An Overview of Axial-Flux Induction Machine
2021 31st Australasian Universities Power Engineering Conference (AUPEC), 2021Electrical motors are one of the key building blocks in power systems and an important load type in industry and residential buildings. The concept of axial-flux induction machines (AFIM) is drawing particular attention since it shows performance characteristics that are superior to the conventional radial flux induction machine (RFIM).

A mathematical model of Axial Flux Disc Machines
2009 International Conference on Power Engineering, Energy and Electrical Drives, 2009This paper describes a mathematical model to determine the equivalent circuit parameters of Axial Flux Disc Machines (AFDMs) of whatever configuration. Once fixed the dimensions of the machine (magnet width, winding lengths, axial thickness, etc.), the equivalent inductance and resistance and finally the current are calculated, for a generator ...

2018 IEEE International Magnetics Conference (INTERMAG), 2018
Magnetic gears (MGs) have recently been proposed to replace conventional mechanical gears in various electromechanical systems. MGs have competitive torque transmission capability compared with their mechanical counterpart[1]. Moreover, by integrating an MG into a conventional PM machine, a magnetically geared machine has emerged, greatly broadening ...

Axially Stacked Multiphase Flux Reversal Machine
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019This paper introduces a novel three-phase flux reversal machine. Unlike conventional machines, the proposed machine is based on a multi-layered design with three magnetically independent rotors and stators on the same shaft. Each layer represents a single-phase flux reversal machine (FRM), which is mechanically shifted against each other.

Modeling of axial flux PM machines
IEEE International Electric Machines and Drives Conference, 2003. IEMDC'03., 2003In modeling axial field machines, 3D FEM models are required in accurate computations. However, 3D FEM analysis is generally too time consuming in industrial use. In order to evaluate the performance of the axial flux machine rapidly, an analytical design program that uses quasi-3D computation is developed.

Effects of manufacturing dissymmetry in axial flux PM machines
2012 XXth International Conference on Electrical Machines, 2012The paper discusses the effects that various kinds of manufacturing dissymmetry can cause in axial flux PM machines. A case study is considered, and, in particular, two effects are investigated: the circulation current in parallel paths at no load and the mechanical stresses together with the resulting axial force and bending torques on the machine ...

Thermal analysis of an Axial Flux Permanent Magnet machine
2012 XXth International Conference on Electrical Machines, 2012Analytical 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

Axial-Flux PM Machines With Variable Air Gap
IEEE Transactions on Industrial Electronics, 2014Laminated soft magnetic steel is very often used to manufacture the stator cores of axial-flux PM machines. However, as the magnetic flux typically has main components parallel to the lamination plane, different magnetic flux density levels may occur over the radial direction: High flux densities near the saturation level are found at the inner radius,

Axial-flux-machine with an ironless fractional slot winding
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014In this paper, a novel 42 slot, 20 pole ironless winding for use in an axial-flux machine is presented. The proposed design improves the utilization of the available air gap area and is based on the implementation of the winding as a printed circuit board (PCB).

AXIAL FLUX WHEEL MACHINES FOR ELECTRIC VEHICLES
Electric Machines & Power Systems, 1996ABSTRACT Several possible solutions for axial flux wheel motor drives for Electric Vehicles (EVs) are invesligated. As a case study, a small electric city car has been chosen and a 10 kW motor for each wheel has been selected for the comparison between the different motors types.
