Abstract
This paper concerns the electromagnetic design of a hybrid-excited permanent magnet synchronous motor for use in traction automotive and transport applications. Initial topology and dimensions are chosen based on state-of-the-art electric motors used in existing electric vehicles today and taking into account the manufacturing possibilities at the university. The topology is then analyzed using 2D finite element method with respect to torque ripple minimization. Results of the optimization for varying topology parameters and DC current supply are presented, with corresponding magnetic field distributions, produced torques, etc. The optimization excludes mechanical and thermal analyses, which will be subject of future investigation.
