Calculation of Performance Characteristic of In-Wheel Asynchronous Motor for Electric Vehicle

Öz

The main purpose of this study is regarding to design an in-wheel motor for an electric vehicle. Besides, the geometric optimization study of designed asynchronous motor has been realized to achieve maximum performance. In this study, performance characteristics of asynchronous motors in different geometric dimensions were investigated using the ANSYS RMXprt program. Investigated performance characteristics relate to rated revolution and rated torque, starting torque, breakdown torque, power factor, efficiency and magnetic flux on rotor and stator. A new motor model with hybrid geometry has been proposed. By using experimental results from calculating motor performance, an interpolation graph was created.  A performance curve for this motor is fitted through the generated interpolation graph. The motor performance has been tried to investigate engine performance by this curve on interpolation graph. It is predicted that better results can be obtained a motor with hybrid geometry from obtained findings. Therefore, some analysis has been done to confirm the proposed model. This motor model with hybrid geometry has been shown to optimize the performance characteristics in a limited package on in-wheel motors. Future work for this motor with hybrid geometry has been planned to investigate performance characteristics on the 3D platform by using finite element method.
