Axial flux segmental rotor flux-switching synchronous motor
2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015A novel three-phase, concentrated winding, axial flux, segmental rotor, flux-switching synchronous motor is presented. The proposed topology has rotor segments made of only iron laminations and operates with flux-switching principle. Compared to existing axial flux permanent magnet (AFPM) topologies, the proposed machine contains reduced amount of ...

An Axial-Flux Hybrid Excitation Flux-Switching Machine
Advanced Materials Research, 2011A flux switching permanent magnet (FSPM) machine has the advantage of high power density, high torque density, inherently sinusoidal back EMF, stable structure, and the disadvantage of magnetic field uncontrollable. This paper proposes a novel axial-flux hybrid excitation flux-switching (AFHEFS) motor, which offers three phase symmetrical sinusoidal ...

New Single-Phase Flux Switching Axial Flux Permanent Magnet Motor
IEEE Transactions on Magnetics, 2017In this paper, a new topology of a single-phase flux switching permanent magnet motor (FSPM) is presented. Unlike conventional FSPMs, the air-gap flux flows in the axial direction, and therefore, it is named the flux switching axial flux permanent magnet motor (FS AFPM).

Axial Flux Cycloidal Magnetic Gears
IEEE Transactions on Magnetics, 2014The radial flux cycloid permanent magnet gear is characterized by a high gear ratio and a high torque density due to the use of one air gap. There are at least three disadvantages of this gear: 1) eccentric motion of the output rotor must be transferred to concentric shaft rotation; 2) the bearing loads are very large due to the offset rotor rotation ...

A Comparative Study of Axial-Flux versus Radial-Flux Induction Machines
2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2020This paper presents the design process, detailed analysis, and a comparative study on the advantages of axial-flux induction machines (AFIM). A radial-flux induction machine (RFIM) is also studied as benchmark motor. Both motors are designed with six poles, 36 stator slots, and 32 rotor bars.

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 ...

Axial-Flux Induction Motors for Electric Vehicles
2019 IEEE Vehicle Power and Propulsion Conference (VPPC), 2019This paper presents design optimization of axial- flux induction motors (AFIMs) for electric vehicles. The approach is based on an analytical resolution of the Maxwell’s equations inside a set of subdomains. The analytical method is verified against 2D finite-element analysis.

Analytical Design of Axial-Flux Induction Motors
2019 IEEE Vehicle Power and Propulsion Conference (VPPC), 2019In this paper, two-dimensional (2D) analytical model is proposed for axial-flux induction motor (AFIMs) based on the solution of magnetic vector potential equations, which also considers the saturation’s effect on the performance of the machine. The model is developed from the quasi- magneto-static Maxwell’s equations, which are analytically solved.

Flux concentrating axial ferrite magnet motor
2015 IEEE International Electric Machines & Drives Conference (IEMDC), 2015Two stator axial motors are studied over different magnetization methods. As the rotor magnets, a high energy product ferrite (NMF-12G) is used. It has a 20 pole, 24 slot structure, and concentrated pole windings. Each piece of tooth is made by stacking three different size of sheets, and can be assembled into the pan cake type back iron disk. The back
