The reduced weight due to the active parts makes reluctance machines a viable candidate for electro-mechanical applications. The critical choice in wind applications are on the capability of motoring and generative characteristics. Switched reluctance machines are viable candidate as with its extended constant power range operation replacing the conventional multi-gear transmission. Recently introduced...
A new toroidally wound switched reluctance machine (TSRM) with a single continuous multitapped winding is presented. This machine may be driven by a 6-switch asymmetric converter that supplies unipolar coil currents or by a 12-switch voltage source converter that supplies bipolar coil currents. The TSRM magnetic design and power electronic control is described, and its performance is compared with...
This paper is a synthesis of various research work performed on innovative structures for electrical machines responding to new performance requirements and applications. It will establish an initial comparison between the possibilities of both types of machines, namely the permanent magnet synchronous machine (PMSM) and switched reluctance machine (SRM), since more competing by conventional machines...
Due to the rotor position of switched reluctance motor (SRM) is a highly nonlinear function of stator windings current and flux linkage, so general linear and analytical methods are difficult to achieve precision results, in the paper, a method is presented that a genetic RBF neural network (RBFNN) is used to rotor position sensorless detection of SRM. Hence, extensive mapping ability of neural network...
Low cost, high reliability, low weight and competitive efficiency combine to make the switched reluctance motor (SRM) drive a strong candidate for application in future electric vehicle (EV) propulsion systems. In this paper , a three-phase 6/4 structure switched reluctance motor used in small size EV is proposed. Start performance and output property are both improved through optimizing the stator...
This paper presents the results of an investigation of torque development in the air gap of a 6/4 and 8/6 switched reluctance machines (SRM). Due to the force components acting on the rotor enables us to provide more accurate picture of the torque generation and vibration in this family of electric machines. The analysis for the torque is computed by finite element method. The torque optimisation...
