Abstract

The Permanent Magnet Synchronous motor is a rotating electric machine where the stator is a classic three phase stator like that of an induction motor and the rotor has surface-mounted permanent magnets. In this respect, the PMSM is equivalent to an induction motor where the air gap magnetic field is produced by a permanent magnet. The use of a permanent magnet to generate a substantial air gap magnetic flux makes it possible to design highly efficient PM motors. The application of high performance of permanent magnet synchronous motors (PMSM) is increasing. However the performence of PMSM are closely related to it structure parameter. PMSM models with accurate parameters are significant for precise control system designs. Acquisition of these parameters during motor operations is a challenging task due to the inherent nonlinearity of motor dynamics. This project of designing the PMSM is to achieved a few of goals that are to model the PMSM using Solidworks software. It also to have to optimum result or performance by adjusting the parameters which are be the manipulative value in this project. By using FEM technique, this model of PMSM been simulated and FEM been chosen because it can have the complete model to analyze and also can give better result rather than PAM. The generated stator flux together with the rotor flux, which is generated by a rotor magnet, defines the torque, and thus speed, of the motor. Overall the results were achieved as what had been estimated before the project. The best performnance and optimization result had been analyzed using the graph and chart. The method used in this project was absolutely right and the simulation goes smoothly. Magnetic analysis that are the magnetic flux path, magnetic flux density and also meshing been analyze correctly and shows that the simulation gave a good result that will give best result for torque and cogging performance.
