چکیده
In this article, a novel five-phase fractional-slot concentrated winding (FSCW) with 20-slot/22-pole is presented. It benefits not only the advantages of conventional FSCW but also weak space harmonics magnetomotive force (MMF). The allows eliminating first sub-order harmonic. new layout topology obtained by combination stator shift technique in slots special coupling windings (star-pentagon), using function theory. high performances are validated finite element method (FEM). Compared to winding, factor and total harmonic distortion (THD) MMF improved 1.3% 2.2%, respectively. With same injection current density, average output torque increased 1% ripple decreased 60%. eddy losses permanent magnets (PMs) at rated speed (600 r/min) 2100 r/min 67% 56%,

Six Phase Permanent Magnet Machine with Fractional Slot Concentrated Winding
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...
متن کاملInvestigation on Slot–Pole Combinations of a PM Vernier Motor with Fractional-Slot Concentrated Winding Configurations
This paper presents a new method to find available slot–pole combination of a permanent magnet (PM) vernier motor with fractional-slot concentrated winding (FSCW) configurations instead of the conventional design rule. To this aim, for a common structure of PM vernier machines with FSCW, the air gap flux densities including modulation flux due to vernier effects are investigated from the magnet...

متن کاملCalculation on the Winding Factor and Armature Reaction MMF of a PMSM with 5-phase Fractional-slot Winding
In this paper, a permanent magnet synchronous machine with fractional-slot and 5-phase winding is studied. By superposing of the back EMF (electro-motive force) phasors of all coil-sides in a phase winding, the winding factor of the machine is calculated. The idea of this calculation method is a clear, and operation is easy and fast. In normal working, one-phase open-circuit fault, opencircuit ...
