“…These works can be divided into three categories. In the first group, finite‐element analysis (FEA) is employed ; in the second group of papers, mathematical model of the motor is considered and in the last group, equivalent circuit of motor is employed to predict its performance . However, it is to be noted that almost all of the previous works regard three phase AFIMs with solid disk rotors, and there is no paper on performance characteristic of laminated squirrel cage single‐phase induction motor (except ).…”

The objective of this paper is to investigate the torque-speed characteristics of single-phase axial flux squirrel cage induction motors using a two-dimensional (2-D) electromagnetic field analysis. In this study, the effect of saturation and anisotropy of electromagnetic cores is taken into account. Furthermore, the effect of harmonics is considered in the analysis. Then, 2-D and three-dimensional time-stepping finite-element (FE) analysis is employed to validate theoretical results. Finally, the motor prototype is constructed and tested. Good agreement between analytic, FE and experimental results shows the accuracy and success of proposed model.

“…Accordingly, by the spread of AFIM applications, several papers have been published recently, related to these motors. References [3,[5][6][7][8][9][10][11] dealt with AFIM design and [4,[12][13][14][15][16][17][18] analysed their performance by various modelling methods; though most of them addressed AFIMs with solid iron rotors. The electromagnetic performance of solid iron rotor is notably weaker than the laminated one, while it is superior in high-speed applications due to its more mechanical robustness [9].…”

Using a dual air-gap structure in a disc-type motor is an effective solution to eliminate undesirable axial force between stator and rotor, by which higher power density can be achieved, too. Furthermore, some of the performance characteristics such as pulsating torque may be improved greatly by adjusting the existing extra selective design parameters in a dual air-gap motor. Accordingly, in this study, a widespread design consideration is carried out on rotor skewing arrangements of a dual rotor (DR) axial flux induction motor with the aim of pulsating torque reduction. The studied scenarios include when the slots of both rotors are skewed exactly similar with different skew angles, the slots of both rotors are skewed similarly but in the opposite directions and the slots of both rotors are not skewed but one rotor is mounted on the shaft by some shift angle relative to the other. The last one is introduced as an alternative to skewed rotors, which is easily executable in small and large size motors with DR topology. Moreover, an algorithm is proposed to determine the appropriate shift angle. Three-dimensional time stepping finite element analysis is employed in all cases for verification.

“…Some other advantages of axial flux machines are planar and adjustable air gap, better power-to-weight and diameter-to-length ratios, compact construction and better efficiency [6,7]. Considering all these features, there are many papers dealing with the analysis and performance prediction [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] or design and manufacturing of AFIMs. In earlier groups, most of the literature has described quasi-three-dimensional (3D) mathematical models or finite-element analysis (time harmonic or magnetostatic solution).…”

The aim of this study is to find out the performance characteristics of single-phase axial flux induction motors. In this study, three-dimensional time-stepping finite-element method is employed to analyse electromagnetic fields. Both eddy current and saturation effects are considered in the simulation. Since this transient solution is a computationally expensive method, a mathematical model based on d−q-axis theory is presented in this study. Then, the motor's electrical parameters, whose values are requested in the d−q model, are calculated using the analytical method and the DC-charge test of the built motor. The comparison between experimental and simulation results verifies the success of simulation.
