“…This paper presents an extensive review of the origin of torque ripple and the approaches used for the minimization of torque ripple considering various design and control methods. Later, in the year 2016, a novel cylindrical outer rotor shape was considered for reducing torque ripple in SRM by K. Kiyota, T. Kakishima, A. Chiba and M. A Rahman [9]. Torque ripple, acoustic noise and windage loss were seen to reduce at certain drive points only.…”

There is a growing interest in developing Switched Reluctance Motors for electrical traction applications. This is mainly due to the significant advantages as lower cost, better fault tolerance, high reliability possessed by Switched Reluctance Motor (SRM) when compared with any other rare earth motors. But the SRM suffers from a torque ripple problem due to its double saliency and this has limited its use in automotive traction applications. This paper deals with the design of an 8/6 20kW SRM used for electric vehicle application and comparison of performance of the conventional motor with that of geometrically optimized SRM. The conventional design method is available in literature. The optimized geometry is modeled using JMAG software and compared with the conventional one for reduced torque ripple. The optimization was done for the air gap, extended pole shoe, fillets and circular windows for reduced torque ripple. The simulation shows a reduced torque ripple for the optimized geometry.

“…Although some electrical machines without rare-earth PMs can achieve some excellent performance including high power density, high torque density and high efficiency, such as switch reluctance machines (SRMs) [4][5][6][7][8] and synchronous reluctance machines (SynRMs) [9][10][11][12]. Nonetheless, there are some problems, such as the vibration and acoustic noise in SRMs [13][14][15], and low power factor in SynRMs [16][17][18][19]. Moreover, rare-earth PMs can be partially replaced by low-cost ferrite magnets [20][21][22][23][24][25][26][27][28][29][30][31][32].…”

In this paper, a novel permanent magnet-assisted synchronous reluctance machine (PMASynRM) with rare-earth PMs and ferrite magnets is proposed. The performance of PMASynRM is discussed with respected to the different magnet ratio of rare-earth PMs and ferrite magnets. Some characteristics including the flux density, output torque, cogging torque, output power, power factor, torque ripple, loss, efficiency, and demagnetization are calculated by 2-D finite element analysis (FEA). The analysis results show that the excellent performance can be obtained by using hybrid magnet of rare-earth PMs and ferrite magnets with the suitable magnet ratio, and provide some desirable cost-performance trade-off.

“…However, the noise characteristics are one of the key performances of motors concerned by the users; 15,16 the switched reluctance motor (SRM) is generally considered as a large-noise motor due to its double-salient structure and nonlinear magnetic characteristic. [17][18][19][20] The improved motor design and effective control strategy can decrease the noise of SRM. The noise negatively affects the positioning accuracy of the PSRM.…”

This article presents the analysis of the noise characteristics for the planar switched reluctance motor to enrich performance evaluation of the planar switched reluctance motor. The mechanical structure, electromagnetic force, and control scheme are first presented. An analytical mathematical model of sound intensity is then proposed to characterize the relationship between the mechanical structure and the noise. An improved mechanical structure is further designed and analyzed to decrease the deformation by using ANSYS Workbench. Furthermore, an experimental setup of noise measurement is built based on the developed planar switched reluctance motor. In addition, the noise is measured experimentally under the open-loop and closed-loop motions after performing the experimental measurement of ambient noise. The experimental results demonstrate that the planar switched reluctance motor is capable of achieving low-noise motion.
