well as the construction of the studied motor. The study is validated by finite element method and via experimental results. Some simulated results prove the machine's capability to work even in faulty conditions. The operation of the machine was evaluated in generator and motor operation. In motor operation, the PMSM6 was fed based on scalar control.

“…This method approaches the problem by reducing errors [18]. FEM is used in different researches for various purposes such as modeling and parameter identification [19][20][21][22][23][24][25]. An acceptable solution from Maxwells equations for most practical cases is neither possible nor accurate.…”

Abstract-Inductive power transfer is recently a common method for transferring power. This technology is developing as the modern technologies need to get more efficient and updated. The power transfer efficiency has potential to get better. There are different ways to achieve a desirable efficiency. In this paper, a suitable geometry of a coil for transferring power as a transmitting coil is examined. In this work, three types of geometries are designed. Frequency analysis at frequency range (10 kHz-50 kHz) is done to investigate behaviour of various geometries. Magnetic field, electric field, magnetic flux density, and current density for various geometries are presented and compared. Magnetic flux density is measured via an experimental setup and is compared to simulated one to verify the validity of simulation results.
