Optimization of axial flux permanent-magnet motors is a very important topic in the literature and requires high performance optimization algorithms and finite element analysis. This paper gives a summary of the analysis methods of axial flux permanent-magnet motors currently available in the literature. An open-circuit model was built and described using the 2D Linear Motor Modeling Approach. The model was validated by comparing air-gap flux-density waveform and cogging torque results with one of the motors described in the literature as a benchmark problem. The aim of the study was to create a method for the axial-flux motor optimization based on the open-circuit finite element model using the Ārtap software. By applying the described method, it is possible to use local and global optimization algorithms, such as evolutionary and genetic algorithms, directly using the finite element analysis results. The proposed finite element model can be used for benchmarking and selecting the most appropriate evolutionary and genetic algorithms for this kind of optimization problems.

PMBLDC motor is a type of brushless motor with a permanent magnet as a rotor material. Its main advantage is high efficiency and high lifetime due to less friction in the operation. Its efficiency can be improved further by the proper selection of BLDC motor design. Based on that, in the existing approach, the finite element analysis (FEA) is carried out using software for finding the stator material and the number of turns. This approach provides the optimal stator material with fixed turns as PMBLDC motor design. But in this, the analysis is carried out only for the two numbers of turns only. Hence, in this, a hybrid optimization approach is proposed for designing the PMBLDC motor. The hybrid optimization selects the pole pairs, thickness winding, and other PMBLDC parameters by minimizing the power loss of the motor. To perform this, here, the moth flame and Cauchy particle swarm optimization are used to determine the optimal PMBLDC parameters using MATLAB R2020b version under a windows 10 environment. The proposed method's performance will be compared with the existing in terms of torque and power loss.

“…With the improvement of modern permanent magnet synchronous motor (PMSM) torque output capabilities, electrodynamic exciters have received great attention recently, and they are widely used in dynamic torsional stiffness tests [4,5]. Compared with moving iron and moving coil motors, the moving-magnet PMSM is characterized by a smaller air gap and a higher torque density, and consequently, it has become the most suitable and common choice for electrodynamic exciters [7,8,9,10,11].…”

“…Thus, to achieve satisfactory dynamic performance by the electrodynamic exciters, the most effective way is to improve torque per inertia by appropriately reducing the gap radius, and increasing the axial length. Compared with conventional PMSMs, disk-type permanent magnet (PM) motors can be designed in a multistage configuration with extreme axial compactness [7]; thus, they are more suitable for high-acceleration applications such as electrodynamic exciters [8,9,10].…”

“…In conventional disk motors, rotor magnet arrays usually introduce axial North-South alternate magnetization arrays with an inevitably thick back-iron to eliminate saturation and to create flux paths, which becomes a bottleneck for improving motor dynamic performance [7,8,9,10,11]. With the help of a Halbach array, which has a high PM working point and self-shielding magnetization, the thickness of the back-iron can be reduced or even removed, reducing the rotor inertia significantly [11].…”

In this paper, a multi-module electrodynamic exciter based on moving-magnet disk voice coil motor is presented to meet the demands of high torque and high bandwidth in a dynamic torsional stiffness test. A variable pole-arc ratio disk Halbach array (VPAR-DHA) is proposed, so that both high torque density and low rotor inertia can be obtained through enhancing the magnetic field in the working range. The analytical quasi-3-D model of VPAR-DHA was set up by using the harmonic function method, with the consideration of end-effects by a correction function. Electromagnetic structure optimization was carried out with the analytical model, and verified by 3-D finite-element (FEM) results. The proposed design was experimentally tested and verified with a prototype that achieved a peak dynamic torque output of 40 Nm at a frequency of 120 Hz, and a stroke of ±1°. The proposed method can also be easily extended to satisfy various demands of dynamic torsional stiffness test.
