Integrated Simulation Toolkit for Electronic Controlled Motor System

ABSTRACT: The purpose of this study is to establish an analytical-numerical hybrid technique for system-wide thermal modeling of electronic controlled motors. The thermal models are fully coupled with electronic network model, which makes the simulation more close to real working conditions. It employs finite volume concept to handle heat conduction in solid media and adopts analytical equations to calculate velocity and temperature profiles for convection of fluid flow. The experimental data from various tested motors showed that a good accuracy could be reached by using much less time and effort compared to the numerical simulation, such as FVM or FEA. Simplicity, ease-of-use, coupled with electronic signal models, and moderate accuracy make this research attractive in solving complicated electrical-thermal systems. The model can be used not only for rapid thermal evaluation in early design stage, but also for detailed system-physical simulation.
