An Improved Design of Induction Motor for EV with Hairpin Winding

指導教授 : 鄭榮和

摘要


本研究以改良電動車感應馬達的效率、力矩漣波與功率密度為研究主軸。藉由Hairpin繞組設計增加佔槽率,進而減少馬達損失,並透過參數最佳化方法,達到性能提升之目的。 首先,對原型馬達進行實驗測試與模擬分析,藉由結果得到可以改良的目標。接下來,應用磁路分析軟體進行各參數探討,其中包含了解Hairpin設計對馬達造成的磁路影響,如渦流效應、磁飽和等,以及為了使Hairpin設計有更好的結果,針對定子槽型、定轉子槽數、氣隙大小等參數作改良影響的探討。之後導入最佳化軟體,並建立一套優化流程,對各參數進行最佳化分析,在符合限制條件下,得到最佳的參數匹配,達到磁路改良之目的。

The goal of this research is to improve the efficiency , torque ripple , and power density of induction motor for electric vehicle. By the design of Hairpin winding which is benefit for increasing slot fill factor and reducing the loss and through the parameter optimization method, to achieve the purpose of performance improvement. First, experimenting and analyzing the prototype to discover improvable targets. Next, applying electromagnetic field simulation software to access all the factors including eddy effect and magnetic saturation, the magnetic impact from Hairpin. Moreover, reforming factors like slot shape of stator , slot number of stator and rotor ,and air gap for better results. Then, applying optimization software to find the best condition that fulfills the limitations and expectations for the purpose of reforming magnetic circuit.
