English Abstract

Energy consumption and air pollution are the issues which been discussed in recent years, the development of electric vehicles is regarded as the key to solve this problem, but to coMPare with traditional motor, the elect motor need more power and lower volume and to meet these requirements the problem "heat dissipation" show up. The purposes of this research are to establish a permanent magnet motor thermal model and an improvement for the cooling system. In the research will use the computational fluid dynamic(CFD) instead of heat resistance of the physical modeling due to numerous internal components and itself complex geometry of permanent magnet motors. The CFD is to discrete the model to several regions and these regions are mold by elements and nodes then to use the appropriate algorithm for the result. This research of the motor thermal model especially regard to the reflection of the heat transfer in motor's air-gap and the contact heat resistance between stator and shell then insert the result to the motor thermal model. The result of flowfield analysis found that it’s not easy to do the heat dissipation on original motor due to the fin type and it got better outcome when change to flat fin type which experiment via Taguchi experiment method. By this way it can substantially decreases the temperature.
