“…However, the resulting larger magnetic air gap and the heat dissipation of the windings limit its applications. Yokeless stator AFPMs having fractional slot concentrated winding (FSCW) and integrated slot distributed winding (ISDW) are comparative studied for electrical vehicle traction applications [25]. The comparative results shows that the ISDW-AFPM machines with IPM structure exhibit better both the torque/power capacity and the flux weakening capacity.…”

“…With the development of electrical vehicles, in-wheel traction has recently become an important research hotspot [1,2]. This application requires a small un-sprung weight, and the traction machine should meet the performance requirements in the limited installation volume [3,4]. Compared with radial flux permanent magnet (RFPM) machines, axial-flux permanent magnet (AFPM) machines with yokeless and segmented armature (YASA) topology have the advantages of less mass and more efficiency, which are suitable for in-wheel traction application, especially in limited axial dimensions [5][6][7].…”

For electrical machines with complex structures, the design space of parameters can be large with high dimensions during optimization. Considering the calculation cost and time consumption, it is hard to optimize all the design parameters at the same time. Therefore, in that situation, sensitivity analysis of these design parameters is usually used to sort out crucial parameters. In this paper, the sensitivity analysis-based Taguchi method is applied to optimize the axial-flux permanent magnet (AFPM) machine with yokeless and segmented armature (YASA) topology for an in-wheel traction system. According to the key parameters and their sensitivity analysis, the optimal machine scheme to meet the performance requirements can be formed. In this case study, the machine performance is improved significantly after optimization. Lastly, the experimental results verify the accuracy of the model used in this study.

This paper presents a 3-D analytical model of an axial-flux permanent magnet (AFPM) machine with a segmented multipole-Halbach PM array. Closed-form solutions are self-consistently derived in terms of modified Bessel functions of the first-and the second-kind by solving analytically Laplace and Poisson equations by the method of magnetic scalar potential subject to the appropriate boundary conditions. In the preceding studies, their formulations are based on 2-D or quasi 3-D geometry, and their discussions are often limited to the magnetic fields with the low-poles of the regular PM. The proposed model successfully provides more rigorous and widely applicable expressions for magnetic fields, back-electromotive force, Lorentz torque and torque constant without limitations on the number of poles and the arrangement of the PMs. Behavior of the torque constant is then shown against the number of poles ranging widely from low-poles to high-poles of the regular PM, the standard-Halbach PM and the multipole-Halbach PM for changeable geometrical parameters. The obtained results are of much use in understanding intrinsically the performance characteristics of the AFPM.
