A switched reluctance machine for high-torque low-speed applications

This paper presents a first overview of an unconventional switched-reluctance rotating machine conceived to provide high specific torque in low-speed applications by leveraging on the magnetic gearing effect while featuring a simple, modular, highly symmetrical structure that should permit to limit manufacturing costs. After recalling the main proposals found in the literature for similar targets, the first application considered for the machine is briefly described. The proposed structure is then introduced and briefly analyzed, highlighting the main features and issues related to manufacturing, performance and control. A few results coming from 3-D FEM analysis of the machine are finally reported and briefly commented
