Description
Summary:Due to the advantages of flexible flux modulation ability and robust structure, substantial interest has arisen in utilizing the hybrid excited double salient machine (HEDSM) in electrical drive. As a type of flux modulation machine, there exist diverse harmonic components during the modulation process, which all contribute to the back-electromotive-force (EMF) and torque. In this paper, the mechanism of electromagnetic torque generation in HEDSM is fully analyzed and derived as a mathematical expression using the flux modulation theory. Moreover, many parameters like the excitation current, angle of the asymmetric stator pole, outer radius of rotor, the structural size of poles in both stator and rotor, etc. in the HEDSM are optimized to maximize output torque by analytical and FEA methods. Finally, a 12/7 HEDSM prototype is manufactured and the theoretical analysis in the paper are all validated.
