A Comprehensive Review of Axial-Flux Permanent-Magnet Machines

Canadian Journal of Electrical and Computer Engineering, 2014
This paper presents a state-of-the-art review of axial-flux permanent-magnet (AFPM) machines in the aspects of construction, features, electromagnetic and thermal modeling, simulation, analysis, design, materials, and manufacturing. Some key references on the above-mentioned aspects pertaining to the machine are discussed briefly.

Rotor Losses Measurements in an Axial Flux Permanent Magnet Machine

IEEE Transactions on Energy Conversion, 2011
MMF space harmonics and slot openings produce considerable rotor losses in permanent magnet (PM) machines, especially if fractional-slot windings are adopted. This paper aims to measure the rotor losses of a 12-slot 10-pole axial flux phase modulation machine. Both MMF space harmonics and slot openings are considered.

Nonlinear Semianalytical Model for Axial Flux Permanent-Magnet Machine

IEEE Transactions on Industrial Electronics, 2022
This paper proposes a novel nonlinear semi-analytical model (AM) for the magnetic field calculation of electric machines. The nonlinear properties and local saturation effect of the iron part are taken into consideration in Cartesian coordinates, which is the main contribution of the proposed model. Thus, high accuracy of electro-magnetic field results

Thermal analysis of an Axial Flux Permanent Magnet machine

2012 XXth International Conference on Electrical Machines, 2012
Analytical lumped parameter circuits based on thermal resistances have been used extensively for calculation of the temperature rise in electrical machines. This work presents an analytical thermal equivalent circuit of an Axial Flux Permanent Magnet (AFPM) machine for steady state condition, used recursively with the electromagnetic design. From their

On the Use of Magnetic Wedges in Axial Flux Permanent Magnet Machines

IEEE Transactions on Industrial Electronics, 2013
Axial 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 acceptable constant power speed range.

A New Axial Flux Permanent Magnet Machine

IEEE Transactions on Magnetics, 2018
This paper presents a new axial flux permanent magnet machine, named ring winding axial flux machine (AFM). The ring winding AFM (RWAFM) takes the advantage of segmented stator of yokeless and segmented armature topology with those of decoupled phases and ring winding of transverse flux topology.
