Acoustic Noise Reduction in an 8/6 Switched Reluctance Machine Using Structural Design

Today, switched reluctance motors (SRMs) represent a promising technology for the long-term sustainability of electrified transportation, mainly due to their simpler structure, lower production cost, and robust configuration compared other motor technologies. Notwithstanding, high acoustic noise torque ripple are two performance imperfections that have prevented widespread implementation SRMs. This paper presents different structural design techniques reduce an 8/6 SRM, while maintaining electromagnetic machine. For each technique, corresponding multiphysics FEA analysis motor’s is presented. The accuracy model confirmed experimentally using measurements obtained from four-phase SRM. Then, several been investigated on SRM represented in main categories: stator-housing modifications rotor modifications. best strategies then combined improve level its performance.
