This paper presents a novel topology of dual airgap radial flux permanent magnet vernier machine (PMVM) in order to obtain higher torque per volume and similar average compared conventional PMVM machine. The proposed contains two stators sandwiched yokeless rotor. rotor helps reduce the by providing an effective linkage stator windings. improved competitiveness was validated using 2D finite ele...

In this paper, a parameterized transient finite element model for permanent magnet (PM) dimension analysis and performance simulation of a V-shape interior permanent magnet synchronous motor (IPMSM) with 8 poles is developed. The relationships between induced electromotive force (EMF) and PM dimension, cogging torque and PM dimension are analyzed; the geometries of PM structure are optimized by...

This paper deals with two kinds of optimisation problems, relevant to the optimised source distribution and the shape optimum design, using Continuum Design Sensitivity Analysis (CDSA) in combination with standard electromagnetic (EM) software. Fast convergence and compatibility with existing EM software are the distinctive features of the proposed implementation. In order to verify the advanta...

In this study, a design method is proposed for forming notches on the rotor surface to reduce cogging torque of interior permanent magnet synchronous motors (IPMSMs) with double-layered magnets. The predominantly based theoretical equations and can be applied general IPMSMs, regardless arrangement. First, waveform square air-gap flux density (Bg2) reference model approximated using two-step tra...

Flux switching motor is a type of electric machine that locates both flux source and armature windings on the stator leaving its rotor a simple piece of iron. This machine was developed by combining the toothed stator structure of induction machine and the toothed rotor structure of switched reluctance machine together. Furthermore, it has three types of flux sources which include permanent mag...

Due to enormous advantages, BLDC motors have been identified for the design in various applications. With its good power density, this motor is being used by automobile industry. The paper aims battery electric vehicle. major challenge of reduce torque ripples which appear because high cogging torque. Torque ripple results acoustic noise and vibrations vehicle badly affects performance efficien...
