본 고안은 모터용 회전자(Rotor)구조에 관한 것으로, 특히 마그네트(Magnet)를 로우터코어(Rotor Core)에 끼워 결합할 수 있게 하고 관성을 감소시킬 수 있게 한 회전자에 관한 것이다.The present invention relates to a rotor structure for a motor, and more particularly, to a rotor that allows a magnet to be coupled to a rotor core and reduces inertia.
첨부도면 제7도에는 종래에 사용되어온 로우터의 구조가 도시되어 있다.FIG. 7 shows a structure of a rotor conventionally used.
로우터는 샤프트(11)와 마그네트(12) 및 강판(13)으로 구성되어 있으며, 샤프트(11)는 마그네트(12)를 부착시키기에 용이한 형상으로 가공되어 있고 비자성체로된 강판(13)은 마그네트(12)의 바깥둘레에 감겨져 회전시 마그네트(12)가 이탈하는 것을 방지하여 준다.The rotor is composed of a shaft 11, a magnet 12 and a steel plate 13, the shaft 11 is processed into a shape that is easy to attach the magnet 12 and the non-magnetic steel plate 13 is It is wound around the outer circumference of the magnet 12 to prevent the magnet 12 from being separated during rotation.
그러나 상기와 같은 종래의 회전자는 마그네트를 강판(13)으로 고정시킴에 따라 자력의 손실이 발생하여 모터의 성능저하를 가져오게 되며, 샤프트(11)의 직경이 커서 관성이 증가하게 되는 결점이 있다.However, the conventional rotor as described above has a drawback that the magnetic force is lost by fixing the magnet to the steel sheet 13, resulting in a decrease in the performance of the motor, the diameter of the shaft 11 is increased, the inertia increases. .
제8도는 종래 사용되어온 로우터의 다른 예를 나타낸 단면도로서, 로우터는 샤프트(21), 로우터코어(22), 마그네트(23), 테이프(24)로 구성되며, 로우터코어(22)는 마그네트(23)를 부착시키기에 용이하도록 타발가공되어 있고 테이프(24)는 마그네트(23)의 원둘레면에 바인딩(Binding)되어 있다.8 is a cross-sectional view showing another example of a conventionally used rotor, in which the rotor is composed of a shaft 21, a rotor core 22, a magnet 23, and a tape 24, and the rotor core 22 is a magnet 23. ) And the tape 24 is bound to the circumferential surface of the magnet 23.
그러나 상기한 종래 회전자는 로우터코어(22)의 외경면에 마그네트(23)를 부착하는 구조이어서 회전자의 전체외경이 커지고 바인딩에 따른 작업공정의 증가와 생산성의 저하를 가져오게 된다.However, the conventional rotor has a structure in which the magnet 23 is attached to the outer diameter surface of the rotor core 22, so that the total outer diameter of the rotor is increased, resulting in an increase in work process and a decrease in productivity due to binding.
또한 상기한 제7도와 제8도의 종래 회전자는 마그네트가 수동적인 작업에 의해 부착됨에 따라 부착위치가 부정확해질 우려가 많고 이러한 경우 회전 언밸런스를 초래하게 되는 공통적인 문제점이 있었다.In addition, the conventional rotor of FIG. 7 and FIG. 8 has a common problem that the mounting position is often incorrect as the magnet is attached by manual operation, and in this case, rotation unbalance is caused.
본 고안의 목적은 로우터코어의 형상을 개량하여 회전자의 관성을 감소시킬 수 있게 한 것이다.An object of the present invention is to improve the shape of the rotor core to reduce the inertia of the rotor.
이와같은 본 고안의 목적에 따라 마그네트가 항상 정확한 위치에 고정될 수 있고 작업공정이 간소화 될 수 있는 모터용 회전자가 제공된다.According to the object of the present invention, a rotor for a motor is provided, in which a magnet can be fixed at an accurate position at all times and a work process can be simplified.
이하 본 고안의 바람직한 실시예를 첨부도면을 참조하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
첨부도면 제1도 내지 제5도는 본 고안의 일실시예를 나타낸 도면으로서, 제1도와 같이 로우터코어(2)의 중심부에는 샤프트(1)가 삽입될 수 있는 샤프트 삽입공(3)이 형성되어 있고 그 주위에는 마그네트 삽입구멍(4)과 관성의 감소를 위한 구멍(5)이 형성되어 있으며, 마그네트 삽입구멍(4)은 개방홈(6)에 의해 외부와 연통되어 있다.1 to 5 are views showing an embodiment of the present invention, the shaft insertion hole (3) in which the shaft (1) can be inserted is formed in the center of the rotor core (2) as shown in FIG. And a magnet insertion hole 4 and a hole 5 for reducing inertia are formed around the magnet insertion hole 4, and the magnet insertion hole 4 is in communication with the outside by an opening groove 6.
제2도는 로우터코어(2)의 양측에 결합되는 황동판의 사시도로서, 황동판(7)의 중심부에 샤프트 삽입공(8)이 형성되어 있다.2 is a perspective view of the brass plate coupled to both sides of the rotor core 2, the shaft insertion hole 8 is formed in the center of the brass plate (7).
제3도는 마그네트의 사시도로서, 마그네트(9)는 로우터코어의 마그네트 삽입구멍(4)에 끼워질 수 있도록 부채꼴 형상을 가진다.3 is a perspective view of the magnet, in which the magnet 9 has a fan shape to be fitted into the magnet insertion hole 4 of the rotor core.
따라서 제4도와 같이 샤프트(1)의 일측에 황동판(7)을 끼워 고정하고 로우터코어(2)를 소정의 칫수로 적층시킨 후 로우터코어(2)에 형성된 개방홈(6)을 통해 접착제를 분사하여 접착제가 마그네트 삽입구멍(4)의 둘레에 도포되고 이 상태에서 마그네트 삽입구멍(4)으로 마그네트(9)를 삽입하면 제5도와 같이 접착제층(10)에 의해 마그네트(9)가 마그네트 삽입홈(4)에 끼워져 고정된다.Therefore, as shown in FIG. 4, the brass plate 7 is fixed to one side of the shaft 1, the rotor cores 2 are laminated with a predetermined dimension, and then the adhesive is sprayed through the opening grooves 6 formed in the rotor cores 2. When the adhesive is applied around the magnet insertion hole 4 and the magnet 9 is inserted into the magnet insertion hole 4 in this state, the magnet 9 is inserted into the magnet insertion groove by the adhesive layer 10 as shown in FIG. (4) is fitted and fixed.
이렇게 마그네트(9)가 각 로우터코어(2)에 형성된 마그네트 삽입구멍(4)에 끼워져 고정된 후 황동판(7)을 끼워 고정하면 로우터의 제작이 완료되며, 마그네트 삽입구멍(4)의 크기를 마그네트의 크기 보다 약간 작게 형성하면 마그네트의 삽입식 마그네트 삽입공이 약간 확장되었다가 본래의 형태로 수축되려는 힘을 가지게 되므로 마그네트는 더욱 견고하게 고정된다.Thus, the magnet 9 is inserted into the magnet insertion hole 4 formed in each rotor core 2 and fixed, and then the brass plate 7 is inserted and fixed to complete the manufacture of the rotor, and the size of the magnet insertion hole 4 is magnetized. If the magnet is formed slightly smaller than the size of the magnet insertion hole of the magnet is slightly expanded and the force to shrink to its original shape, the magnet is more firmly fixed.
첨부도면 제6도는 본 고안의 다른 실시예를 나타낸 황동판과 로우터코어의 사시도로서, 이 실시예에서는 로우터코어(2)의 샤프트 삽입공(3) 주위에 다수의 마그네트 삽입구멍(4)이 형성되어 있고 황동판(7)에는 마그네트 삽입구멍과 같은 형상의 돌기(7a)가 형성되어 있다.6 is a perspective view of a brass plate and a rotor core according to another embodiment of the present invention, in which a plurality of magnet insertion holes 4 are formed around the shaft insertion hole 3 of the rotor core 2. The brass plate 7 is provided with a projection 7a having the same shape as the magnet insertion hole.
따라서 로우터코어(2)의 마그네트 삽입구멍(4)을 통해 마그네트를 삽입 고정할 수 있게 된다.Therefore, the magnet can be inserted and fixed through the magnet insertion hole 4 of the rotor core 2.
이상에서와 같이 본 고안은 로우터코어에 마그네트를 고정할 수 있으므로 마그네트의 고정을 위한 강판 결합 공정이자 테이프 바인더 공정이 불필요해지고 이에따라 공정단순화와 생산성의 향상을 가져오게 된다.As described above, the present invention can fix the magnet to the rotor core, which is a steel sheet joining process and a tape binder process for fixing the magnet, and thus, the process is simplified and the productivity is improved.
또한 기존의 회전자에 비해 관성이 감소하여 응답성이 향상되며, 마그네트의 착탈이 용이해져 마그네트의 불량으로 인한 회전자의 전체불량율을 감소시킬 수 있게 된다.In addition, the inertia is reduced compared to the conventional rotor, the response is improved, and the magnet is easily attached and detached, thereby reducing the total defective rate of the rotor due to the defective magnet.
