dc.description.abstract自從馬達被發明出來,經過不斷的改良與創新,現在馬達在工業界已經是一種不可或缺的重要元件,舉凡辦公室裡面的產品,幾乎都可看到馬達的存在,像是印表機,光碟機,掃描器...等。因此,如何控制馬達便成為一個重要的學問。 在三相永磁馬達的磁路參數中有一感應電動勢常數Kemax(或稱扭矩常數)(在m.k.s制下感應電動勢常數Kemax等於扭矩常數Kt),關係到三相永磁馬達本身的性能、出力大小與可操作的工作轉速,所以不管是馬達設計者或是其使用者都非常在意它,若能事先量測,便可作為設計三相永磁馬達控制器或挑選三相永磁馬達的參考。 本論文利用一種新的方法,利用讓馬達在單相旋轉時候的特性,將感應電動勢常數快速的計算出來。本實驗透過ADDA卡以及驅動IC(BA6849)來驗證此方法的可行性,並將此方法實際應用到產品的開發上,希望能加速馬達廠在檢測感應電動勢常數的時間,進而將其檢測感應電動勢列為產品全部檢測的項目之一,以提高產品的品質。zh_TW
dc.description.abstractSince the motor is invented, through people's constant improvement and innovation, the motor becomes a kind of indispensable important component in the industry now. We can nearly all see the existence of the motor in the products inside all offices, it is like a printer, CD-ROM drive, scanner ,etc.. So, how to control the motor becomes an important knowledge. There is a reaction EMF constant (or called the torsion constant)(the EMF constant under the metric system is Equal to the torsion constant) in the magnetic parameter of the permanent-magnet synchronous motor. It relates to value of the torque, rotational speed that can be operated, and the performance of the motor. So motor designer or user all take notice of it very much . If we can estimate it in advance, can be as a reference of designing the motor controller or selecting the permanent-magnet synchronous motor. This thesis utilize one new method which is using the characteristic of the motor when let motor rotate in single-phase mode, to calculate the reaction EMF constant fast. This experiment use driver IC(BA6849 ) and an ADDA(Analog to Digital and Digital to Analog) card to verify the feasibility of this method, and apply this method to the products actually. Hope that can accelerate the time of motor factory's measuring the reaction EMF constant. And then motor factory can make the measuring reaction EMF constant to the list of all products should be measure . In order to improve the quality of the products.en_US
