Abstract |
Recently, the government with focus on environmental pollution is making a policies to regulate the conventional vehicles with fossil fuel. With respect to various issues, the electric vehicles are being developed. However, the high cost of rare-earth permanent magnet and limited reliability are significant issues since most of motor types use three-phase and permanent magnet. This study proposes 6-phase permanent magnet assisted synchronous motor to overcome these disadvantages. Initial design of motor model was selected by lumped parameter model and optimized using differential evolution strategy. The designed motor was verified through finite element analysis and torque characteristics were analyzed in case of failure. And the motor was manufactured and its performances were evaluated. |
