Description

영구자석 체인궤도 발전기Permanent Magnet Chain Track Generator
본 발명은 영구자석 체인궤도 발전기에 관한 것으로서, 더욱 상세하게는 일정 궤도를 그리며 회전하는 체인과 체인 사이에 N극과 S극을 동시에 사용하는 영구자석을 결합한 회전자 구조에, 외부로 돌출된 코일이 구비된 고정자와 규소강판 슬롯이 구비된 고정자를 용도에 맞게 적절히 사용하는 영구자석 체인궤도 발전기에 관한 것이다.The present invention relates to a permanent magnet chain track generator, and more particularly, a coil projecting outwards to a rotor structure that combines a permanent magnet using the N pole and the S pole at the same time between the chain and the chain rotating in a constant track. It relates to a permanent magnet chain orbital generator using the stator provided with this and the stator provided with a silicon steel sheet slot as appropriate.
일반적으로, 발전기는 회전자와 고정자가 구비되어 회전자에는 다수의 영구자석을 회전자 디스크에 배열 설치하여 회전축에 고정설치하고, 고정자는 상기 회전자와 격간으로 설치되어 회전자의 회전에 의해 발생하는 자기력선에 의해 전압이 유기되는 코일을 고정자 디스크에 배열설치하며, 이 고정자는 발전기 하우징에 고정설치되는 구조로 구성된다.In general, the generator is provided with a rotor and a stator, the rotor is installed in a plurality of permanent magnets arranged on the rotor disk fixed to the rotating shaft, the stator is installed between the rotor and the spacing generated by the rotation of the rotor The coil in which the voltage is induced by the magnetic force lines are arranged on the stator disk, and the stator is configured to be fixed to the generator housing.
이와 같은 기본적인 발전기의 구조는 상기 회전축에 외부 회전동력이 전달되어 고정자의 코일로 유기되는 전력을 출력시키는 것이다.The basic generator structure is such that external rotational power is transmitted to the rotating shaft to output power induced in the coil of the stator.
즉, 외부 회전력에 의해 상기 회전축이 회전되어 회전자가 회전되고, 회전자에 설치된 영구자석에 의해 유도되는 자기장이 고정자의 코일에 유기되면서 코일에서 전력의 출력을 얻게 된다.That is, the rotating shaft is rotated by external rotational force, the rotor is rotated, and the magnetic field induced by the permanent magnet installed in the rotor is induced in the coil of the stator to obtain the output of electric power from the coil.
상기한 발전기는 그 구조에 따라 AFPM 발전기와 영구자석 동기발전기로 구분된다.The generator is classified into an AFPM generator and a permanent magnet synchronous generator according to its structure.
토크(회전력)를 발생시키는 자속의 방향이 회전축과 같은 방향인 AFPM(Axial Flux Permanent Magnet) 발전기는 두 개의 디스크에 영구자석이 부착된 회전자의 공간에 부채꼴 모양의 복수의 코일을 원판형틀에 넣고 합성수지로 고정한 구조이다.Axial Flux Permanent Magnet (AFPM) generator, in which the direction of magnetic flux that generates torque (rotation) is in the same direction as the axis of rotation, inserts a plurality of fan-shaped coils into a disk frame in the rotor space where permanent magnets are attached to two disks. It is a structure fixed by synthetic resin.
또한, 회전자의 회전속도와 자기장의 회전속도가 같은 형태의 영구자석 동기발전기는 외부 원통형에 규소강판 슬롯의 고정자와 내부 원통형 면에 영구자석을 부착한 회전자로 이루어진 구조이다.In addition, the permanent magnet synchronous generator of the same type as the rotational speed of the rotor and the magnetic field is a structure consisting of a stator of the slotted silicon steel slot on the outer cylinder and a rotor attached to the permanent magnet on the inner cylindrical surface.
상기한 종래의 AFPM 발전기는 두 개의 회전자 디스크에 영구자석의 N극과 S극을 마주보게 하여 발전의 효율을 향상시킬 수 있으나 디스크 형상을 크게 하면 자석이 당기는 힘 때문에 고정자에 닿을 수 있어 디스크를 크게 하는데 제약이 있고, 복수의 부채꼴 모양의 코일을 원판형틀에 넣고 합성수지 같은 성분으로 밀봉하는 구조이기 때문에 회전자가 회전하면 자기장이 코일로 유기되면서 열이 발생할 때 열 냉각이 힘든 문제점이 있다.In the conventional AFPM generator, two rotor disks face the N pole and the S pole of the permanent magnet to improve the efficiency of power generation, but when the disk shape is enlarged, the magnet can reach the stator due to the pulling force of the disc. There is a limitation to increase, and since the structure is to seal the plurality of fan-shaped coils in a disk-shaped frame and sealed with a component such as synthetic resin, there is a problem that heat cooling is difficult when heat is generated as the magnetic field is induced into the coil when the rotor rotates.
또한, 상기한 영구자석 동기발전기는 초대형 발전기의 경우에 코일의 전류 흐름 향상과 철 손실이 적은 방향성 규소강판을 사용하여 전기효율을 향상시킬 수 있으나, 일반 발전기는 방향을 맞출 수 없어 방향성 규소강판 사용이 불가능하며, 회전자는 영구자석이 원통형 면에 부착되어 영구자석의 한쪽 면만 사용하게 되는 문제점이 있었다.In addition, the permanent magnet synchronous generator can improve the electrical efficiency by using a directional silicon steel plate with a low current loss and the current flow of the coil in the case of a super-large generator, but the general generator can not use the directional silicon steel sheet This is impossible, the rotor has a problem that the permanent magnet is attached to the cylindrical surface to use only one side of the permanent magnet.
본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로서, 영구자석의 N극과 S극을 동시에 사용하고 복수의 극이 배열되는 구조로 발전의 효율이 향상되어 작은 에너지로 많은 전력을 생산할 수 있다.The present invention has been made to solve the above-described problems, the structure of the N and S poles of the permanent magnet at the same time and a plurality of poles are arranged to improve the efficiency of power generation can produce a lot of power with a small energy.
또한, 영구자석과 영구자석 사이에 공간이 생겨 영구자석이 회전할 때 바람을 일으키면서 통풍이 되고 고정자는 외부로 돌출되어 자기장이 고정자의 코일로 유기되면서 발생하는 열을 효율적으로 냉각시킬 수 있다.In addition, a space is created between the permanent magnet and the permanent magnet to generate wind when the permanent magnet rotates, and the stator protrudes to the outside to efficiently cool the heat generated as the magnetic field is induced into the coil of the stator.
