碩士 === 國立中央大學 === 機械工程學系 === 104 === This thesis studies how to establish a finite element approach to solve the efficiency problem for a SPMSM system. There are two parts of this thesis. The first part is using FEM software to predict the energy loss of the motor by using ANSYS Maxwell to obtain the torque under ideal current assumption. The second part is to build an experiment platform and compares the experiment result with that of the simulation. After the high confidence system is established, Simplorer software is applied to obtain the output current of the inverter and study the energy loss influenced by current ripple. The result of energy loss is compared with that of deal current simulation and experiment. In addition, in order to predict the vibration of a motor, ANSYS software and an impact test are applied to analyze the nature frequency respectively. The results are compared and can be used as the basis to predict the frequency of a motor.
