Axial flux electromagnetic differential induction motor
Seventh International Conference on Electrical Machines and Drives, 1995This paper presents an axial-flux induction motor which has a single stator and two squirrel-cage rotors mounted on individual, independents shafts driving two wheels of an electric vehicle. This novel induction machine inherently behaves as an electromagnetic differential motor and thereby performs the function of both the engine and the differential ...

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 ...

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 ...

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.

Design and Control of an Axial Flux Machine for a Wide Flux-Weakening Operation Region
2007 IEEE Industry Applications Annual Meeting, 2007This paper describes the strategy to design and control of an axial flux SPM machine for achieving a wide flux-weakening operating region. By using a slotted stator with fractional slot windings and additional cores enclosing end windings, the axial flux machine satisfies the specification of a wide constant power speed range.

Critical Heat Flux in Tubes With Cosine Axial Heat Flux
Heat Transfer: Volume 2, 2005In this study a method to predict CHF (Critical Heat Flux) in vertical round tubes with cosine heat flux distribution was examined. For this purpose a uniform correlation, based on local condition hypothesis, was developed from 9,366 CHF data points of uniform heat flux heaters.

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 ...

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 ...
