Abstract: The present invention is a apparatus of multi-unit modular stackable switched reluctance motor system with parallely excited low reluctance circumferential magnetic flux loops for high torque density generation. For maximized benefits and advanced motor features, the present invention takes full combined advantages of both SRM architecture and “Axial Flux” architecture by applying “Axial Flux” architecture into SRM design without using any permanent magnet, by modularizing and stacking the “Axial Flux” SRM design for easy configuration and customization to satisfy various drive torque requirements and broad applications, and by incorporating an en energy recovery transformer for minimizing switching circuitry thus further lowering the cost and further increasing the reliability and robustness. Unlike prior arts, the present invention does not use any permanent magnet and this “Axial Flux” SRM system is modularized and stackable with many benefits.
