Modélisation, optimisation en vue du dimensionnement d’une nouvelle structure de démarreurs à griffes pour les véhicules « micro-hybrides »

Abstract : This thesis deals with a new DC machine structure that can be used in an automotive Stop-Start starter application. A three-dimensional claw pole stator is proposed to replace the current stator in order to reduce its manufacturing cost. The claw pole machine topology is modeled by a reluctance network to take into account the saturation and the magnetic armature reaction. Thanks to its speed and precision, this model is then integrated in an optimization process to obtain an optimal machine. Finally, a prototype of a machine with DC claws is manufactured to show the feasibility of this topology. Moreover, an original model combining reluctance networks and solving the Laplace equation has been developed to overtake some difficulties related to modeling by reluctance network of electrical machines while taking into account the rotation
