A Transverse Flux Single-Phase Tubular Switched Reluctance Linear Launcher With Two Stator Poles

A tubular switched reluctance linear motor (TSRLM) for electromagnetic ejection with two stator poles and an interlaced structure is introduced in this article. The structure and operating principle of TSRLM are demonstrated in detail. Electromagnetic analysis of TSRLM is performed with the help of the 3-D finite element method (FEM). For optimal performance with the largest electromagnetic thrust, sensitivity analyses of the TSRLM on different parameters are carried out via 3-D FEM, such as stator yoke thickness, mover cylinder’s thickness, stator pole width, and stator ferromagnetic ring width, and the results of the sensitivity analyses are presented. The electromagnetic characteristics of the optimized motor are analyzed. The superior performance of the proposed TSRLM compared with its counterpart is verified by static 3-D FEM analysis and simulation of the dynamic model in MATLAB/Simulink.
