Wing: Permanent Magnet Motor Technology, Design and Applications, Second edition, Marcel Dekker, 2002 Design and Analysis of a Fractional-Slot Concentrated-Wound ... con rmed in this investigation that this negative e ect for the 10-pole motor is ampli ed due to the presence of the concentrated winding. Indeed, it is shown by simulations that the motor performance is improved by employing 8 poles/12 slots PMaSynRM con guration with a relatively lower NdFeB magnet amount, thanks to the improved rotor anisotropy. Influence of the Coil Pitch and the Slot/Pole Number ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract- The aim of this paper is to find the best concentrated windings layouts for high pole number permanent-magnet (PM) machines. Pole and slot numbers are varied from 4 to 80 and 6 to 90 respectively. Among all the pole/slot combinations, those giving the highest winding factors are provided.
Unbalanced Magnetic Pull in Fractional-Slot Brushless PM Motors David G Dorrell, Mircea Popescu and Calum Cossar Dept of Electronics and Electrical Engineering University of Glasgow Glasgow, G12 8LT, UK Dan Ionel Corporate Technology Centre AO Smith Corp. Milwaukee 53224, WI, USA Abstract— This paper reports on an investigation into the Torque ripple reduction of synchronous reluctance machines ... Purpose – The purpose of this paper is to investigate the influence of stator and rotor pole number combinations together with the flux-barrier layers number on the performance of synchronous reluctance machine with emphasis on output torque capability and torque ripple. Vernier Motor with Fractional-Slot Concentrated Winding ... slots (or called the flux modulation pole), and winding pole pairs, respectively [1–4]. This rule can be readily applied to the distributed-winding machines, however, these windings generally employ lengthy end-turns with higher copper losses, and thus fractional-slot concentrated windings (FSCW) are preferred [5].
