Abstract

A stator molding method in which the inner side of the stator is formed with a resin when the stator is molded. A projection rod(3a) of the mold(1) is inserted through a guide hole(2a) formed at the stator such that the coil(2) and a core(4) of the mold(1) are spaced apart from each other. Then a resin(5) is injected therebetween so that the inner side of the stator is formed with the resin(5), whereby the electrical short is prevented when a fluid flows into the inner side.

본 발명은 캔드형 펌프 전동기용(Canned Type Pump Motor) 고정자 성형방법에 관한 것으로서, 좀더 구체적으로는 고정자를 성형시에 고정자의 내경까지 수지로 성형시킬 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stator molding method for a canned type pump motor. More specifically, the stator can be molded to a resin up to the inner diameter of the stator during molding.

일반적으로 캔드형 펌프 전동기는 고정자와 회전자, 그리고 유체통로를 가진 원통형의 축, 원심력에 의해 유체압을 상승시키기 위한 베인을 가진 임펠러, 흡입구와 수평선상에 형성된 토출구로 구성되어 있다.In general, a canned pump electric motor is composed of a stator and a rotor, a cylindrical shaft having a fluid passage, an impeller having a vane for increasing the fluid pressure by centrifugal force, a suction port and a discharge port formed on a horizontal line.

따라서, 회전자에 의한 중공축과 고정된 임펠러가 회전하면 유체압이 상승되어 유체가 흡입구와 원통형의 축 내부에 형성된 유체통로를 통해 토출구로 이송되므로 설치 점유면적을 극소화 시킬 수 있는 장점이 있다. 이와 같은 캔드형 펌프 전동기는 유체를 축의 내부에 형성된 유체통로를 통해 수평선상으로 이송시키게 되므로 통상 고정자를 유체의 누설 등으로 인해 누전이 발생하는 것을 방지하기 위해 외부를 수지로 성형하게 된다.Therefore, when the hollow shaft and the fixed impeller rotated by the rotor, the fluid pressure is increased, so that the fluid is transferred to the discharge port through the fluid passage formed in the suction port and the cylindrical shaft, thereby minimizing the installation footprint. Since the canned pump electric motor transfers the fluid on the horizontal line through the fluid passage formed inside the shaft, the outside of the canned pump motor is molded into the resin in order to prevent a short circuit from occurring due to leakage of the fluid.

종래에는 이와 같은 캔드형 펌프 전동기에 사용되는 고정자를 수지로 성형하기위해 제6도에 도시한 바와같이 고정자의 철심(11) 내경과 일치되도록 가동측형판(12)에 코어(13)를 형성하여 코어(13)에 철심(11)의 내경이 끼워지도록 삽입한 후, 수지(14)로 성형하도록 되어 있다.Conventionally, the core 13 is formed on the movable side plate 12 so as to match the inner diameter of the iron core 11 of the stator, as shown in FIG. After inserting so that the internal diameter of the iron core 11 may be inserted into the core 13, it is shape | molded with resin 14. As shown in FIG.

그러나 이러한 종래의 성형방법은 고정자의 내경을 기준으로 성형하기 때문에 고정자를 수지로 성형완료하면 철심(11)의 내경이 공기와 접촉할 수 있도록 외부로 노출되어 유체가 고정자로 유입될 경우에는 누전이 발생하게 되고, 이에 따라 감전사고 등의 안전사고가 발생할 염려가 있었다.However, since the conventional molding method is molded based on the inner diameter of the stator, when the stator is formed of resin, the inner diameter of the iron core 11 is exposed to the outside so that a short circuit may occur when fluid is introduced into the stator. There was a risk of safety accidents such as electric shock.

본 발명은 종래의 이와 같은 점을 감안하여 안출한 것으로서, 고정자의 철심의 내경과 가동측형판의 코어 사이가 일정간격 유지되도록 고정자를 철심에 형성된 스크류가이드공이나 철심의 외경을 기준으로 가동측형판에 삽입하여 고정자 내경이 수지로 성형될 수 있도록하는 캔드형 펌프 전동기용 고정자 성형방법이 제공된다.The present invention has been made in view of the above-described conventional, the movable side plate on the basis of the screw guide hole formed on the iron core or the outer diameter of the iron core to maintain a constant interval between the inner diameter of the core of the stator and the core of the movable side plate Provided is a stator molding method for a canned pump electric motor which is inserted into a tube to allow a stator inner diameter to be molded into a resin.

이하, 본 발명을 일실시예로 도시한 첨부도면 제1도 내지 제3도를 참고로하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 through 3 of the accompanying drawings.

첨부도면 제1도는 본 발명의 일실시예를 도시한 단면도이고, 제2도는 고정자의 성형된 사시도이며 제3도는 몰드성형된 사시도로서, 가동측형판(1)에 철심(2)의 스크류가이드공(2a)이 기워질 수 있는 돌출봉(3a)을 가진 보스(3)가 다수개 형성되어 있고 보스(3)의 내측에는 철심(2)의 내경보다 약간 작은 코어(4)가 형성되어 있다.1 is a cross-sectional view showing an embodiment of the present invention, FIG. 2 is a molded perspective view of a stator and FIG. 3 is a molded perspective view of a screw guide of an iron core 2 on a movable side plate 1. A plurality of bosses 3 having protruding rods 3a on which 2a can be tilted are formed, and a core 4 slightly smaller than the inner diameter of the iron core 2 is formed inside the bosses 3.

따라서 돌출봉(3a)에 철심(2)의 스크류가이드공(2a)을 끼우면 철심(2)의 내경과 코어(4) 사이에 틈새(약0.3mm정도)가 발생된다. 이때 철심(2)의 저면은 보스(3)에 얹혀져 가동측형판(1)의 저면과 고정자가 일정간격을 유지하게 된다.Therefore, when the screw guide hole (2a) of the iron core (2) is inserted into the protrusion bar (3a), a gap (about 0.3mm) is generated between the inner diameter of the iron core (2) and the core (4). At this time, the bottom of the iron core (2) is placed on the boss (3) so that the bottom and the stator of the movable side plate (1) to maintain a constant interval.

이러한 상태에서 성형기에 의해 수지(5)가 유입되면 고정자의 외경과 내경이 제3도와 같이 수지로 성형되므로 유체의 이송시에 고정자에 유체가 유입되더라도 이로인해 누전이 되는 것을 방지할 수 있게 된다.In this state, when the resin 5 is introduced by the molding machine, the outer diameter and the inner diameter of the stator are molded into the resin as shown in FIG.

첨부도면 제4도 및 제5도는 본 발명의 다른 실시에를 도시한 단면도 및 성형된 고정자의 사시도로서, 가동측형판(1)에 철심(2)의 저면이 얹혀질 수 있도록 단턱(1a)을 형성함과 함께 코어(4)를 철심(2)의 내경과 틈새가 유지되도록 작게 형성하여 고정자를 수지(5)로 성형하면 제5도와 같이 되므로 고정자의 내경으로 유체가 유입될 경우에도 누전이 되는 것을 미연에 방지할 수 있게되는 효과가 있다.4 and 5 are cross-sectional views showing another embodiment of the present invention and a perspective view of a molded stator, wherein the step 1a is mounted so that the bottom surface of the iron core 2 can be placed on the movable side plate 1. In addition, the core 4 is formed small so that the inner diameter and the gap of the iron core 2 are maintained. When the stator is formed of the resin 5, it becomes as shown in FIG. There is an effect that can be prevented in advance.
