이 발명은 스텝모터에 관한 것으로서, 보다 상세하게는 고도의 정밀제조기술 및 조립기술이 요구되는 스텝모터내의 상,하부 폴피스(pole piece)를 동일하게 제작하고 마그네트 착자를 반만큼 어긋나게 배치함으로써 제조공정을 간단히 하고 금형 및 생산비용을 절감토록 한 스텝모터에 관한 것이다.The present invention relates to a step motor, and more particularly, by manufacturing the same upper and lower pole pieces in a step motor requiring high precision manufacturing technology and assembling technology, and displacing the magnet magnets by half. It relates to a step motor that simplifies the process and reduces mold and production costs.
일반적으로 사무 자동화기기나 공장 자동화기기 등과 같이 위치의 정밀도와 자기절연이 중요시되는 제품에 사용되는 스텝모터는 제1도에 도시되어 있는바, 이에 대해 개략적으로 설명한다.In general, step motors used in products in which positional accuracy and magnetic insulation are important, such as office automation equipment or factory automation equipment, are illustrated in FIG.
제1도에 도시된 바와같이, 스텝모터의 로우터(10)는 일측면의 대략 중앙부에 소정길이로 돌출 형성된 축(12)이 회전가능하게 형성되어있다. 또한, 로우터(10)의 양편에는 외측방향으로 다수개의 돌기(14),(14a)가 형성된 한쌍의 폴피스(16),(16a)가 형성되어 있으며, 결합시에는 폴피스(16),(16a)의 내면이 서로 밀착하여 접합에 의하여 결합되는 것이다.As shown in FIG. 1, the rotor 10 of the step motor is rotatably formed with a shaft 12 protruding at a predetermined length in a substantially central portion of one side. In addition, a pair of pole pieces 16, 16a having a plurality of protrusions 14, 14a are formed on both sides of the rotor 10 in an outward direction, and the pole pieces 16, ( The inner surfaces of 16a) are bonded to each other by bonding.
한편, 한쌍의 폴피스(16),(16a)를 삽입하여 끼워지도록 원통형상의 보빈(18),(18a)이 관통되도록 형성되어 있다. 그리고, 보빈(18),(18a) 내부에 삽입된 폴리스(16),(16a)의 돌기(14)와 결합하는 프레임(20)은 내측면에 다수개의 돌출부(22)가 서로 엇갈리도록 돌출 형성되어 있다.On the other hand, cylindrical bobbins 18 and 18a are formed to penetrate through the pair of pole pieces 16 and 16a so as to be inserted therein. In addition, the frame 20 coupled to the protrusions 14 of the polices 16 and 16a inserted into the bobbins 18 and 18a is formed to protrude so that a plurality of protrusions 22 cross each other on the inner side. It is.
이와같이 구성된 스텝모터는 보빈(18),(18a)의 외측에 감겨진 코일(도시하지 않았음)에 외부 전원을 인가하면 폴피스(16),(16a)의 양돌기(14),(14a)에서 N,S극이 발생하여, 축(12)으로부터의 회전력을 전달받아 연속적인 펄스열에 의해 로우터(10)가 회전되는 것이다.The step motor configured in this manner is applied to the coils (not shown) wound around the outside of the bobbins 18 and 18a, and the positive protrusions 14 and 14a of the pole pieces 16 and 16a are applied. In the N, S pole is generated, the rotor 10 is rotated by the continuous pulse train receives the rotational force from the shaft (12).
그러나, 이러한 스텝모터는 제2도 및 제3도에 도시한 바와같이 상,하부 폴피스가 반만큼 어긋나 있는 바, 이로 인하여 금형이 달라지게 되며 이는 반드시 상부와 하부 폴피스를 나누어서 만들어야 하는 것이므로 제조비용이 상승될 뿐만 아니라 제품 품질의 저하요인으로 작용하게 되는 문제점이 있었다.However, as shown in FIG. 2 and FIG. 3, the step motor has the upper and lower pole pieces displaced by half, which causes the mold to be changed. Therefore, the step motor must be made by dividing the upper and lower pole pieces. In addition to the increase in cost, there was a problem that acts as a deterioration factor of product quality.
이 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 이 발명의 목적은 상,하부 폴피스를 동일하게 제작하고 마그네트 착자를 반만큼 어긋나게 함으로써, 제조공정을 간단히 하고, 금형 및 생산비용을 절감토록한 스텝모터를 제공함에 있다.The present invention has been made to solve the above problems, and an object of the present invention is to make the upper and lower pole pieces the same and to shift the magnet magnetization by half, thereby simplifying the manufacturing process and reducing mold and production costs. To provide a step motor.
상기와 같은 목적을 달성하기 위한 이 발명에 따른 스텝모터의 특징은, 스텝모터부에 상,하부 폴피스가 접합에 의해 조립 설치되고, 상기 폴피스의 외측에 코일이 감기는 보빈이 부착되며 마그네트가 형성된 로우터의 중앙에 축이 삽입되어 연속적인 펄스열에 의해 회전하는 스텝모터에 있어서: 상기의 상,하부 폴피스를 단일 금형에 의해 동일하게 형성시키고, 상기 폴피스에 대해 상기 마그네트의 N,S극의 위상을 약 1/2정도 회전시켜 엇갈리게 착자시켜서 된 점에 있다.A characteristic of the step motor according to the present invention for achieving the above object is that the upper and lower pole pieces are assembled and assembled by the step motor part, and a bobbin is attached to the outside of the pole pieces and a magnet is attached. In a step motor in which a shaft is inserted in the center of a rotor in which is formed and is rotated by a continuous pulse train, the upper and lower pole pieces are equally formed by a single mold, and the N, S of the magnet with respect to the pole pieces are formed. This is due to the fact that the magnets are alternately magnetized by rotating the phase of the pole about 1/2.
이하, 이 발명에 따른 스텝모터의 바람직한 하나의 실시예에 대하여 첨부도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a step motor according to the present invention will be described in detail.
제4도를 참조하면, 마그네트와 폴피스의 동작원리가 도시되어 있는 바, 이 발명은 제5도와 같은 착자 기술을 이용하여 상부와 하부에 형성된 마그네트의 N,S극의 위상을 반만큼 이동시킨 것이다. 또한, 제4도에 도시한 바와같이 폴피스에 있어서, 상부 폴피스(16)와 하부 폴피스(16a)를 동일하게 형성시켰다.Referring to FIG. 4, the operation principle of the magnet and the pole piece is shown. The present invention uses the magnetization technique as shown in FIG. 5 to shift the phases of the N and S poles of the magnets formed at the upper and lower portions by half. will be. In addition, as shown in FIG. 4, in the pole piece, the upper pole piece 16 and the lower pole piece 16a were formed in the same manner.
따라서, 상,하부 폴피스(16),(16a)를 동일하게 형성시킴으로써 금형이 한 개로 줄어들게 된다. 따라서, 상,하부 폴피스(16),(16a)가 조립되면 서로 어긋나지 않게된다. 그러나, 이들 폴피스의 내부에 놓이는 마그네트는 N,S극의 위상이 서로 엇갈려 있으므로 로터의 회전이 가능하게 된다.Therefore, by forming the upper and lower pole pieces 16, 16a in the same manner, the mold is reduced to one. Therefore, when the upper and lower pole pieces 16 and 16a are assembled, they are not shifted from each other. However, since the magnets placed inside these pole pieces are out of phase with each other, the rotor can be rotated.
이상에서와 같이 이 발명에 따른 스텝모터에 의하면, 상,하부 폴피스를 동일하게 형성하고, 마그네트의 위상을 반정도 회전시켜 착자함으로써 모터의 제조비용을 현저하게 절감할 수 있으며 또한, 제조공정을 단순하게 할 수 있는 효과가 있다.As described above, according to the step motor according to the present invention, the upper and lower pole pieces are formed in the same manner, and the magnet phase is rotated by half to magnetize, thereby significantly reducing the manufacturing cost of the motor. There is an effect that can be simplified.
