[고안의 배경][Design background]

본 고안은 개량된 고정자(an improved stator)를 갖는 브러쉬가 없는 직류모터(a non-brush D. C. motor)에 관한 것이다. 1988년에 출원된 대한민국 실용신안등록출원 제2629호에 따르면, 개량된 고정자를 갖는 브러쉬가 없는 직류모터는 측면(sides)들을 갖게 플라스틱(plastics)으로 만들어진 기부(a base)와, 그러한 기부의 둘레에 감겨 있는 코일(a coil)과, 기부의 그러한 양측면에 부착(fixing)된 한쌍의 자극(a pair of magnetic poles)을 각각 형상하고 있는 2개의 자극판(two magnetic polar plates) 및, 그러한 기부 한 측면에 연결된 회로기판(a circuit board)으로 구성된다. 상기 고안의 장점은 도료(varnish)를 사용함으로써 야기되는 환경오염이 없고, 설비비가 저렴하며, 제품불량율이 낮고, 제작이 용이하다는 것이다.The present invention is directed to a non-brush D. C. motor with an improved stator. According to Korean Utility Model Application No. 2629, filed in 1988, a brushless DC motor with an improved stator has a base made of plastics with sides and the perimeter of such a base. Two magnetic polar plates, each of which forms a coil wound around, a pair of magnetic poles fixed to both sides of the base, and one such base. It consists of a circuit board connected to the side. The advantages of the above-mentioned design is that there is no environmental pollution caused by the use of varnish, the equipment cost is low, the product defective rate is low, and the production is easy.

1991년에 출원된 대한민국 실용신안등록출원 제3705호에 기재된 또다른 브러쉬가 없는 직류모터는 2개의 측면 디스크가 자극판들이 결합할 수 있도록 V자홈(notches)들과 하부부재(feet)들을 갖는 고정자의 기부(a stator base)를 포함한다. 금속실린더(metal cylinder)의 얇은 가장자리(the thinner lip)를 확장(expanding)함으로써 상부자극판과 하부자극판이 고정자의 기부에 견고히 부착된다. 하우징의 기부(the housing base)의 중심축지주(the central shaft post)는 금속실린더의 내곽(the inner perimeter)을 통과할 수 있다.Another brushless direct-current motor described in Korean Utility Model Application No. 3705, filed in 1991, has a stator with V-shaped grooves and feet to allow two side disks to engage magnetic pole plates. It contains a stator base. By expanding the thinner lip of the metal cylinder, the upper and lower magnetic plates are firmly attached to the base of the stator. The central shaft post of the housing base may pass through the inner perimeter of the metal cylinder.

[고안의 개요][Outline of Design]

본 고안의 목적은 앞서 설명한 직류모터의 고정자를 개량하여 생산원가를 감소시키고 생산공정을 단순화하며 경쟁력을 높이기 위한 것이다.The purpose of the present invention is to improve the stator of the DC motor described above to reduce the production cost, simplify the production process and increase the competitiveness.

본 고안에 따른 개량된 고정자를 가진 브러쉬가 없는 직류모터는 선의 고리(wire rounds)들이 서로 접착될 수 있으면서도 서로로부터 절연될 수 있도록 선위에 있는 도료층(the varnish layer on the wire)을 약간 용해시키기 위해 알콜속에 담궈낸 도료가 칠해진 선(varnished wire)으로 감겨진 코일을 갖는 고정자를 포함한다. 그러한 코일의 특징은 그러한 코일이 어떤 기부(any base)에도 감겨 있지 않으며 절연효과를 유지하기 위해 외면상에서 절연용 도료층으로 코팅(coating)된다.Brushless DC motors with an improved stator according to the present invention slightly dissolve the varnish layer on the wire so that the wire rounds can be glued together and insulated from each other. And stators having coils wound by varnished wires dipped in alcohol. The feature of such coils is that they are not wound on any base and are coated with an insulating paint layer on the outside to maintain the insulation effect.

그러한 코일은 중심공(central opening)속에 있는 금속실린더 및 양측면에서의 2개의 자극판과 조합(combining)된다. 그리고 나서, 금속실린더는 고정자를 정위치에서 안정되게 유지하도록 하우징과 견고히 조합된다. 측(shaft)을 가진 회전자(a rotor)는 금속실린더의 내공(the inner openign)속에 부착된 베어링(a bearing)에 의해 지지된 축에 의해 고정자와 조합된다.Such a coil is combined with a metal cylinder in the central opening and two magnetic pole plates on both sides. The metal cylinder is then firmly combined with the housing to keep the stator stable in place. A rotor with a shaft is combined with the stator by an axis supported by a bearing attached into the inner openign of the metal cylinder.

이제, 본 고안을 도면을 참조하여 상세히 설명한다.The invention is now described in detail with reference to the drawings.

본 고안에 따른 고정자를 갖는 브러쉬가 없는 직류모터는 제1도와 같이 고정자속의 중앙의 둥근 구멍(11 : a central round opening)을 갖는 코일(1 : coil)을 포함한다. 그러한 코일은 미리 알콜속에 담궈낸 도료가 칠해진 전선(varnished electric wire)로 감겨지며, 그러므로, 그러한 도료가 칠해진 선으로 감겨진 고리(the wound rounds of varnished wrie)들은 서로 접착되어 중앙에 둥근 구멍(11)를 갖지만 기부(any base)를 전혀 갖지 않으면서도 둥글고 안정된 코일을 형성한다.Brushless DC motor having a stator according to the present invention includes a coil (1: coil) having a central round opening (11) of the stator flux as shown in FIG. Such coils are wound with a varnished electric wire previously immersed in alcohol, and therefore, the wound rounds of varnished wrie are glued together and rounded in the center (11). ) But form a round and stable coil with no base at all.

중앙의 둥근 구멍(11)은 금속실린더(12 : a metal cylinder)를 수용하고, 원통형 절연부(13 : a cylindrical insulator)가 그러한 금속실린더(12)의 중간부분의 둘레(around the middle portion)에 끼워지며, 2개의 환형 절연부(14 : two annular insulators)가 그러한 코일(1)의 양측면의 옆에 위치되고 그러한 금속실린더(12)의 양측부분의 둘레(around both side portions)에 끼워져서 그러한 코일(1)이 주위의 부품들로부터 절연될수 있게 한다. 또한, 그러한 코일(1)은 그러한 코일(1)의 외면(the outer surface)상에 코팅된 절연용 도료층에 의해 절연될 수 있다.The central round hole 11 receives a metal cylinder 12 and a cylindrical insulator 13 is formed around the middle portion of such a metal cylinder 12. Two annular insulators 14 are positioned next to both sides of such a coil 1 and fitted around both side portions of such a metal cylinder 12 such that the coil Allow (1) to be insulated from surrounding components. Furthermore, such coil 1 may be insulated by an insulating paint layer coated on the outer surface of such coil 1.

금속실린더(12)는 양단부(both end portions : 잔여부분)의 직경보다 중간부분의 직경이 더 크다. 그러한 중간부분은 코일(1)의 중앙의 구멍(11)속에 끼워지고, 양단부는 우측자극판(2)과 좌측자극판(3)의 중심공(the central holes)들의 직경보다 약간 큰 직경을 가지며, 따라서 양쪽의 자극판(2, 3)들은 금속실린더(12)의 양단부의 외면의 둘레에 끼워진 그러한 중심공들에 의해 금속실린더(12)와 억지끼움을 이루게 된다.The metal cylinder 12 has a larger middle diameter than the diameters of both end portions. Such an intermediate part is inserted into a hole 11 in the center of the coil 1, and both ends have a diameter slightly larger than the diameter of the central holes of the right magnetic pole plate 2 and the left magnetic pole plate 3. Thus, both magnetic pole plates 2 and 3 are forced into the metal cylinder 12 by such center holes fitted around the outer surface of both ends of the metal cylinder 12.

2개의 자극판(2, 3)과 코일(1) 및 금속실린더(12)가 함께 조립된 후에 회로기판(4 : a circuit board)이 좌측자극판(3)의 바깥쪽에 제공된다. 그리고 나서, 고정자가 완성된다.After the two magnetic pole plates 2, 3, the coil 1 and the metal cylinder 12 are assembled together, a circuit board 4 is provided on the outside of the left magnetic pole plate 3. Then the stator is completed.

이제, 금속실린더(12)의 좌측단부를 하우징의 둥근 돌출벽(51 : a round projecting wall)에 의해 둘러싸인 구멍속에 압입(forcing in)시킴으로써 그러한 완성된 고정자는 하우징(5)과 조합될 것이다. 둥근 돌출벽(51)의 내경은 금속실린더(12)의 단부의 직경보다 약간 작고, 그러므로, 그러한 금속실린더(12)는 둥근 벽(51)과 견고히 조합될 수 있다.Now, such a completed stator will be combined with the housing 5 by forcing in the left end of the metal cylinder 12 into a hole surrounded by a round projecting wall 51 of the housing. The inner diameter of the round protruding wall 51 is slightly smaller than the diameter of the end of the metal cylinder 12, and therefore such metal cylinder 12 can be firmly combined with the round wall 51.

축(61 : a shaft)을 갖는 회전자(6 : a rotor)는 금속실린더(12)의 내부의 구멍내에 견고히 유지된 베어링의 중심공을 통해 그러한 축(61)을 통과시킴으로써 고정자의 좌측면에 조합된다. 그리고 나서, 그러한 브러쉬가 없는 직류모터가 완성된다.A rotor 6 with a shaft 61 passes through the shaft 61 through the center hole of the bearing firmly held in the hole in the interior of the metal cylinder 12 to the left side of the stator. Combined. Then, a brushless dc motor is completed.

제2도 및 3도에서 알수 있듯이 본 고안에 다르면 기부(a base)가 생략되므로 제작시간 및 노력을 절약할 수 있으며, 그 재료와 주형에 관련된 생산원가를 절감한다.As can be seen in Figures 2 and 3, according to the present invention, a base can be omitted, thereby saving manufacturing time and effort, and reducing the production cost associated with the material and the mold.
