The modeling and simulation of Switched Reluctance (SR) machine and drives is challenging for its dual pole salient structure and magnetic saturation. This paper presents the input data in form of experimentally obtained magnetization characteristics. This data was used for computer simulation based model of SR machine, "Selecting Best Interpolation Technique for Simulation Modeling of Switched...

Variable speed constant frequency generating systems are used in wind power, hydro power, aerospace and naval power generations to enhance efficiency and reduce friction. In these applications, an attractive candidate is the slip power recovery system comprising of doubly-excited induction machine or doubly-excited brushless reluctance machine and PWM inverters with dc link. In this paper, a fl...

Various electric machines can be the candidate for electric vehicles applications, including induction machines, permanent magnet synchronous machines, switched reluctance machines, etc. Another class of machine, which has been relatively ignored, is synchronous reluctance machines. In order to enhance and increase torque density of pure synchronous reluctance machines, the low cost permanent m...

Combining the main advantages of the permanent magnet synchronous motors and pure synchronous reluctance motors (SynRM), permanent magnet assisted synchronous reluctance motor (PMaSynRM) has been considered as a promising alternative to the conventional induction motors. In this paper, utilizing a macroscopic design parameter, called insulation ratio along the q-axis, and based on the magnetic ...

INTRODUCTION Recently, the study of single unit spherical actuators that can perform multi degree of freedom movements has increased. The spherical actuator is an electric machine that is able to tilt its shaft on multiple degrees of freedom using electromagnetic force. Various types of spherical motors have been developed. Lee et al.[1-4] devised variable reluctance spherical actuators. They r...

This paper is related to comparison of two switching techniques that can be applied to asymmetric bridge converter driven switched reluctance machine. Switched reluctance motor operation principles are discussed. Theoretical circuit operation description and Matlab simulation software are used for switching technique comparison. After analysis shows that modification of switching technique have...

A hollow cylinder flywheel rotor with a novel outer rotor switched reluctance machine (SRM) mounted on the interior rim is presented, with measurements, numerical analysis and analytical models. Practical experiences from the construction process are also discussed. The flywheel rotor does not have a shaft and spokes and is predicted to store 181 Wh/kg at ultimate tensile strength (UTS) accordi...

In the paper the main analytical models of the switched reluctance (SR) machine are presented, based on geometry data, magnetic equivalent circuits and finite element (FEM) analysis results. In each case a representative example is given and finally the advantages and the weak points of each type of model are evinced.
