No-Load Performance of Axial Flux Permanent Magnet Machines Mounting Magnetic Wedges
IEEE Transactions on Industrial Electronics, 2012Axial flux permanent magnet (AFPM) machines are being increasingly used in a variety of industrial, direct drive applications which benefit from their extreme axial compactness. In particular, slotted AFPM machines are of great interest, since they allow to achieve high torque densities together with an adequate constant power speed range.

Application of flux reversal principle for axial flux permanent magnet machines
Journal of Applied Physics, 2008Applications of flux reversal machine can be found both for linear and radial flux machines. For axial flux machines, only one application is reported considering a two phase machine. In general, flux reversal effect can produce higher back electromotive forces than other topologies for the less amount of permanent magnets and thus can increase the ...

Loss study of a novel axial flux permanent magnet machine
2011 IEEE International Electric Machines & Drives Conference (IEMDC), 2011This paper presents the loss analysis of a novel axial flux permanent magnet machine for flywheel energy storage system. Losses in iron-core and permanent magnets caused by both space harmonics and time harmonics are respectively analyzed using three-dimensional finite element method. Effect of skew of magnets on machine losses is also taken into study.

Modeling and permanent-magnet shape optimization of an axial-flux machine
2012 XXth International Conference on Electrical Machines, 2012This paper proposes a modeling method for axial-flux permanent-magnet machine (AFPMM) based on a finite elements analysis, and achieves a shape optimization of AFPMM poles. To solve the questions regarding the modeling of AFPMM with surface-mounted PMs, an axial 3-D to radial 2-D finite-element transformation is proposed.

Computations on heat transfer in axial flux permanent magnet machines
2008 18th International Conference on Electrical Machines, 2008Effective cooling is of paramount importance for axial flux permanent magnet (AFPM) machines due to their high power density. This paper presents a computational investigation on the effect of variation in some geometric parameters, (running clearance, rotor groove depth and rotational speed), on the cooling effectiveness of an AFPM machine.

Sensitivity analysis of YASA axial flux permanent magnet machines
2024 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)This paper reports the sensitivity analysis of a Yokeless And Segmented Armature (YASA) axial flux permanent magnet machine. The structure of the device facilitates its stator construction and assembly but leads to some design aspects that can affect the device's performance. The sensitivity of a YASA machine to these aspects is investigated, analyzing

Analytical analysis of axial flux Halbach permanent-magnet machine
2015 IEEE Magnetics Conference (INTERMAG), 2015This paper presents a three-dimensional (3-D) analytical magnetic field analysis of an air-cored axial flux Halbach permanent-magnet machine (AFPMM with Halbach). The 3-D analytical magnetic distribution is established using the magnetic scalar potential and modified BESSEL functions in the cylindrical coordinate system.
