An Investigation into the Effect of Non-segmented Rotor on the Torque of an Outer Rotor Switched Reluctance Motor for In-wheel Electric Vehicle Application
Abstract
High torque electric machines have been found in numerous applications in the industry including electric vehicle applications. It is not possible to achieve a considerable increase in the torque-producing capability of the machine by common optimization of the structure of electric machines. Hence, appropriate solutions for increasing the machine torque should be searched by proposing a different structure and focusing on the exact analysis of the machine forces. Deep knowledge of the electromechanical energy conversion process and the distribution of the force’s components will allow designing and developing a high torque density electric machine. Accordingly, in this paper, a double-stator switched reluctance motor is analyzed, firstly. Subsequently, based on the analysis, a high torque switched reluctance machine titled “outer rotor switched reluctance machine” for the in-wheel electric vehicle is designed. Finally, the effect of the non-segmented rotor is examined. Simulation is performed by the finite element method (FEM) in the MAGNET software.
