Integration of an Induction Machine Synthesis in a Multiphysic Simulation Tool for Automotive Applications
Résumé
As a part of the powertrain system of vehicle, variable speed induction machines are subject to constrained conditions: high power density, wide speed range, temperature, saturation, low cost. Conventional design methods based on constant speed induction machines must evolve into systemic techniques to take into account all these specifications. This paper presents a simplified multiphysic design program called 'synthesis' dedicated to be integrated in a systemic hybrid vehicles simulation tool, VEHLIB, to study the influence of the flux weakening range on induction machine's size. The design synthesis program demonstrates that for an integrated structure, above 2.5 times the base speed, the flux weakening range affects the machine's length. Simulation analyses are compared with experimental data to substantiate the method.
