EVS 28 KINTEX , Korea , May 3-6 , 2015 Design of the End-Coil Structure with Square Conductor for the Automobile ISG

This paper presents the stator winding method necessary for the high torque density, high efficiency and size reduction of an electric motor. We uses a Finite Element Method (FEM) to comparatively analyze the changes of performance in vehicle-mounted induction motor type Integrated Starter Generator (ISG) when it uses circular and square conductor. In addition, by analysing air flow, this study uses Computational Fluid Dynamics (CFD) method to analyze cooling performance by form of end-coil. By these results, we have effort to find the optimum end-coil shape that can increase the efficiency of motor performance and
