This article presents a novel flux-switching (FS) machine adopting star-array permanent-magnets (PMs), termed as star-FSPM machine. In comparison with the conventional spoke-FSPM machine, proposed one can achieve not only enhanced flux-concentration effect, but also enlarged stator-slot area, thus improving PM utilization ratio and torque density. The harmonic characteristics of both field arma...

Abstract The article introduces the results of studying magnetic field distribution in alternator inductor with an axial arrangement open cores (OMC) and external closure fluxes. study compares efficiency using fluxes from permanent magnets (PM) on example two model variants inductors OMC developed by authors. analysis density was carried out 3D modelling EMWorks software. It has been shown tha...

Fuzzy logic is recently getting increasing emphasis in soft computing applications in the recent days. This paper presents an application of the fuzzy logic scheme to control the speed of an AC servo system & the same is proposed for a space vector pulse width modulation (SVPWM) inverter-fed permanent magnet synchronous motor (PMSM) drive. Based on the analysis of the PMSM transient response, a...

Permanent magnet arrays have advantages for magnetic field generation over the traditional current based magnetic flux sources, such as electromagnets, in that they do not require a power supply and cooling system. Magnetic flux density above the magnetic remanence BR of the permanent magnet material can be achieved by arranging the permanent magnet segments in the form of hollow cylindrical sh...
