In mobile applications such as eletric vehicles, weight and installation space are the primary limiting factors that affect system efficiency consequently driving range. Reusing machine windings of an electrical inductors, e. g. in DC-DC converters for onboard chargers, saves space. However, currents when operating converter can result undesired torque ripple generated by machine. Therefore, st...

The present article proposes an effective model of synchronous reluctance machines. This model, called the Residual Magnetism (ReMa) takes into account not only residual magnetism within rotor but also that stator. Electromotive forces generated by ReMa were composed two frequencies and exhibited similar shapes as those measured in experiments. Resultant equations a three-phase <inline-formula ...

The reluctance synchronous motor (RSM) is a machine working on the basis of development of reluctance torque development. The rotor configuration with the salient poles is made from the rotor of asynchronous motor if some rotor teeth are symmetrically removed (mill out). A different air gap in d and q axis enables development of a reluctance torque. The rotor cage is asymmetrical because some b...

Nelson, Andrew Lincoln: Characterization of Winding Faults in Axial Flux Reluctance Motors in the Context of Electric Vehicle Propulsion Systems. (Under the direction of Dr. Mo-Yuen Chow.) Since the late 1980’s there has been a major resurgence in electric vehicle propulsion research and development. This trend has been stimulated by various factors, including rising fossil fuel costs, environm...

This paper presents the idea of manufacturing and fabricating a controller for four phase, 8/6 poles switched reluctance motor (SRM). The experimental results drawn from this controller are showing that the efficiency is a function of the applied voltage to the stator winding due to load variation, and found the best applied voltage that produced a better efficiency by this system is 85 VDC. Th...

Abstract—The switched reluctance machine (SRM) has undeniable qualities in terms of low cost and mechanical robustness. However, its highly nonlinear character and its uncertain parameters justify the development of complicated controls. In this paper, authors present the design of a robust H-infinity current controller for an 8/6 SRM with taking into account the nonlinearity of the SRM and wit...
