Abstract
Abstract: The subject of this paper is to optimize the design of conventional claw pole alternator for automotive industry, especially at idle speed. Commonly, during idle speed, claw pole alternator isn’t able to sustain active electrical loads for a reasonable amount of time without excessive drain on the battery. Therefore, obtaining sufficient output power at idle speed is required. The optimization process aims to improve alternator output power, at idle speed, for given stator dimensions and footprint. To derive the optimal rotor structure, cyclic coordinate method linked with magnetic equivalent circuit (MEC) model is used, including magnetic saturation effect and leakage flux. Optimization results, which provide the optimized rotor geometrical dimensions, are discussed. Performances regarding the optimized claw pole alternator are evaluated over the entire operating speed range of the vehicle.
期刊介绍：
Advances in Systems Science and Applications (ASSA) is an international peer-reviewed open-source online academic journal. Its scope covers all major aspects of systems (and processes) analysis, modeling, simulation, and control, ranging from theoretical and methodological developments to a large variety of application areas. Survey articles and innovative results are also welcome. ASSA is aimed at the audience of scientists, engineers and researchers working in the framework of these problems. ASSA should be a platform on which researchers will be able to communicate and discuss both their specialized issues and interdisciplinary problems of systems analysis and its applications in science and industry, including data science, artificial intelligence, material science, manufacturing, transportation, power and energy, ecology, corporate management, public governance, finance, and many others.
