Abstract: • Five phase non-overlapped wound field flux switching (WFFS) machines are analyzed. • The analyzed machines combine benefits of multi-phases and non-overlapped windings. • An evolutionary optimization method is executed to optimize WFFS machine models. • Optimized WFFS machine models achieve significant performance enhancement. • The WFFS machine prototype is fabricated to validate the results. The multi-phase machines are gaining significant interest in the field due to their high torque density and flexible working modes. Furthermore, non-overlapped winding topology offers many advantages such as reduced copper losses, less copper consumption and reduced machine cost. Five phase wound field flux switching (WFFS) machines combine the benefits of multi-phase machines and the advantageous features offered by the non-overlapped WFFS machines. Therefore, in this paper, five phase non-overlapped WFFS machines with various number of rotor poles are analyzed, optimized, and fabricated. Performance of the multi-phase WFFS machines from the aspects of flux distribution, back EMF, inductance calculations, DC induced voltage, torque characteristics, power and efficiency, are investigated and compared. An evolutionary optimization process based on the genetic algorithm (GA) integrated with the JMAG software is executed to optimize the machine models, resulting in significant improvements in the analyzed WFFS machine models. Finally, a prototype of the optimized design is fabricated to validate finite element (FE) results and overall, a good agreement between the measured and simulated results is achieved.
