Effect of Wire Size and Slot Filling Factor on the Number of Turns Per Pole in Design of SRM

As electric vehicles become increasingly important and widely used, the design of every type of electric motor has gained significant attention in both literature and industry. This study provides a detailed analysis of the number of turns in the motor windings, a critical factor in electric motor design. Through comparative analysis, it investigates how wire size and slot filling factor affect the number of windings turns per pole in Switched Reluctance Motors (SRMs). In addition, the study evaluates the effect of the number of turns analysis on motor performance during design optimization using the genetic algorithm tool in Ansys and traditional calculation methods. The optimization was performed with the wire size range between 0.45 and 0.85 mm. As a result, the optimal value with 82% efficiency was obtained with a wire size of 0.81 mm and 312 turns. The lower copper losses, ideal volume, reduced costs, and enhanced efficiency are obtained by determining the optimal number of turns. This research contributes to developing more efficient and cost-effective electric motor designs. Future research could explore various and more effective optimization techniques and current parameters to design SRM and other motors.
