Performance Improvement of Axial Flux Permanent Magnet Machine with Phase Group Concentrated Coil Winding

This paper suggests a method to improve the performances of Dual Stator Axial Flux Spoke-type Permanent Magnet (DSAFSPM) machines with phase group concentrated coil (PGCC) windings, by incorporating continuous and discrete step-skewing along special winding connection. The purpose study is mitigate cogging torque ripples while increasing output so it ameliorates machine performance at minimum cost for various applications such as wind power plants electric vehicles (EVs). Cogging produces noise vibrations which degrade machine’s reduces its life span. proposed sequence enhances improving distribution factor use skew step-skew magnets. research work improved help techniques increased sequence. Further harmonics are also mitigated overall volume kept constant magnet size design parameters fair analysis. Comparative analysis these performed using three-dimensional (3-D) time-stepped finite element (FEA). Proposed model I II reduce 42% 23%, respectively. By magnets, reduced up 81.5% 75%, reduction in vibration assists perform smooth operation. 60.8% that 59.3%.
