Reduction of Torque Ripples in Multi-Stack Slotless Axial Flux Machine by Using Right Angled Trapezoidal Permanent Magnet

The aim of this paper is to design, analyze and optimize the “Multi-Stack Slotless Axial Flux Switching Permanent Magnet Machine”. In design process, mathematical models are implemented, Finite Element Method (FEM) performed machine performances. aims minimize occurrence cogging torque ripple in multi-stack slotless stator AFPM machine. As a consequence, it reduces vibrations increases its life span. Multi-stack with right-angled trapezoid-shaped PM proposed comparison done conventional shape order examine performance Analysis (FEA) used. To further enhance characteristics designed shape, optimization by considering inner outer pole pitch as variables. krigging method assigned Latin Hyper-cube Sampling genetic algorithm (GA) due suitability non-linear data. Then, finite element analysis JMAG-Designer verify results. It determined that optimized model has achieved 65% reduction ripples compared design. Hence, work attempts
