하이브리드 차량용 구동모터의 집중권 코일 권선장치 및 방법{Coil winding apparatus and method for motor of HEV}Coil winding apparatus and method for motor of HEV

본 발명은 하이브리드 차량용 구동모터의 집중권 코일 권선장치 및 방법에 관한 것으로서, 더욱 상세하게는 코일의 시작선을 권선 구간 밖으로 빼낸 상태로 코일을 스테이터 코어에 감음으로써, 시작선이 빠져나올 공간이 따로 필요하지 않으므로 기존 대비 원가상승 없이 점적률을 증대시킬 수 있도록 한 하이브리드 차량용 구동모터의 집중권 코일 권선장치 및 방법에 관한 것이다.The present invention relates to a concentrated winding coil winding apparatus and method of a drive motor for a hybrid vehicle, and more particularly, by winding the coil around the stator core in a state in which the starting line of the coil is pulled out of the winding section, a space from which the starting line is to be separated is separated. The present invention relates to a concentrated winding coil winding device and method of a driving motor for a hybrid vehicle that can increase the spot ratio without a cost increase since it is not necessary.

통상, 하이브리드 차량용 구동모터는 공간상에 제약이 심하여 최대한 박형으로 모터를 설계하고 있다. 이를 위해 스테이터 코어에 코일 권선시 동일한 공간에 최대한 점적률(구리선 단면적/구리선을 수납하는 공간으로 표시되는 수치)을 높여서 많이 감는 것이 중요하다.In general, a hybrid motor drive motor is designed to be as thin as possible because of the constraints in space. To this end, it is important to wind the coil by winding the stator core as much as possible in the same space as much as possible by increasing the area ratio (a number indicated by the copper wire cross-sectional area / space accommodating the copper wire).

종래의 코일 권선방법은 도 1에 도시한 바와 같이 코일(101) 권선시 코일 시작선과 끝선이 있는데, 시작선은 안쪽에 있고 끝선은 바깥쪽에 있다. 미설명부호 102는 스테이터 코어이다.In the conventional coil winding method, as shown in FIG. 1, when the coil 101 is wound, there is a coil start line and an end line. The start line is inward and the end line is outward. Reference numeral 102 is a stator core.

그러나, 상기 코일에 전원을 인가하기 위해서는 시작선이 안쪽에서 빠져나와야 되기 때문에 코일이 빠져나오는 공간에 대해서는 코일을 권선할 수 없다. 따라 코일이 빠져나오는 공간만큼 점적률이 떨어진다.However, in order to apply power to the coil, the starting line must be pulled out from the inside, so that the coil cannot be wound in the space from which the coil exits. As a result, the spot rate drops as much as the space from which the coil exits.

이와 같은 문제점을 해결하기 위해 특허출원 제2007-0129333호에는 알파 코일 권선 방법이 개시되어 있다. 상기 알파권선방법은 코일(111)의 시작선과 끝선이 모두 바깥쪽에 있기 때문에 시작선이 빠져나올 필요가 없다.In order to solve this problem, Patent Application No. 2007-0129333 discloses an alpha coil winding method. In the alpha winding method, since the start line and the end line of the coil 111 are both outward, the start line does not need to come out.

따라서, 기존 코일(101)의 권선방법보다 시작선이 빠져나오는 공간만큼 점적률을 증대시킬 수 있다.Therefore, it is possible to increase the spot ratio by the space in which the starting line exits from the conventional winding method of the coil 101.

그런데, 알파 권선 방법은 시작선이 빠져나오는 공간만큼 점적률을 증대시킬 수 있으나, 권선 설비 가격이 기존 대비 2배 이상이고, 권선 시간이 더 길어지는 단점이 있다.By the way, the alpha winding method can increase the spot ratio as much as the space from which the starting line exits, but the winding facility price is more than twice that of the existing, and the winding time is longer.

본 발명은 상기와 같은 점을 감안하여 안출한 것으로서, 코일의 시작선을 권선 구간 밖으로 빼낸 상태로 코일을 스테이터 코어에 감음으로써, 시작선이 빠져나올 공간이 따로 필요하지 않으므로 기존 대비 원가상승 없이 점적률을 증대시킬 수 있도록 한 하이브리드 차량용 구동모터의 집중권 코일 권선장치 및 방법을 제공하는데 그 목적이 있다.The present invention has been made in view of the above, by winding the coil to the stator core in a state in which the starting line of the coil is pulled out of the winding section, there is no need for a separate space for the starting line to exit, so there is no point in cost increase. An object of the present invention is to provide a central winding coil winding apparatus and method of a driving motor for a hybrid vehicle to increase the moment ratio.

상기한 목적을 달성하기 위한 본 발명은 하이브리드 차량용 구동모터의 집중권 코일 권선장치에 있어서,In the present invention for achieving the above object, in the concentrated winding coil winding device of a hybrid motor drive motor,

코일이 감겨지는 권선부; 상기 권선부의 양단에서 수직방향으로 형성된 플레이트; 및 상기 플레이트에 형성된 코일배출홈을 포함하고, 상기 코일은 시작선이 코일배출홈을 통해 플레이트 외부로 배출된 상태에서 권선되는 것을 특징으로 한다.A winding part in which a coil is wound; Plates formed in the vertical direction at both ends of the winding part; And a coil discharge groove formed in the plate, wherein the coil is wound in a state in which a starting line is discharged to the outside of the plate through the coil discharge groove.

본 발명의 다른 측면은 하이브리드 차량용 구동모터의 집중권 코일 권선방법에 있어서,In another aspect of the present invention, in the concentrated winding coil winding method of the drive motor for a hybrid vehicle,

플레이트에 형성된 코일배출홈을 통해 코일의 시작선을 플레이트 외부로 배출시키는 단계; 및 상기 코일의 시작선을 플레이트 외부로 배출시킨 상태로 권선부의 안쪽에서부터 코일을 감는 단계를 포함하여 이루어지는 것을 특징으로 한다.Discharging the starting line of the coil to the outside of the plate through the coil discharge groove formed in the plate; And winding the coil from the inside of the winding part in a state in which the start line of the coil is discharged to the outside of the plate.

이에 따라 본 발명에 따른 하이브리드 차량용 구동모터의 집중권 코일 권선장치 및 방법에 의하면, 처음부터 플레이트에 형성된 코일배출홈을 통해 코일의 시작선을 권선구간 외부로 배출시킨 상태에서 코일을 스테이터 코어에 권선함으로써, 권선구간에서 시작선이 빠져나올 공간이 별도로 필요하지 않으므로 기존대비 점적률을 증대시킬 수 있다.Accordingly, according to the concentrated coil winding device and method of the drive motor for a hybrid vehicle according to the present invention, the coil is wound around the stator core in a state in which the starting line of the coil is discharged to the outside of the winding section through the coil discharge groove formed in the plate from the beginning. By doing so, since the space for the start line to escape from the winding section is not necessary, it is possible to increase the spot ratio compared to the existing.

이하, 본 발명의 바람직한 실시예를 첨부도면을 참조로 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부한 도 3 및 도 4는 알파 코일 권선방법을 나타내는 사시도 및 단면도이고, 도 5는 본 발명의 일실시예에 따른 코일권선장치를 나타내는 도면이고, 도 6은 도 5에서 코일이 권선된 후 모습을 나타내는 도면이고, 도 7은 도 6의 우측면도이다.3 and 4 are a perspective view and a cross-sectional view showing an alpha coil winding method, Figure 5 is a view showing a coil winding apparatus according to an embodiment of the present invention, Figure 6 is a view after the coil is wound in Figure 5 7 is a right side view of FIG. 6.

본 발명은 하이브리드 차량용 집중권 방식의 구동모터 코일 권선시 점적률을 증대시킬 수 있도록 한 점에 주안점이 있다.The present invention has a main point to make it possible to increase the spot ratio during the winding of the drive motor coil of the concentrated winding method for a hybrid vehicle.

기존의 코일권선방법은 코일의 시작선이 안쪽에서 빠져나와야 하기 때문에 그 공간만큼 점적률이 감소되었다.In the conventional coil winding method, since the starting line of the coil has to come out from the inside, the spot ratio is reduced by the space.

그러나, 본 발명은 코일(10)의 시작선(10a)이 안쪽에서 빠져나올때 코일(10)을 권선하는 공간이 아닌 그 외 공간으로 빠져나오게 함으로써 시작선(10a)이 빠져 나올때 발생하는 점적률 감소를 방지할 수 있다.However, in the present invention, when the start line 10a of the coil 10 exits from the inside, the space rate that occurs when the start line 10a exits is reduced by allowing the coil 10 to exit out of the space for winding the coil 10. Can be prevented.

스테이터 코어(11)는 코일(10)이 감겨지는 권선부(12)와, 권선부(12)의 양단에서 수직방향으로 형성된 플레이트(13)를 포함하고, 권선부(12)에는 코일홈이 형성되어 코일 권선시 코일(10)이 옆으로 미끄러지는 것을 방지하도록 되어 있다.The stator core 11 includes a winding part 12 on which the coil 10 is wound, and a plate 13 formed in a vertical direction at both ends of the winding part 12, and a coil groove is formed in the winding part 12. The coil 10 is prevented from slipping sideways during coil winding.

여기서, 본 발명은 플레이트(13)에 코일배출홈이 형성되어 있어, 코일 시작선(10a)을 스테이터 코어(11) 외부, 즉 플레이트(13) 위로 빼냄으로써, 코일 시작선(10a)을 안쪽에서 빼냄으로 인해 권선불가능한 부위의 발생을 방지할 수 있다. 종래에는 코일 시작선(10a)을 스테이터 코어(11)의 플레이트(13) 안쪽에서 빼냄으로써 권선불가능한 부위가 발생하였다.Here, in the present invention, the coil discharge groove is formed in the plate 13, and by pulling the coil start line 10a out of the stator core 11, that is, above the plate 13, the coil start line 10a from the inside. By pulling out, it is possible to prevent the occurrence of an unwound portion. Conventionally, unwound portions occurred by pulling the coil starting line 10a from the inside of the plate 13 of the stator core 11.

기존의 스테이터 코어(11)에 코일(10)을 권선하는 방법은 코일(10)의 시작선(10a)을 플레이트(13) 안쪽에서부터 간격없이 감고, 바깥쪽 방향으로 여러 층으로 감은 다음, 시작선(10a)을 안쪽에서 빼냈으나, 본 발명은 코일(10)의 시작선(10a)을 처음부터 코일배출홈(13a)을 통해 플레이트(13) 바깥으로 빼낸 상태에서 코일(10)을 감음으로써, 시작선(10a)이 빠져나올 공간이 따로 필요하지 않으므로 점적률을 증대시킬 수 있게 되는 것이다.In the conventional method of winding the coil 10 to the stator core 11, the coil 10 may be wound around the start line 10a from the inside of the plate 13 without gap, and then wound in several layers in the outward direction, and then the start line. Although 10a was pulled out from the inside, the present invention wound the coil 10 in a state where the starting line 10a of the coil 10 was pulled out of the plate 13 through the coil discharge groove 13a from the beginning, Since the space for exiting the starting line 10a does not need to be separately, it is possible to increase the spot rate.

또한, 기존의 코일 권선 설비를 이용하므로 알파 권선 방법 대비 권선 설비 비용 및 권선 시간을 절감할 수 있다.In addition, by using the existing coil winding equipment it can reduce the winding equipment cost and winding time compared to the alpha winding method.

이상에서는 본 발명을 특정의 바람직한 실시예에 대하여 도시하고 설명하였으나, 본 발명은 이러한 실시예에 한정되지 않으며, 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 특허청구범위에서 청구하는 본 발명의 기술적 사상 을 벗어나지 않는 범위내에서 실시할 수 있는 다양한 형태의 실시예들을 모두 포함한다.While the invention has been shown and described with respect to certain preferred embodiments thereof, the invention is not limited to these embodiments, and has been claimed by those of ordinary skill in the art to which the invention pertains. It includes all the various forms of embodiments that can be implemented without departing from the spirit.
