Optimum geometry for torque ripple minimization of switched reluctance motors Sahin, F; Ertan, HB; Leblebicioğlu, Mehmet Kemal (Emerald, 1995-12-01) This paper briefly describes an approach to determine the optimum magnetic circuit parameters to minimize low speed torque ripple for switched reluctance (SR) motors. For prediction of the torque ripple, normalized data obtained from field solution and a neural network approach is used. Comparison of experimental results with computations illustrates the accuracy of the method. The optimization method is briefly described and some results are presented.
Optimum geometry for torque ripple minimization of switched reluctance motors Sahin, F; Ertan, Hulusi Bülent; Leblebicioğlu, Mehmet Kemal (2000-03-01) For switched reluctance motors, one of the major problems is torque ripple which causes increased undesirable acoustic noise and possibly speed ripple. This paper describes an approach to determine optimum magnetic circuit parameters to minimize low speed torque ripple for such motors. The prediction of torque ripple is based on a set of normalized permeance and force data obtained from numerical field solution for doubly-salient geometries. For that purpose a neural net is trained to extract the data neede...
Optimum pole combination to maxmize torque density in switched reluctance motors for electric vehicle applications Tarvirdilu Asl, Rasul; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2016) Nowadays, using Switched Reluctance Motors (SRM) as a substitute for Interior Permanent Magnet Synchronous Motors (IPMSMs) in hybrid electric vehicle applications is of great interest. The main advantage of using SRM is elimination of permanent magnet materials in machine structure. In addition, simple and robust structure, high rotational speeds and operation at higher temperatures are other benefits of using switched reluctance motors. In this study, a combined analytical and Finite Element (FE) based met...
Optimum current injection strategy for magnetic resonance electrical impedance tomography Altunel, Haluk; Eyüboğlu, Behçet Murat; Department of Electrical and Electronics Engineering (2008) In this thesis, optimum current injection strategy for Magnetic Resonance Electrical Impedance Tomography (MREIT) is studied. Distinguishability measure based on magnetic flux density is defined for MREIT. Limit of distinguishability is analytically derived for an infinitely long cylinder with concentric and eccentric inhomogeneities. When distinguishability limits of MREIT and Electrical Impedance Tomography (EIT) are compared, it is found that MREIT is capable of detecting smaller perturbations than EIT. ...
Optimum Profile Modifications for the Minimization of Dynamic Transmission Error ÖZTÜRK, VEYSEL YALIN; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2014-08-28) An optimization study is performed target being the reduction of dynamic transmission error (DTE) for a selected operational range, where the operating torque and speed ranges are defined. For this purpose, two different models, i.e. a single degree of freedom (SDOF) lumped gear dynamics model and a multi-degree of freedom (MDOF) lumped model of a gear pair which is combined with shaft and bearing dynamics are employed. The differences between the optimization results obtained through loaded static transmis...
