Description

전동기의 고정자Stator of electric motor

제1도는 본 고안의 1 실시예를 이루는 고정자를 요크 내측에서 본 일부의 평면도.1 is a plan view of a part of the stator constituting one embodiment of the present invention seen from the inside of the yoke.

제2도는 제1도의 II-II 단면도.2 is a II-II cross-sectional view of FIG.

제3도는 본 고안의 다른 실시예를 표시하는 권선 도중의 평면도.3 is a plan view during windings showing another embodiment of the present invention.

본 고안은 전동기에 있어서의 피일드 코일의 접지 구조의 개량에 관한 것이다.The present invention relates to an improvement of the grounding structure of a feed coil in an electric motor.

종래 주지의 전동기에 있어서는 피일드코일을 접지하는 경우 보올코어에 층상을 이루고 권착되어진 피인드코일의 외주측단부를 요크로 접지하고 있었든 것이 일반적인 것이었다. 따라서 피일드코일의 내주측 단부를 외주까지 끌어내어 다른 회로에 접속하지 않으면 않되고 그렇게하기 위해서 피일드 코일의 내주측 단부를 절곡하여서 피일드 코일의 회전자 측단면부를 통하여 인출하고 양자의 사이에 절연재를 설치할 필요가 있었다. 또 피일드코일을 보올코어 및 요크에서 절연하는 면테이프 등의 절연재가 이 부분에서만 회전자 측으로 돌출하기 때문에 피일드코일의 인출부의 찌그러트리는 가공을 필요로 하였다. 그 결과 가공공수가 많아서 코스트가 높아졌다. 또 피일드코일의 외주측 단부를 요크의 내주에 접지하고 있기 때문에 요크를 고정하는 관통 보울트를 요크 내주에 통할 수가 없었고 따라서 요크 외주에 설치하지 않으면 않되기 때문에 외관의 대형화를 초래하고 있었다.In the conventional known motors, it is common to ground the outer circumferential end of the wound coil, which is layered on the bowl core and grounded, when the shielded coil is grounded. Therefore, it is necessary to draw the inner circumferential end of the feed coil to the outer circumference and connect it to another circuit. In order to do so, the inner circumferential end of the feed coil is bent and drawn out through the rotor side cross section of the feed coil, and the insulating material is formed between the two ends. I needed to install it. In addition, since an insulating material such as a cotton tape that insulates the coil from the core and the yoke protrudes to the rotor side only at this portion, crushing of the lead coil lead-out part is required. As a result, the cost is high due to the large number of machining operations. In addition, since the outer circumferential side of the feed coil was grounded on the inner circumference of the yoke, the through-bolt for fixing the yoke could not pass through the inner circumference of the yoke, and thus the exterior of the yoke had to be installed on the outer circumference of the yoke.

그래서 본 고안은 피일드코일을 그 내주측 단부로서 보올코어에 접지하므로서 피일드 코일의 내주측 단부를 외주에 인출하는 것을 중지하고 가공 공수의 대폭 저감을 목적으로 하는 것이다.Therefore, the present invention aims to stop the drawing of the inner circumferential side end of the feed coil to the outer circumference while reducing the feed coil to the bowl core as the inner circumferential side end thereof, and to significantly reduce the processing time.

본 고안의 1 실시예를 표시하는 제1도 및 제2도에 있어서 피일드코일(1)은 보올코어(2)에 절연재(3)를 협지하면서 층상을 이루며 밀착하여 권착되어 그 내주측단부(1a)는 피일드코일(1)의 내주측에 돌출하고 있어 보올코어(2)의 홈(2a)에 삽입되고 용접에 의해서 접지되어 있다.In FIG. 1 and FIG. 2 showing an embodiment of the present invention, the feed coil 1 is laminated in close contact with each other while sandwiching the insulating material 3 on the bowl core 2, and the inner circumferential side end portion thereof ( 1a protrudes on the inner circumferential side of the feed coil 1 and is inserted into the groove 2a of the bowl core 2 and grounded by welding.

(4)는 면테이프 등의 절연재로서 층상으로 권착된 피일드코일(1)을 유지하고 또 피일드코일(1)을 요크(5) 및 보올코어(2)에 대하여 절연하고 있다.(4) holds the wound coil 1 wound in a layer as an insulating material such as cotton tape, and insulates the wound coil 1 from the yoke 5 and the bowl core 2.

보올코어(2)는 피일드코일(1)이 권착되고 내주측 단부(1a)가 접지되어진 후 요크(5)의 내주에 용접등에 의해서 고정되어 접지되어 있다. 그리고 피일드코일(1)의 외주측단부(1b)는 도시되지 않은 타회로에 접속된다.The bow core 2 is fixed to the inner circumference of the yoke 5 and grounded after the feed coil 1 is wound and the inner circumferential side end 1a is grounded. The outer circumferential side end portion 1b of the feed coil 1 is connected to another circuit not shown.

또한 상기 실시예에서는 피일드코일의 접지 방법을 용접으로 하였으나 납땜 조입 또는 보올코어와 요크에 의한 압착으로 접지할 수도 있다. 또 상기 실시예에서는 보올코어에 홈을 설치하였으나 제3도와 같이 절연피막을 지닌 피일드코일(1)의 일단(1a)을 보올코어(2)에 용접하고 보올코어(2)에 직접 피일드코어(1)를 권착하여도 좋다.In addition, in the above embodiment, the method of grounding the coil is welded, but it may be grounded by soldering joining or pressing by a bowl core and yoke. In the above embodiment, the groove is provided in the bowl core, but as shown in FIG. 3, one end 1a of the coated coil 1 having the insulating coating is welded to the bowl core 2, and the feed core is directly connected to the bowl core 2. You may wind up (1).

상술한 바와같이 본 고안은 피일드코어의 내주측 단부를 요크에 고정되어진 보올 코어에 접속하고 타회로와의 접속을 피일드코일의 외주측 단부로 행하는 것을 특징으로 한 것으로 이것에 의하면 피일드코일의 내주단부를 외주에까지 인출하지 않아도 좋기 때문에 이 부분의 가공공수의 대폭 저감이라고 하는 효과가 얻어진다.As described above, the present invention is characterized in that the inner circumferential end of the shielded core is connected to the bowl core fixed to the yoke and the other circuit is connected to the outer circumferential side of the shielded coil. Since it is not necessary to pull out the inner peripheral end to the outer periphery, the effect of drastically reducing the processing time of this part is obtained.

또 피일드코일의 외주측의 스페이스가 확보되므로 요크를 고정하는 관통보울트를 요크 내주측에 통하게 하여 전동기의 소형화를 도모할 수가 있다.In addition, since the space on the outer circumferential side of the shielded coil is secured, the through-bolt for fixing the yoke is allowed to pass through the inner circumferential side of the yoke, thereby miniaturizing the motor.
