Cover Story: This paper investigates segmented stator and rotor designs in AC electric machines, providing a comprehensive analysis of their potential benefits, challenges, and practical implications. It examines various manufacturing techniques, outlining their advantages, limitations, and influence on production efficiency and machine performance. The study further evaluates the impact of parasitic gaps on electromagnetic behavior and delves into the effects of additional cut edges on core loss, emphasizing their incorporation into finite element analysis (FEA) modeling. Additionally, it explores numerical modeling of segmented stators constructed using oriented steel, offering insights for enhancing future designs. View this paper
