본 고안은 전통모터의 슬롯웨이지에 관한 것으로, 특히 외부의 충격에 의해 탈락되지 않아 실리콘강판과 코일사이의 절연을 완벽하게 달성할 수 있도록 된 전통모터의 슬롯웨이지에 관한 것이다.The present invention relates to a slot wedge of a traditional motor, and more particularly, to a slot wedge of a traditional motor that can be completely achieved by the insulation between the silicon steel sheet and the coil is not dropped by the external impact.

제1도는 종래 기술에 의한 슬롯웨이지의 형상을 도시한 사시도이고, 제2도는 종래 기술에 의한 슬롯웨이지가 실리콘강판의 슬롯에 삽입되어 코일이 감겨지는 상태를 도시한 부분절결사시도이다.FIG. 1 is a perspective view showing the shape of a slot wedge according to the prior art, and FIG. 2 is a partial cutaway perspective view showing a state in which a slot wedge according to the prior art is inserted into a slot of a silicon steel sheet and a coil is wound.

이에 도시된 바와 같이, 종래 기술에 의한 슬롯웨이지(1)(slotwedge)는 실리콘강판(2)의 슬롯(3,3')에 삽입되어 실리콘강판(2)과 코일(4) 사이를 절연시키는 역할을 하는 것으로 슬롯(3,3')의 내부에 삽입되도록 'ㄷ'자형으로 절곡형성된다.As shown in the drawing, the slot wedge 1 according to the related art is inserted into the slots 3 and 3 'of the silicon steel sheet 2 to insulate the silicon steel sheet 2 and the coil 4 from each other. It is formed to be bent in the '' 'shape so as to be inserted into the slot (3, 3').

상기와 같은 슬롯(3,3')는 실리콘강판(2)에 형성되어 있는 슬롯(3,3')에 별도의 삽입지그(미도시)를 사용하여 삽입되고, 이와 같이 슬롯웨이지(1)의 삽입이 되고 나면, 상기 강판(2)에 코일(4)을 감아주는 작업을 실시하게 된다.The slots 3 and 3 'as described above are inserted into the slots 3 and 3' formed in the silicon steel sheet 2 using a separate inserting jig (not shown). Once inserted, the coil 4 is wound around the steel sheet 2.

그러나,상기와 같은 종래 기술에 의한 슬롯웨이지(1)는 실리콘강판(2)과 코일(4)사이의 절연을 위한 실리콘강판(2)의 슬롯(3,3')에 삽입된 후, 코일(4)을 감는 작업을 수행하는 도중에 외부의 충격에 의해 유동되거나 탈락되어 코일권선작업의 작업성이 떨어지고 절연불량을 발생시키는 문제점이 있다.However, the slot wedge 1 according to the related art as described above is inserted into the slots 3 and 3 'of the silicon steel sheet 2 for insulation between the silicon steel sheet 2 and the coil 4, and then the coil ( 4) During the winding operation, there is a problem that the workability of the coil winding work decreases due to flow or drop due to an external impact and causes insulation failure.

그리고, 코일권선작업이 완료될 때 까지는 상기 슬롯웨이지(1)가 코일(4)과 실리콘강판(2) 사이에 정상적으로 위치되어 있으나 제품의 운반이나 운전중에 외부의 충격 및 제품자체의 진동등으로 인해 슬롯웨이지(1)가 정상적인 위치를 벗어나 실리콘강판(2)과 코일(4)사이의 절연불량을 발생시키게 되는 문제점이 있다.In addition, the slot wedge 1 is normally positioned between the coil 4 and the silicon steel sheet 2 until the coil winding operation is completed, but due to external shock and vibration of the product itself during transportation or operation of the product. There is a problem that the slot wedge 1 is out of the normal position to cause a poor insulation between the silicon steel sheet 2 and the coil (4).

특히 밀폐형 전동모터에서는 전동모터가 조립되고 나면 내부의 상태를 사용자가 관찰할 수 없어 상기와 같은 슬롯웨이지(1)의 탈락에 의한 절연불량을 사전에 감지할 수 없게 되어 절연불량에 의한 안전사고로 인명피해까지 가져올 수 있는 위험이 있다.In particular, in the sealed electric motor, after the electric motor is assembled, the user cannot observe the internal condition, and thus it is impossible to detect the insulation failure due to the drop of the slot wedge 1 as described above. There is a risk of injury to life.

따라서, 본 고안의 목적은 상기와 같은 종래 기술의 문제점을 해결하기 위한 것으로, 특히 코일과 실리콘강판 사이의 절연을 담당하는 슬롯웨이지의 유동 및 탈락을 방지하여 코일과 실리콘강판 사이의 절연을 확실하게 달성하는 것이다.Therefore, an object of the present invention is to solve the problems of the prior art as described above, and in particular, to prevent the flow and falling of the slot-way responsible for the insulation between the coil and the silicon steel sheet to ensure the insulation between the coil and the silicon steel sheet. To achieve.

상기와 같은 본 고안의 목적은 실리콘강판의 슬롯에 삽입되어 코일과 실리콘강판 사이의 절연을 담당하는 슬롯웨이지 몸체의 상단부에 하방향유동방지판을 형성하고, 하단부에 상방향유동방지판을 형성하여 구성됨을 특징으로 하는 전동모터의 슬롯웨이지에 의해 달성된다.An object of the present invention as described above is inserted into the slot of the silicon steel sheet to form a downward flow prevention plate in the upper end of the slot-way body responsible for the insulation between the coil and the silicon steel plate, to form an upward flow prevention plate in the lower end It is achieved by the slot of the electric motor, characterized in that configured.

상기 상,하방향유동방지판은 각각 복수개 형성된다.The plurality of upward and downward flow preventing plates are respectively formed.

상기한 바와 같은 본 고안에 의한 전동모터의 슬롯웨이지를 첨부된 도면에 도시된 실시례를 참고하여 상세히, 설명하면 다음과 같다.When described in detail, with reference to the embodiment shown in the accompanying drawings the slotway of the electric motor according to the present invention as described above.

제3도는 본 고안에 의한 전동모터의 슬롯웨이지의 형상을 도시한 사시도이고, 제4도는 본 고안에 의한 슬롯웨이지가 실리콘강판의 술롯에 삽입되어 코일이 감겨지는 상태를 도시한 부분절결사시도이다.Figure 3 is a perspective view showing the shape of the slot wedge of the electric motor according to the present invention, Figure 4 is a partial cutaway perspective view showing a state in which the coil is wound by the slot wedge is inserted into the slot of the silicon steel sheet according to the present invention. .

이에 도시된 바와 같이, 본 고안에 의한 전동모터의 슬롯웨이지(10)는 슬롯웨이지몸체(11)의 상단부에 하방향유동방지판(12,12')을 형성하고, 상기 몸체(11)의 하단부에는 상방향유동방지판(13,13')을 형성하여 구성된다. 상기 몸체(11)는 'ㄷ'자형으로 절곡형성되어 있으며 실리콘강판(2)의 슬롯(3,3')에 삽입되는 부분이다.As shown therein, the slot wedge 10 of the electric motor according to the present invention forms a downward flow prevention plate (12, 12 ') at the upper end of the slot-way body (11), the lower end of the body (11) Is formed by forming upward flow preventing plates 13 and 13 '. The body 11 is bent into a 'c' shape and is a portion inserted into the slots 3 and 3 'of the silicon steel sheet 2.

상기 상,하방향유동방지판(13,13')(12,12')은 각각 복수개 형성하는 것이 바람직하다.Preferably, a plurality of upper and lower flow preventing plates 13 and 13 'and 12 and 12' are respectively formed.

이하, 상기한 바와 같은 본 고안에 의한 전동모터의 슬롯웨이지의 작용효과를 설명한다.Hereinafter, the effect of the slot of the electric motor according to the present invention as described above.

먼저, 상기한 바와 같은 구조를 가지는 본 고안에 의한 슬롯웨이지(10)를 조립하는 것은 별도의 삽입지그(미도시)를 사용하여 슬롯웨이지(10)의 몸체(11)를 실리콘강판(2)에 형성되어 있는 슬롯(3,3')에 제4도에 도시된 바와 같이 삽입한 후, 코일권선작업을 하게 된다. 이때, 코일(4)을 권선하는 작업도중에는 상기 슬롯웨이지몸체(11)의 상단부에 형성되어 있는 하방향유동방지판(12,12')이 슬롯웨이지(10)의 하방향 유동을 억제하고, 슬롯웨이지몸체(11)의 하단부에 형성되어 잇는 상방향유동방지판(13,13')이 슬롯웨이지(10)의 상방향 유동을 억제하게 된다. 이와 같이 되면 코일권선작업중에 슬롯웨이지(10)가 유동되거나 탈락되는 일이 방지된다.First, assembling the slot wedge 10 according to the present invention having the structure as described above using a separate insertion jig (not shown) to the body 11 of the slot wedge 10 to the silicon steel sheet (2) After inserting the slots 3 and 3 'formed as shown in FIG. 4, the coil winding work is performed. At this time, during the winding of the coil 4, the downward flow preventing plates 12 and 12 'formed at the upper end of the slot-way body 11 suppress the downward flow of the slot-way 10, and the slot The upward flow preventing plates 13 and 13 ′ formed at the lower end of the wedge body 11 suppress the upward flow of the slot wedge 10. In this case, the slot wedge 10 is prevented from flowing or falling off during the coil winding operation.

또한, 일단 상기와 같이 코일권선작업을 완료하고, 전동모터를 완성하여 운반이나 사용시에 외부충격이나 사용중의 제품진동에 의해 슬롯웨이지(10)가 유동되거나 탈락되는 것이 상기 상,하방향유동방지판(13,13')(12,12')에 의해 억제된다.In addition, once the coil winding operation is completed as described above, the electric motor is completed and the slot wedge 10 is flowed or dropped by external shock or vibration of the product during use during transportation or use. It is suppressed by (13, 13 ') (12, 12').

위에서 상세히 설명한 바와 같은 본 고안에 의한 전동모터의 슬롯웨이지는 몸체 상하단부에 각각 하방향유동방지판과 상방향유동방지판을 구비하여 구성되므로 코일권선작업중에 슬롯웨이지가 유동, 탈락되는 일이 없고, 제품이 완성되어 운반이나 사용되는 경우에도 외부의 충격이나 제품진동에 의한 슬롯웨이지의 유동이나 탈락이 발생되지 않게 되므로 슬롯웨이지의 절연기능이 완벽하게 달성되는 효과가 있다.As described in detail above, the slotway of the electric motor according to the present invention is provided with a downward flow prevention plate and an upward flow prevention plate at upper and lower ends of the body, so that the slotway does not flow or drop during coil winding. Therefore, even when the product is completed and transported or used, since the flow or dropping of the slotwise does not occur due to external impact or product vibration, the insulation function of the slotwise is completely achieved.
