본 발명은 리니어 모터의 전기자 철심의 제작방법에 관한 것으로 방사형 적층을 정밀하고 용이하게 구성하기 위한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an armature core of a linear motor, in order to precisely and easily configure a radial stack.

종래 전기자 철심의 방사형 적층방식은 제1도와 같이 전기자 철심(1)을 철심홀더(2)를 중심으로 원주방향으로 일정하게 세운다음 윗부분이나 이래부분을 단순히 누르는 힘만으로 고정시키고 간단한 지그나 수작업으로 철심 적층물을 제작하고 있다.In the conventional radial lamination method of the armature iron core, the armature core 1 is erected in a circumferential direction around the iron core holder 2 as shown in FIG. The laminate is produced.

이러한 전기자 철심(1)의 적층형태는 제2도와 같이 철심홀더(2)에 방사상으로 분포되어 고정되고 각각의 철심(1)은 서로 동일한 각도(θ)와 간격을 유지하도록 맞춰져 있다.The stacking type of the armature core 1 is radially distributed and fixed to the iron core holder 2 as shown in FIG. 2, and the respective iron cores 1 are fitted to maintain the same angle and spacing from each other.

각 철심(1)의 적층간격과 각도(θ)는 전기자의 자기광 발생 분포를 결정하여 엑츄에이터 가동에 영향을 준다.The lamination spacing and angle θ of each iron core 1 determine the distribution of the magneto-optical generation of the armature to influence the actuator operation.

따라서 전기자 철심은 서로 이웃하는 각 철심간의 간격과 설치각도(θ)가 균등하게 맞춰질 때 엑츄에이터의 가동을 안정화 시킬 수 있게 된다.Therefore, the armature core can stabilize the operation of the actuator when the spacing between each adjacent iron core and the installation angle θ are equally matched.

그러나 종래의 전기자 철심적층방법과 이에 따른 전기자 철심의 적층상에 의하면 날개의 각 철심(1)을 철심홀더(2)를 중심으로 지그나 수작업으로 방사상으로 배치하게 되어 있어 작업성 저하 문제 뿐만 아니라 각 철심간의 균일한 각도의 적층이 어려운 문제점이 있었다.However, according to the conventional method of laminating the core of the armature and the lamination of the armature core accordingly, each iron core 1 of the wings is radially disposed by a jig or a hand around the iron core holder 2, thereby reducing the workability problem as well. Lamination of uniform angles between iron cores has been a problem.

따라서, 본 발명의 목적은 각 전기자철심의 배치간격 및 각도를 균일하게 유지시키는 데 있다.Accordingly, it is an object of the present invention to uniformly maintain the spacing and angle of placement of each armature core.

본 발명의 다른 목적은 철심 배치 작업성을 좋게 하는데 있다.Another object of the present invention is to improve iron core placement workability.

이러한 목적 및 다른 목적들은 전자석등 자속발생 장치를 사용하여 자속을 철심에 통과시킴으로서 철심에 자성이 생기게 하여 각각의 철심이 서로의 반발력으로 방사형의 배치형태를 갖추게 하여 철심홀더에 고정시킴으로서 달성된다.These and other objects are achieved by using a magnetic flux generating device such as an electromagnet to pass the magnetic flux through the iron core to create magnetism in the iron core so that each iron core has a radial arrangement with mutual repulsion and is fixed to the iron core holder.

본 발명에 의한 전기자 철심의 적층은 제3도와 같은 자속발생장치를 사용한다.Lamination of the armature core according to the present invention uses a magnetic flux generating device as shown in FIG.

상기 자속발생장치는 AC 또는 DC전원이 사용되며 자속을 발생시키기 위한 전자석(3)이나 영구자석이 갖추어 지고 자속이 흐르는 제1요크(4) 및 제2요크(5)가 있다.The magnetic flux generating device uses an AC or DC power source, and is provided with an electromagnet 3 or a permanent magnet for generating magnetic flux, and a first yoke 4 and a second yoke 5 through which magnetic flux flows.

상기 자속발생장치에서 전자석(3)에 전류가 흐르면 자속(M)이 발생한다.When the current flows through the electromagnet 3 in the magnetic flux generating device, magnetic flux M is generated.

이 자속은 제1,2요크(4)(5)와 철심(1)을 통과하며 순환한다.This magnetic flux circulates through the first and second yokes (4) (5) and the iron core (1).

이 과정에서 전기자 철심(1)에 자속(M)이 흐르게 되면 각각의 전기자 철심(1)은 자성을 띄게 된다.In this process, when the magnetic flux M flows through the armature core 1, each armature core 1 becomes magnetic.

전기자 철심을 통과하는 자속은 방사형 형태를 띄게 되며 자성을 가진 전기자 철심(1)은 각각이 하나의 자석이라고 볼 수 있다.The magnetic flux passing through the armature core has a radial shape, and the armature core 1 having magnetic properties can be regarded as one magnet.

이때 각각의 전기자 철심(1)은 방향이 동일한 자석이기 때문에 철심간에서 서로 반발력이 작용한다.At this time, since the armature cores 1 are magnets in the same direction, the repulsive force acts between the iron cores.

따라서 홀더(2)를 둘러싸고 있는 철심(1)들은 360°에 걸쳐 서로의 반발력때문에 일정한 간격으로 펼쳐진다.The iron cores 1 surrounding the holder 2 are thus unfolded at regular intervals due to the repulsive force of each other over 360 °.

이 상태에서 에폭시등 철심고정장치를 부가하여 전체철심을 요크(4)(5)에서 분리 시킨 후 전기자 철심을 완성한다.In this state, an iron core fixing device such as epoxy is added to separate the entire core from the yoke (4) and (5), and then complete the armature core.

방사형 전기자 철심의 완성된 적층형태를 제4에서 나타내었다.The completed lamination form of the radial armature core is shown in the fourth.

이와 같은 형태의 전기자 철심의 적층형태는 서로 이웃하는 각 철심간의 간격과 적층간 각도가 동일한 배치형태를 갖게 된다.The stacked form of the armature core of this type has an arrangement form in which the spacing between the adjacent iron cores and the lamination angle are the same.

따라서 지그를 이용하여 철심을 배치하는 방법이나 철심을 낱개로 수작업으로 배치하는 방법보다는 더욱 정교한 배치간극과 균등한 적층 배열상을 얻을 수 있었다.Therefore, it was possible to obtain a more precise arrangement gap and evenly stacked arrangement image than the method of arranging iron cores by a jig or manually arranging iron cores individually.

또한 홀더(2)를 둘러싸고 있는 각 철심(1)들이 360°에 걸쳐 서로의 반발력 때문에 일정한 간격으로 펼쳐지면 철심(1)을 홀더(2)에 에폭시 또는 접착제를 이용하여 고정시키고 자속발생장치의 요크(4)(5)에서 분리시키면 전기자철심(1)의 적층이 완성되는 제작과정을 갖게 됨으로써 철심(1)의 배치작업을 포함한 철심 적층을 위한 작업공수가 줄어드는 비교적 간단한 제작공정을 통해 적층이 완료되는 결과를 얻을 수 있다.In addition, when the iron cores 1 surrounding the holder 2 are unfolded at regular intervals due to mutual repulsive force over 360 °, the iron core 1 is fixed to the holder 2 by using epoxy or an adhesive and the yoke of the magnetic flux generating device When separated from (4) (5), the lamination of the armature cores (1) is completed, and thus the lamination is completed through a relatively simple manufacturing process that reduces the labor time for lamination of the iron cores including the arrangement of the iron cores (1). Results.

이와 같은 본 발명의 전기자코일 적층방법에 의하면 각 철심간의 간격을 일정하게 유지하여 균일한 각도의 철심적층이 가능하고 각 철심의 방사형 배치 작업이 필요없이 간단히 철심을 적층할 수 있어 철심제작 작업성을 좋게 할 수 있다.According to the electromagnet lamination method of the present invention, it is possible to stack iron cores at a uniform angle by keeping the intervals between the iron cores constant, and to simply stack the iron cores without the need for radial arrangement of the iron cores. You can do it nicely.
