N2 - In high-precision and advanced applications, cogging torque poses significant challenges to machine systems. With a clear goal of extremely low cogging torque, this paper introduces a chiral modular stator (CMS) for permanent magnet machines (PMMs), featuring a mirror-symmetrical configuration analogous to chiral handedness. Through optimized module arrangement, the CMS induces phase-shifted slot reluctance variations, achieving effective cogging torque suppression (21.7 mNm, ≈0.1% rated torque). The modular design concurrently streamlines manufacturing processes and lowers production costs while maintaining torque density. Analytical analysis, simulation, and experimental verification confirm the CMS PMM's advantages, establishing it as a promising solution for precision PMM drive systems.
