Acoustic noise reduction is a key focus in the development of switched reluctance motors (SRM), with the flattening of three-phase radial force sum being an effective method. Experimental verification has been done by optimizing current profiles. New current waveforms have been proposed to reduce acoustic noise in the 18/12 SRM without sacrificing efficiency, which is competitive with permanent magnet motors in hybrid electric vehicles in terms of power density, torque density, peak efficiency, and dimensions.
Acoustic noise reduction is one of the main topics of switched reluctance motor (SRM) developments. One of the effective methods is flattening three-phase radial force sum. This method is verified in experiments by optimizing the current profile. Novel current waveforms have been proposed recently for acoustic noise reduction without sacrificing the efficiency in the 18/12 SRM, which has competitive power density, torque density, peak efficiency, and outer dimensions compared with the permanent magnet motor employed in hybrid electric vehicles. In this article, electro-mechanical analysis and acoustic analysis are carried out to verify acoustic noise reduction in the 18/12 SRM. The relationship between radial force sum F-rsum, torque ripple T-rip, and acoustic noise is investigated. Experimental confirmation is also included.
