Torque performance, especially torque density, is a critical performance index for the flux-switching permanent magnet (FSPM) machine that attractive propulsion system. In this article, novel FSPM with dual sets of arrangements proposed. With topology, density proposed significantly improved due to much increased working harmonic contents magnetomotive force (MMF). Moreover, cogging also inhere...

In this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3D finite element modeling and experimental tests. The structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

Static eccentricity (SE) is frequently generated by manufacturing processes. As the nonuniformity of air-gap length caused SE, torque ripple and cogging increase in motor. This study analyzes distorted back electromotive force (EMF) due to SE. Further, a motor design considering SE performed for stable EMF low torque. First, was diagnosed analyzed using measured from test results base model. In...

This paper proposes a new type of dual-armature alternating pole bearingless magnetic flux reverse permanent magnet machine, which combines the advantages structure and structure. machine shows high torque density good fault tolerance, can not only reduce number magnets but also further improve machine’s torque. It is suitable for use in wind power, aerospace, other applications. The used to pe...

In order to study the operation process of motor and improve operating performance motor, this paper performs finite element simulation three-phase asynchronous optimizes initial design by using Taguchi method. Firstly, a model is established with voltage, current, torque, flux linkage, distribution lines magnetic induction intensity under rated conditions vertified Finite Element Analysis (FEA...

Abstract The permanent magnet motor will inevitably produce cogging torque because of its inherent structure, which cause vibration and noise affect application in certain high-precision applications. Firstly, considering the actual structure stator, a general analytical model is obtained by energy-based approaches. On basis further derivation expressions with different segmented pole structure...
