본 발명은 발전기에 관한 것으로, 보다 상세하게는 회전자의 회전저항을 줄여 저속회전으로 전기를 발생시킬 수 있는 저속발전기에 관한 것이다.The present invention relates to a generator, and more particularly, to a low speed generator capable of generating electricity at low speed by reducing the rotational resistance of the rotor.

발전기는 기계적 에너지를 전기적 에너지로 변환하는 기기로, 자기장을 만들기 위한 자석과 기전력을 발생시키는 도체를 포함하여 자석 또는 도체가 회전하도록 구성되며, 도체가 정지하고 자기장이 회전하는 회전계자형발전기와 도체가 회전하고 자기장이 정지하는 회전전기자형발전기가 있다.A generator is a device that converts mechanical energy into electrical energy, and includes a magnet for generating a magnetic field and a conductor for generating an electromotive force such that a magnet or a conductor rotates, and a rotating field generator and a conductor in which the conductor stops and the magnetic field rotates. There is a rotating armature generator which rotates and stops the magnetic field.

발전기에서 생성되는 기전력의 크기는 자기장의 세기와 도체의 길이 및 자기장과 도체의 상대속도에 비례하기 때문에 자기장의 세기를 높이거나 도체를 길게 형성하거나 또는 자기장과 도체의 상대속도를 크게 함으로써 기전력을 높일 수 있으며, 통상적으로 자기장과 도체의 상대속도를 크게 하여 기전력을 높이고 있다.Since the magnitude of the electromotive force generated by the generator is proportional to the strength of the magnetic field and the length of the conductor and the relative speed of the magnetic field and the conductor, the electromotive force is increased by increasing the strength of the magnetic field, forming the conductor long, or increasing the relative speed of the magnetic field and the conductor. In general, the relative speed of the magnetic field and the conductor is increased to increase the electromotive force.

자기장과 도체의 상대속도를 높이기 위해서는 회전자의 회전속도를 높여야 하는 데 이럴 경우 고속회전을 요하기 때문에 조력, 풍력 및 도로발전과 같이 저속회전력을 인가하는 경우 원하는 기전력을 얻을 수 없었다.In order to increase the relative speed of the magnetic field and the conductor, it is necessary to increase the rotational speed of the rotor. In this case, high-speed rotation is required. Therefore, when applying low-speed rotational power such as tidal power, wind power, and road power generation, the desired electromotive force cannot be obtained.

이에 저속회전력을 사용하여 원하는 기전력을 얻을 수 있는 저속발전기가 개발되었으며, 그 일례인 등록실용신안 제20-0217447호의 「저속발전기」가 도 4에 도시되어 있다.Accordingly, a low speed generator capable of obtaining desired electromotive force using a low speed rotational power has been developed. An example of the "low speed generator" of the Utility Model Registration No. 20-0217447 is shown in FIG. 4.

도 4의 저속발전기는 회전자(10)와 고정자(20)를 서로 역방향으로 회전시킴으로써 저속회전력에서 높은 기전력을 얻는 구조로, 회전통(40)에 고정축(1)이 회전가능하게 고정되고, 고정축(1)에는 정류자편(12)이 일측에 형성된 회전자(10)가 설치되며, 회전자(10)의 외측에 위치하도록 원통형의 고정자(20)가 고정축(1)에 설 치되고, 회전통(40)의 회전동력을 서로 역방향으로 회전하도록 회전자(10)와 고정자(20)에 전달하는 기어열이 설치되어 있다.The low speed generator of FIG. 4 has a structure in which a high electromotive force is obtained at low speed rotational power by rotating the rotor 10 and the stator 20 in opposite directions, and the fixed shaft 1 is rotatably fixed to the rotating cylinder 40. The fixed shaft (1) is provided with a rotor (10) having a commutator piece (12) formed on one side, and a cylindrical stator (20) is installed on the fixed shaft (1) so as to be located outside the rotor (10). The gear train is transmitted to the rotor 10 and the stator 20 so as to rotate the rotational power of the rotary cylinder 40 in the opposite direction.

그러나, 상술한 종래의 저속발전기는 상대속도를 크게 하기 위하여 다수의 기어열을 사용하여 회전자와 고정자를 역방향으로 회전시키고 있기 때문에 그 구성이 복잡하고 조립이 어려웠으며 무게가 무거웠고 제조가가 비쌌다.However, since the above-described conventional low speed generator rotates the rotor and the stator in the reverse direction by using a plurality of gear trains in order to increase the relative speed, the configuration is complicated, assembly is difficult, the weight is heavy, and the manufacturing is expensive. .

본 발명은 상술한 종래기술의 문제점을 해결하기 위하여 창안한 것이다. 본 발명의 목적은 간단한 구성의 기어결합을 통해 회전자와 회전통을 동시에 회전시켜 회전자의 회전저항을 줄임으로써 저속회전에서 원하는 기전력을 얻을 수 있는 저속발전기를 제공하는 것이다.The present invention has been made to solve the above-mentioned problems of the prior art. An object of the present invention is to provide a low speed generator that can achieve the desired electromotive force in low speed rotation by reducing the rotational resistance of the rotor by simultaneously rotating the rotor and the rotating cylinder through the gear combination of a simple configuration.

상술한 본 발명의 목적을 달성하기 위하여, 본 발명은 외부동력에 의해 회전하는 회전축과, 회전축과 고정되게 결합되어 회전축에 의해 회전하는 원통형의 회전자과, 회전자의 내측면에 설치되는 자석과, 회전자의 외측으로 회전축과 회전 가능하게 결합되는 원통형의 고정자와, 고정자의 내측면에 설치되며 외부 배선과 연결되는 도체와, 고정자의 외측으로 회전축과 고정되게 결합되어 회전축에 의해 회전하는 원통형의 케이싱을 포함하는 것을 특징으로 하는 저속발전기를 제공한다.In order to achieve the above object of the present invention, the present invention is a rotating shaft that rotates by external power, a cylindrical rotor fixedly coupled to the rotating shaft and rotated by the rotating shaft, a magnet installed on the inner surface of the rotor, Cylindrical stator that is rotatably coupled with the rotating shaft to the outside of the rotor, conductors installed on the inner side of the stator and connected to the external wiring, and cylindrical casing that is fixedly coupled to the rotating shaft to the outside of the stator to rotate by the rotating shaft It provides a low-speed generator comprising a.

본 발명의 저속발전기는 내부에 발생하는 열을 외부로 방출하기 위하여 고정자 및 케이싱 중 적어도 하나의 표면에 다수의 관통구를 형성할 수 있다.The low speed generator of the present invention may form a plurality of through holes on at least one surface of the stator and the casing in order to discharge heat generated therein to the outside.

또한, 고정자는 그 양측면의 중앙을 베어링을 매개로 회전축에 결합할 수 있 다.In addition, the stator may be coupled to the axis of rotation via a bearing in the center of both sides.

또한, 고정자는 그 일측에 고정기어를 설치하며 케이싱의 내측면에 고정기어와 맞물려 회전하는 다수의 회전기어를 설치할 수 있다.In addition, the stator may be provided with a fixed gear on one side thereof and may be provided with a plurality of rotary gears to rotate in engagement with the fixed gear on the inner surface of the casing.

또한, 고정자를 회전축을 회전가능하게 지지하는 외부받침대에 고정되게 결합할 수 있다.In addition, the stator may be fixedly coupled to the outer support for rotatably supporting the rotating shaft.

이하, 첨부한 도면을 참조로 본 발명의 바람직한 실시예에 따른 저속발전기에 대하여 상세하게 설명한다.Hereinafter, a low speed generator according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

도 1 내지 도 3에 도시한 바와 같이, 본 발명의 바람직한 실시예에 따른 저속발전기(100)는 회전축(101), 회전자(110), 고정자(130) 및 케이싱(150)을 포함한다.As shown in Figures 1 to 3, the low speed generator 100 according to a preferred embodiment of the present invention includes a rotating shaft 101, a rotor 110, a stator 130 and a casing 150.

회전축(101)은 외부의 동력발생수단에 의해 발생하는 동력에 의해 회전하며, 그 양단부가 회전축지지대(102)에 의해 회전 가능하게 지지된다.The rotating shaft 101 is rotated by the power generated by the external power generating means, and both ends thereof are rotatably supported by the rotating shaft support 102.

회전자(110)는 원통형으로 그 중앙을 관통하도록 회전축(101)에 고정되게 결합되며, 그 외주면에 수분할, 본 실시예에서는 12분할된 자석(111)이 부착된다.The rotor 110 is cylindrically fixed to the rotating shaft 101 so as to penetrate through the center thereof, and the magnet 111 divided into 12 in this embodiment is attached to the outer circumferential surface thereof.

고정자(130)는 중공원통형으로 회전자(110)의 외측에 위치하며, 비도체로 제조한다.The stator 130 is located in the outer side of the rotor 110 in a hollow cylinder shape, and is made of a non-conductor.

고정자(130)의 양측단에는 나사(131) 등의 결합수단에 의해 측판(133,134)이 결합되며 측판(133,134)의 중앙에는 베어링(135,136)이 장착된다.Side plates 133 and 134 are coupled to both side ends of the stator 130 by coupling means such as screws 131, and bearings 135 and 136 are mounted at the centers of the side plates 133 and 134.

베어링(135,136)은 고정자(130)와 회전축(101)을 서로 회전 가능하게 결합하기 위한 수단이며, 베어링(135,136)으로 인해 회전축(101)의 회전에 의해 고정자 (130)가 영향을 받지 않는다.The bearings 135 and 136 are means for rotatably coupling the stator 130 and the rotation shaft 101 to each other, and the stator 130 is not affected by the rotation of the rotation shaft 101 due to the bearings 135 and 136.

측판(134)에는 고정자(130)를 지지하기 위한 중공원통형의 고정자지지부재(137)가 고정되게 결합되며, 고정자지지부재(137)는 외부의 회전축받침대(102)에 고정되게 결합된다. 또한, 고정자지지부재(137)에는 고정기어(138)가 고정되게 결합되며, 그 내부를 관통하도록 회전축(101)이 회전 가능하게 결합된다. 따라서, 고정자(130)는 회전축받침대(102)에 고정되게 결합되는 고정자지지부재(137)에 의해 회전축(101)의 회전력에 상관없이 항상 정지된 상태를 유지하게 된다. Side plate 134 is a stator support member 137 of the hollow-cylindrical cylindrical shape for supporting the stator 130 is fixedly coupled, the stator support member 137 is fixedly coupled to the external rotary shaft support (102). In addition, the stator support member 137 is fixedly coupled to the fixed gear 138, the rotating shaft 101 is rotatably coupled to penetrate the inside thereof. Accordingly, the stator 130 is always maintained in a stopped state regardless of the rotational force of the rotation shaft 101 by the stator support member 137 fixedly coupled to the rotation shaft support 102.

또한, 고정자(130)의 내주면에는 다수의 막대형 도체(141)가 부착된다. 도체(141)에는 코일(142)이 권선되며 코일(142)은 격판(134)을 관통하여 격판(154)과 고정자지지부재(137) 사이의 공간을 통해 외부로 인출되는 배선(143)과 연결된다. 따라서, 코일(142)에 발생되는 전류가 배선(143)을 따라 외부로 전달될 수 있다.In addition, a plurality of rod-shaped conductors 141 are attached to the inner circumferential surface of the stator 130. The coil 142 is wound around the conductor 141, and the coil 142 is connected to the wiring 143 which is drawn out through the space between the diaphragm 154 and the stator support member 137 through the diaphragm 134. do. Therefore, the current generated in the coil 142 may be transmitted to the outside along the wiring 143.

케이싱(150)은 중공원통형으로 고정자(130)의 외측에 위치하며, 철로 제조한다.The casing 150 is located in the outer side of the stator 130 in a hollow cylinder shape, and is made of iron.

케이싱(150)의 양측단에는 나사(151) 등의 결합수단에 의해 측판(153,154)이 고정되게 결합되며, 측판(153,154)에는 그 중앙을 관통하도록 회전축(101)이 결합된다.The side plates 153 and 154 are fixedly coupled to both side ends of the casing 150 by means of coupling means such as screws 151, and the rotating shaft 101 is coupled to the side plates 153 and 154 so as to pass through the center thereof.

측판(153)은 고정판(152)을 매개로 회전축(101)에 고정되게 결합되며, 측판(154)은 고정자지지부재(137)에 회전 가능하게 결합된다. 따라서, 회전축(101)의 회전하면 회전축(101)에 고정되게 결합되는 회전자(110)와 케이싱(150)은 동방향으로 회전하나 회전축(101)에 회전 가능하게 결합되는 고정자(130)는 회전축받침대 (102)에 고정되는 고정자지지부재(137)에 의해 회전되지 않는다.The side plate 153 is fixedly coupled to the rotation shaft 101 via the fixing plate 152, and the side plate 154 is rotatably coupled to the stator support member 137. Accordingly, when the rotating shaft 101 rotates, the rotor 110 and the casing 150 fixedly coupled to the rotating shaft 101 rotate in the same direction, but the stator 130 rotatably coupled to the rotating shaft 101 is the rotating shaft. It is not rotated by the stator support member 137 fixed to the pedestal 102.

또한, 케이싱(150)의 일단의 내벽에는 고정자지지부재(137)에 고정되게 결합되는 고정기어(138)와 맞물리도록 다수의 회전기어(155)가 설치된다. 회전기어(155)는 케이싱(150)이 회전축(101)과 함께 회전할 때 고정기어(138)를 따라 회전하며, 케이싱(150)의 측판(154)을 지지하여 케이싱(150)이 회전할 때 케이싱(150)의 떨림을 방지하는 역할을 한다.In addition, a plurality of rotary gears 155 are installed on the inner wall of one end of the casing 150 to be engaged with the fixed gear 138 fixedly coupled to the stator support member 137. The rotary gear 155 rotates along the fixed gear 138 when the casing 150 rotates together with the rotation shaft 101, and supports the side plate 154 of the casing 150 to rotate the casing 150. It serves to prevent the shaking of the casing 150.

회전기어(155)는 케이싱(150)의 떨림을 최소화할 수 있도록 안정된 3각구도나 4각구도로 배치되는 것이 바람직하며, 본 실시예에서는 4개의 회전기어(155)를 90도 간격으로 4각구도로 설치하였다.The rotary gear 155 is preferably disposed in a stable three-angle or four-angle sphere to minimize the shaking of the casing 150, in this embodiment four rotary gears 155 are installed in four angle spheres at 90 degree intervals. It was.

이하, 상술한 구성을 갖는 본 발명의 저속발전기(100)의 작용에 대하여 설명한다.Hereinafter, the operation of the low speed generator 100 of the present invention having the above-described configuration will be described.

회전축(101)에 외력이 인가되면, 회전축받침대(102)에 의해 지지되는 회전축(101)이 회전하게 된다.When an external force is applied to the rotating shaft 101, the rotating shaft 101 supported by the rotating shaft support 102 is rotated.

회전축(101)이 회전하면, 회전축(101)에 고정되게 결합된 회전자(110)와 케이싱(150)이 동방향으로 회전하게 된다. 이때, 케이싱(150)에 설치된 회전기어(155)들은 고정기어(138)에 맞물려 고정기어(138)의 외주를 따라 회전하게 되며, 고정자(138)는 회전축받침대(102)에 결합된 고정자지지부재(137)에 의해 정지된 상태를 유지하게 된다.When the rotating shaft 101 rotates, the rotor 110 and the casing 150 fixedly coupled to the rotating shaft 101 are rotated in the same direction. At this time, the rotary gears 155 installed in the casing 150 are engaged with the fixed gear 138 to rotate along the outer circumference of the fixed gear 138, the stator 138 is a stator support member coupled to the rotary shaft support 102 The stopped state is maintained by 137.

회전자(110)에 설치된 자석(111)과 고정자(130)에 설치된 도체(141)에 의해 형성되는 전력은 도체(141)에 권선된 코일(142)을 따라 격판(134)을 관통하여 격 판(154)와 고정자지지부재(137) 사이에 형성되는 공간을 통해 외부로 연결된 배선(143)을 통해 외부로 공급된다.Electric power generated by the magnet 111 installed in the rotor 110 and the conductor 141 installed in the stator 130 penetrates through the diaphragm 134 along the coil 142 wound on the conductor 141. It is supplied to the outside through the wiring 143 connected to the outside through the space formed between the 154 and the stator support member 137.

따라서, 회전자(110)와 케이싱(150)이 함께 동방향으로 회전하기 때문에 회전자(110)와 케이싱(150) 사이에 회전저항이 발생하지 않아 회전자(110)가 저속으로 회전하더라도 회전자(110)의 자석(111)과 고정자(130)의 도체(141) 사이에 상대속도가 크게 되어 원하는 기전력을 얻게 된다.Therefore, since the rotor 110 and the casing 150 rotate together in the same direction, there is no rotational resistance between the rotor 110 and the casing 150 so that the rotor 110 rotates at a low speed. Relative speed between the magnet 111 of 110 and the conductor 141 of the stator 130 is increased to obtain the desired electromotive force.

이상, 본 발명의 바람직한 실시예를 참조로 본 발명의 저속발전기에 대하여 설명하였지만, 본 발명의 사상을 벗어나지 않는 범위 내에서 수정, 변경 및 다양한 변형실시예가 가능함은 당업자에게 명백하다.Although the low speed generator of the present invention has been described above with reference to a preferred embodiment of the present invention, it will be apparent to those skilled in the art that modifications, changes, and various modifications can be made without departing from the spirit of the present invention.

본 발명의 저속발전기에 따르면, 자석이 부착되는 회전자와 철로 제조된 케이싱을 동시에 동방향으로 회전시켜 회전자에 걸리는 회전저항을 크게 줄임으로써 회전자의 자석과 고정자의 도체 간의 상대속도를 높일 수 있으며, 이로 인해 저속회전에서도 원하는 기전력을 얻을 수 있다.According to the low-speed generator of the present invention, by rotating the rotor and the casing made of iron at the same time in the same direction at the same time to greatly reduce the rotational resistance to the rotor can increase the relative speed between the magnet of the rotor and the conductor of the stator. As a result, the desired electromotive force can be obtained even at low rotation speed.

또한, 본 발명은 회전자와 고정자의 상대속도를 베어링, 회전기어, 고정기어 등 비교적 간단한 구성으로 높일 수 있어 저속발전기의 구조가 간단해지고 조립이 용이해지며 가격이 저렴해진다.In addition, the present invention can increase the relative speed of the rotor and the stator in a relatively simple configuration, such as bearings, rotary gears, fixed gears, so that the structure of the low-speed generator is simple, easy to assemble and low cost.

조력, 풍력 및 도로발전과 같이 저속회전력을 인가하는 경우 원하는 기전력을 얻을 수 없었다.When applying low-speed rotational power such as tidal, wind and road generation, the desired electromotive force could not be obtained.
