Title
Modeling and simulation of a rolling rotor switched reluctance motor
Abstract
The behavior of the rolling rotor switched reluctance motor (RRSRM) is strongly determined by the properties and mode of operation ofthe magnetic field [1]. The rotor is moved by the magnetic force in the stator, where this magnetic field depends on the varying air gap between the rotor and the stator. The aim ofthis work is the technical-mathematical description ofan RRSRM, the highlights of which describe the motor and the fundamental mode of operation. Thus, separate domains will be described, implemented and analyzed afterwards. These interdisciplinary effects influence the mode of operation and consequently the application of the RRSRM [2]. This multiphysical implementation and the simulation show many interconnections between the domains and the forthcoming works are affected by this technical expertise [3]. The design and the properties of the magnetic field determine the operation of the RRSRM and consequently the interactions between the electrical and mechanic al domains [2]. Therefore the magnetic field is described and implemented as a nonlinear network. The nonlinearity affects strongly the behavior of the rolling rotor switched reluctance motor. Furthermore, the operation of an RRSRM is determined by the coupling of the electric, magnetic and mechanic domains [3]. For these reasons a multi-physical description is implemented using MODELICA [4], so an interdisciplinary analysis of the RRSRM is made possible and this is the basis for future researches. Only with an exact technical-mathematical model it is possible to design new drive concepts [5].
