Comprehensive Report on Design and Development of a 100 KW DSSRM


Switched reluctance machines are low cost and fault tolerant alternatives for traction applications. Due to their relatively low torque density and high torque ripple, these machines have not been used in commercialized electrified power trains yet. The double stator magnetic configuration, where a segmental rotor shared between two stators, is proven to have superior torque density, lower acoustic noise and torque pulsation. The double Stator Switched Reluctance Machine (DSSRM) has a high potential of being the next generation of traction motors since it combines the advantages of permanent magnet free machines, such as low cost and independence from supply chain issues associated with rare metals, while providing high torque and power densities. This paper introduces the complete design process of a 100 kW DSSRM including electromagnetic, structural, thermal, and system level design. The performance of the developed DSSRM is verified with experimental data. This article presents overall study of DSSRM and describe merits of DSSRM drive system.
