This paper proposes a novel modular stator 6-pole tubular linear rotary switch reluctance machine (TLRSRM). The proposed structure employs circumferentially distributed H-shaped stator modules, with each module’s four poles wound with concentrated windings. The outer stator pole windings and outer rotor form a three-phase radial magnetic circuit driving rotational motion, while the inner stator pole windings and inner rotor constitute a single-phase transverse magnetic circuit driving linear motion. This paper elucidates the motor’s operating principle and electromagnetic design process. Based on the three-dimensional magnetic field distribution characteristics, finite element analysis (FEA) was employed for three-dimensional magnetic field calculations to obtain flux linkage and torque characteristics. Additionally, the electromagnetic coupling effects between rotational and linear motions were investigated for the conjugate rotary-linear magnetic circuit within the modular stator. Simulation results indicate minimal electromagnetic coupling effects in the proposed TLRSRM structure. This study provides a robust theoretical foundation and empirical data support for further optimization and practical application of this motor topology.
