姜萬元 大田工業專門大學 1983 論文集 Vol.32 No.-
A new method as described in which the D. C motor may regenerate power effectively to D. C supply. The principle is similar to that with a do chopper for regeneration of the power from do motor to do supply. In this method, how ever, thyrister switches synchronizing to the ac supply are used insted of a do chopper. The principle and the power calculations as well as experimental results are presented . From theoretical and experimental considerations it is clarified that there exist suitable trigger angle in the thyrister of the synchronizing switches.

Constant starting torque of a Wound rotor Motor can be achieved by inserting a fixed external element consisting of resistances and reactances Combination in the rotor circuit instead of using a saturable reactor or other feedback devices. This approach provides the desired starting characteristic at the low cost of starting equipment. The generalized equation for determining the values of external parameters for a desired starting torque are based upon a graphical approach.

본 연구는 전동기의 효율을 개선하기 위해 손실을 감소하는 방법을 다루었다. 전동기의 부정확한 명세서와 그 응용은 손실의 원인이 되며, 기동전류, 순환전류, 조립 정도, 자속밀도, 슬립의 크기, 슬롯의 개방정도, 공극의 크기,실리콘의 함량, 강판의 두께, 고조파, 생산과정의 질, 전류의 균등화, 성형코일, 영구자석, 구조물 등을 적당히 설계하므로서 줄일 수 있다. This paper covers the methods of reducing losses for improving the efficiency of motors. Incorrect statement of motor and the application can be cause of loss, which can be reduce by proper design of starling current, circulating current, order of constructing, the density of magnetic flux, the value of slip, order of open of slot, size of air gap, the value of silicon, thickness of sheet steel, high order frequency, quality of process of manufacture. equalizing of current, formed coil permanent magnet, structure and so on.

새로운 회전자 권선에 의한 권선형 유도전동기의 기동특성
강만원 大田産業大學校 1999 한밭대학교 논문집 Vol.16 No.1
This paper covers starting characteristics and design of a wound rotor induction motor call used to a double excited induction motor. They are employing in many electrical equipment systems of industrial field. The stator is same as that of the conventional induction motor. But the rotor was rewind with new style, as a result both of starting torque and operating efficiency could be high. But starting current could be small. The same result as that of a conventional induction motor with the external resistance on the rotor could be obtain. The structure could be simple, system cost could be low and the maintanence free, because of no slip rings, no brushes and no external resistance.

이 논문은 동기전동기의 해석과 설계를 다루었으며 고정자는 3상 유도전동기의 고정자와 동일하고 회전자는 철극형의 회전계자형이며 인버터는 직접 전원에 접속되었다. 에너지 변환을 담당할 고정자는 전류의 주파수를 제어 할 수 있는 인버터에 접속되었으며 동기모드에서 속도는 인버터 출력전류의 주파수를 가변하므로서 제어될 수 있다. This paper covers analysis and design of a synchronous motor, The stator is equal to that of three phase induction motor, and It’s rotor is rotating field type of salient pole. The inverter is connected to the grid, the stator to take care of energy convertion is connected to the inverter controllable frequency of current. The speed of synchronous mode can be controlled by varying the frequency of the Inverter output current.

이 논문은 직류기의 해석과 설계를 다루었으며 전기 에너지를 기계 에너지로 변환하는 장치를 전동기라 하고 기계 에너지를 전기 에너지로 변환하는 장치는 발전기라 하며 서로 가역적이다. 자장내에서 도채가 운동하면 그 도채에 기전력이 생기고 전류가 흐를수 있게되며 자장내에서 도채에 전류를 흘al면 그 도채에 전자력이 생기고 이 전자력에 의해 전동기는 회전하게 된다. 계자전류나 전기자 저항 및 단자 전압을 가감 하거나 직.병렬 접속으로 속도를 제어할수 있으며 아직까지 각종 산업분야의 속도제어에 직류 전동기가 5o[%] 이상을 차지하고 있으며 직류기의 특성과 시설로 보아 금세기 까지는 이용률이 많을 것으로 본다. This paper covers analysis and design of a DC compound motor. The devise that converted as machanical energy to electrical energy is a generator, The devise that converted as electrical energy to machanical energy is a motor. if a conductor moves in magnetic field, the electromotive forse is indused in a conductor. and current can flow in the conductor. if current flows in a conductor in the field, the electromagnetic forse is produced in a conductor, and motor can run by the electromagnetic forse. The speed can be controlled by varying the field current, armature resistance, terminal voltage and by direct / parralal connection of motors. Also Speed control of DC motor is very simple compared to any other motors. DC motor covers 50[%] up on control field of industrial part, and will be widely used till this century.
