This paper discusses the suitability of four-phase, five-phase, and six-phase modular machines, for use in applications where servo characteristics and fault tolerance are key requirements. It is shown that an optimum slot number and pole number combination exists, for which excellent servo characteristics could be achieved, under healthy operating conditions, with minimum effects on the power ...

This paper presents a new three-layer, five-phase winding configuration theory of unconventional slot-pole combinations by each layer for phase vector correction, three layers superimposed together to achieve the results three-phase symmetry. Since single-layer has have an empty slot meet its symmetry, based on characteristics winding, design is carried out. Based simulation comparison between ...

This article investigates the effect of airgap length on electromagnetic performance direct-drive surface mounted permanent magnet Vernier (SPM-V) machines with different power ratings. Using 3 kW machine as an example, its is comprehensively compared a conventional SPM same lengths using two-dimensional finite-element analysis. For each length, slot/pole number combination for SPM-V inv...

A design package is developed for a single-tooth per stator pole switched reluctance motor, 6/4. The rather simple assumed flux path method is used to estimate the unaligned permeance including the leakage permeances and the effects of shallow slot and tooth taper. The possibility of making rotor tooth width greater than stator tooth width is examined using the developed package. The result app...

<span lang="EN-US">Linear permanent magnet synchronous motor (LPMSM) has emerged as a viable alternative to other linear motors for higher thrust lifting action. With the advancement of magnets, LPMSM could contribute energy conversation while also being suitable applications requiring thrust, such elevator. However, because existing is larger in size, it requires more space be equipped w...

This paper presents a two-dimensional analytical model for brushless double-rotor flux-switching permanent magnet machines (BDRPFSPMM) with yokeless stator recognized as type of partitioned-structure that is an appropriate machine to be employed the electric motor in industry. The most salient advantages proposed are low iron loss due volume and high space slot winding. radial tangential compon...

Permanent Magnet Machines (PMM) with a phase number (m) higher than three allow redundancy and lower torque ripple compared to their three phase counterparts. In this paper, a six phase permanent magnet machine with surface rotor magnets, designed with fractional slot tooth winding is proposed. A stator design with fractional slot tooth winding allows the design of a compact machine through sho...
