| dc.description.abstract | 本論文建置預測技術系統主要是針對分散捲表貼式永磁同步馬達（Surface permanent magnet synchronous motor , SPMSM）的效率問題進行有限元素法求解。首先，針對高功率永磁馬達建置損耗預測系統，以電磁-電路之雙重物理耦合場解析為目標，運用有限元素軟體(Maxwell)對馬達的輸出扭矩進行求解，並求得輸入理想電流情況下，馬達的損耗大小，後續設計實驗平台，透過此平台進行馬達效率物理量直接量測，將模擬和實測數據進行一致性比較，建立損耗預測系統之可性度。在建立高可性度之高功率永磁馬達損耗預測系統之後，利用電路模擬軟體(Simplorer)模擬變頻器實際輸出電流，使用軟體的內建馬達進行求解，以研究電流漣波對馬達損耗的影響，並與理想輸入電流和實驗的損耗做比較，從而建立高可信度的模擬平台。此外，為了預測馬達產生共振頻率，使用ANSYS軟體分析馬達的自然頻率，並透過敲擊試驗法分析馬達的自然頻率，將實驗與模擬進行比對，作為未來預測馬達振動頻率的依據。 | zh_TW |
| dc.description.abstract | 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. | en_US |
