Purpose: This paper presents a contemporary direction on the reduction of vibration and acoustic noise in Switched Reluctance Motor (SRM) using Soft Magnetic Composite (SMC) blank. Methods: Soft magnetic composite materials are composed of iron powder and resin. The particles are compacted, together with a lubricant and possibly a binder, at high pressure into a bulk material. Soft magnetic composite materials are characterized by three-dimensional isotropic ferromagnetic behaviour and very low eddy current loss. The competence of Soft Magnetic Composite (SMC) material in Switched Reluctance Motor (SRM) on vibration related issues has been investigated through Finite Element Analysis and experimentation. Results: To analyze the magnetic, vibration, and acoustic noise characteristics two motor configurations, viz., M19-SRM (M19- Switched Reluctance Motor) and SMC–SRM (Soft Magnetic Composite - Switched Reluctance Motor) are considered. Conclusion: The efficacy of SMC–SRM (Soft Magnetic Composite - Switched Reluctance Motor) prototype in vibration mitigation has been validated. [ABSTRACT FROM AUTHOR]
