The paper present the analysis of the performances of an electrical machine used for small power automotive application. The electrical machine under study in this paper is a small flux synchronous reluctance machine (SynRM) with 4 poles and 24 slots. The analysis of studied machine will be carried out both analytically and numerically in SPEED program and Flux (2D and skewed solver).
Due to the advancement of electric vehicles, the desire for high torque density electric motors for traction applications is steadily increasing. It is advantageous to design such a motor with little or no rare earth permanent magnet (PM) material due to the associated environmental, political and economic challenges with its extraction and processing. This paper explores a novel synchronous reluctance...
The present paper deals with the comparative design and analysis of 3 Switched Reluctance Machine (SRM) topologies for electric vehicle propulsion. A preliminary design of the machine will be carried out, giving the initial geometric and electric (winding) data. Different numbers of phases and different combinations of stator and rotor pole numbers will be considered, keeping the same main dimensions...
This paper discusses a configuration of switched reluctance machine (SRM) that has novel relationship between the number of stator poles and rotor poles. Such a stator/rotor pole combination presents an SRM design with minimal torque ripple, acoustic noise and higher continuous rated power density. Further, the machine topology realizes these attributes while presenting attributes highly suitable...
This paper presents results from a design study on the feasibility of employing high-efficiency switched reluctance (SR) machines in minimal hybrid-electric vehicles. The application requirements are presented and highlight the constraining influences of the vehicle drive-line topology on the machine design. The benefit of continuous phase current excitation is reported for the first time, demonstrating...
This paper overviews various electrical machine technologies, including brushless permanent magnet, induction, switched reluctance, and brushless reluctance machines, with particular emphasis on the concept of hybrid electrical machine topologies, and compares their relative merits, in terms of torque and power density, operating speed range, over load capability, and efficiency, for application in...
This paper proposes a low-ripple instantaneous torque control method based on an adaptive torque sharing function for use with switched reluctance motor. The conventional torque sharing function technique is most effective when the SRM operates in low speed range and its performance deteriorates at higher speed. The proposed adaptive torque sharing function has the active period of each phase that...
Generic algorithm is used to optimize the turn-on angle and overlap angle and the torque ripple factor is selected as the fitness function. Four types of torque sharing functions for switched reluctance motor drives are evaluated by using the torque ripple factor. The investigation shows that the cubic torque sharing function is the prime choice in consideration of the minimum torque ripple, the simplicity...
For propulsion of electro and hybride vehicles basically 3 different motors are used: induction machine (IM), permanent synchronous machine (PM) or switched reluctance machine (SR). To analyse and compare these types of machines three electrically powered go-karts were buildt at Daimler Chrysler AG Stuttgart plant 10. These e-go-karts have the same configuration regarding batteries, power inverter,...
