dc.description.abstract | BLDC 전동기는 구동이 간단하고, 소형으로 제작 및 사용이 가능하여 양산성이 우수하다. 그리고, 선형적인 출력특성으로 인해 제어성 또한 우수하다. 그렇기에 전력변환장치의 보급화로 인한 교류 전동기 산업이 활발한 오늘날에도 여전히 다양한 분야에서 BLDC 전동기가 사용되고 있다. 본 논문에서는 다양한 어플리케이션 중 유도로켓의 날개 제어용 전동기의 개발을 수행하면서 연구를 진행하였다. 이 어플리케이션에서는 유도로켓에 장착되는 만큼 소형일 필요가 있으며, 제어성 또한 우수해야 한다. 그리고 다량 생산을 해야 하기 때문에 양산성이 우수한 BLDC 전동기를 선정하게 되었다. 먼저 슬롯형 BLDC 전동기를 설계를 하였으나 제작하는데 있어서 몇 가지 문제점이 있었다. 이에 문제점을 보완하기 위해 기존 모델인 슬롯형을 대체할 수 있는 슬롯리스형 BLDC 전동기의 설계를 수행하였다. 본 논문에서는 기존 모델인 슬롯형 BLDC 전동기를 대체할 수 있는 슬롯리스형 BLDC 전동기를 설계하는데 있어서 필요한 기초설계 프로세스를 제시하였다. 전동기의 상저항과 역기전력을 변수로 설정하여 기존모델의 동등 이상 출력 특성을 내는 제안모델을 설계하였고, 그 특성을 비교하였다. 그 결과, 고정자 치가 없는 관계로 철손이 줄었다. 이는 본 어플리케이션의 운전 포인트인 고속으로 갈수록 효율이 좋아졌다. 또한 기존 모델 대비 단순한 고정자 형상으로 인해 고정자 제작의 자동화에 용이해졌고, 권선을 감는데 있어서 권선기를 통한 작업이 가능하여 제작성 향상을 가져왔다. 가격적인 면에서는 전동기의 구조가 단순해짐에 따라 생산공정의 간소화가 가능해졌고, 스타결선을 사용함으로써 고정자 저항을 줄여서 고정자 권선 직경을 키우는 방향으로 설계할 수 있었다. 이는 가격 저감을 가져오게 되었다. 결론적으로 본 어플리케이션과 이와 유사한 경우에는 슬롯형 BLDC 전동기에 비해 슬롯리스형 BLDC 전동기가 더욱 적합한 것으로 보인다.|A BLDC motors are easy to drive. Also, small productions and operations are possible. It means BLDC motors are good at mass production. And the controllability is excellent, because of the linear output characteristics. Therefore, although AC motor industry is active due to the sufficient supply of electric power conversion devices in these days, BLDC motors are still being used in various fields. In this thesis, the study was made while performing motor development for the control wings of the guided missile from a wide range of applications. In this application, there is necessarily small enough to be mounted on the guided missile, and it should be excellent controllability. Also, in this case, because it requires a large amount of production, excellent mass productivity, the BLDC motor was selected. At first, a slot type BLDC motor was designed. But there are several significant problems in manufacture. To compensate for the problems, design of a slotless type BLDC motor was performed to replace the slot type BLDC motor, original model. In this thesis, Based design process of designing slotless type BLDC motor to replace the original model, slot type BLDC motor was presented. By setting the phase resistance and back electromotive force(back EMF, BEMF), the proposed model was designed for output characteristics at least equivalent than the characteristics of original model and their characteristics were compared. As a result, the iron loss of proposed model, slotless type BLDC motor was greatly reduced because there are no stator teeth. So, as operating at high speed, operating point in this application, the efficiency has improved. Furthermore, the automation can become easier in the manufacture of stator because of simple shape of stator in proposed model than that in original model. And manufacture ability can be improved since the winding machines can be utilized to wind the coils. In view of the production cost, as the structure of the motor becomes simple, the production process can becomes simpler. And as the use of stator coil winding with star-connection, the stator resistance reduced. So it can be designed in a direction to increase the stator winding diameter. This point was to bring a cost reduction. In conclusion, in this case or in a similar case, the slotless type BLDC motor can be more suitable than slot type BLDC motor.; A BLDC motors are easy to drive.
