본 고안은 회전하는 물체에 전원을 공급하기 위한 장치에 관한 것으로, 특히 자속을 이용한 회전설비의 무선전원공급장치에 관한 것이다.The present invention relates to a device for supplying power to a rotating object, and more particularly to a wireless power supply of a rotating installation using the magnetic flux.

회전체로의 전력공급은 크게 비접촉식과 접촉식으로 구분된다.Power supply to the rotor is divided into contactless and contact.

비 접촉식 전력공급장치의 첫번째 예는 회전체내에 건전지를 삽입하여 전력을 공급하는 방법이 있다.A first example of a contactless power supply is a method of supplying power by inserting a battery into a rotating body.

이는 건전지의 수명이 다할 경우 회전설비를 정지시켜 건전지를 교체해야 하므로 지속적인 전력공급을 할 수 없으며, 건전지 설치기간동안 일시적으로 전력공급이 차단될 수 밖에 없다.When the battery reaches the end of its life, the rotating equipment must be stopped and the battery must be replaced, so the power supply can not be sustained, and the power supply is temporarily cut off during the battery installation.

둘째로, 회전체에 광 수신소자를 취부하고 정지부에서 빛을 쪼여서 전력을 공급하는 방법이 있다.Secondly, there is a method of supplying power by attaching a light receiving element to the rotating body and extracting light from the stop.

이는 사용하는 곳의 환경이 청결해야 지속적으로 전력을 공급할 수 있으며 공급가능 전력에 한계가 따르게 된다.This means that the environment in which it is used must be clean so that it can be supplied continuously and there is a limit to the power available.

셋째로 회전체에 전압유도코일을 취부하고 정지부에 영구자석을 설치하여 ,회전체가 회전할 경우 영구자석의 고정 자속(Magnetic Flux)에 의해서 전압유도코일에 유기되는 전압으로 전력을 공급하는 방법이 있다.Third, by installing a voltage induction coil on the rotor and installing a permanent magnet on the stop, and supplying power to the voltage induced in the voltage induction coil by the magnetic flux of the permanent magnet when the rotor rotates There is this.

이는 유기 전압이 회전부의 회전속도에 따라서 그의 출력 전압의 크기가 변하고 회전부가 정지할 경우 전력을 공급하지 못하게 되는 단점이 있다.This has the disadvantage that the induced voltage does not supply power when the magnitude of the output voltage thereof changes according to the rotational speed of the rotating part and the rotating part stops.

한편, 접촉식에 의한 전력공급장치의 예를 들면, 직류모터의 전력공급과 같이 회전부에 슬립링을 설치하고 정지부에 브러쉬를 설치하여 전력을 공급하는 방법으로 , 정기적으로 실립링과 브러쉬를 교체하여야 하며 먼지와 기름이 많은 산업현장에 사용하는데 불편이 있다.On the other hand, for example, a contact type power supply device, such as a DC motor power supply in which a slip ring is installed on the rotating part and a brush is installed on the stop part to supply electric power. It is inconvenient to use in industrial sites with a lot of dust and oil.

본 고안의 목적은 회전하는 설비내에서 요구되는 전력을 공급함에 있어 위에 열거된 문제를 해결하기 위해서는 회전부와 정지부에 각각의 유도코일을 설치하여 회전부에 무선 비접촉으로 요구되는 전력을 공급할 수 있게되는 자속을 이용한 회전설비의 무선전원 공급장치를 제공하는데 있다.The purpose of the present invention is to provide the power required in the rotating equipment to solve the problems listed above to install the respective induction coil to the rotating part and the stop to be able to supply the power required by wireless non-contact to the rotating part The present invention provides a wireless power supply device for a rotating facility using magnetic flux.

첨부된 도면을 기초로 하여 본 고안을 설명하면 다음과 같다.Referring to the present invention based on the accompanying drawings as follows.

제1도와 제2도에서 참조되는 바와 같이 회전체에 전원을 공급하는 장치는 회전설비인 회전부(1)와 회전부의 신호처리 장치에서 요구되는 전압을 만드는 정류부(2), 그리고 회전부에 연결되어 회전부와 같이 회전하는 회전부 유도코일(3), 정지부에 고정되어 회전부 유도코일에 연결되는 자속을 발생시키는 정지부 유도코일(4), 정지부 유도코일에 자속이 발생할 수 있도록 교류전압을 만들어 주는 교류전압 발생기(5)로 구성된다.As shown in FIG. 1 and FIG. 2, a device for supplying power to a rotating body includes a rotating part 1, which is a rotating device, a rectifying part 2 for generating a voltage required by the signal processing device of the rotating part, and a rotating part connected to the rotating part. Rotating part induction coil (3) to rotate as shown, stop part induction coil (4) is fixed to the stop to generate the magnetic flux connected to the induction coil, AC alternating current to make the magnetic flux to the stop induction coil It consists of a voltage generator 5.

회전부 유도코일(3)과 정지부 유도코일(4)과의 전기적인 연결은 정지부 유도코일(4)에 발생하는 자속에 의해서 이루어지므로 회전부와 정지부사이에 전선연결을 하지 않고도 비접촉식으로 전력을 공급할 수 있도록 한다.The electrical connection between the rotating part induction coil 3 and the stop induction coil 4 is made by the magnetic flux generated in the stop induction coil 4 so that electric power can be supplied in a non-contact manner without a wire connection between the rotating part and the stop part. To help.

이와 같이 구성된 본 고안을 제3도를 기초로 하여 동작 및 효과를 설명하면 다음과 같다.Referring to the present invention configured as described above and the operation and effects on the basis of Figure 3 as follows.

먼저, 교류전압 발생기(5)에서 전압의 크기가 일정하고 주파수가 수십 KHz인 교류전압을 발생시켜 정지부 유도코일(4)양단에 인가한다.First, the AC voltage generator 5 generates an AC voltage having a constant voltage and a frequency of several tens of KHz, and applies it across the stop induction coil 4.

이 인가된 전압은 플래밍의 왼손 법칙에 의해서 정지부 유도코일에 교번 자속(Alrernative Flux)을 발생시킨다.This applied voltage generates alternating flux in the stop induction coil by the flaming left hand law.

이때 발생되는 교번자속의 량은 인가되는 교류전압의 크기와 정지부 유도코일(4)의 코일 회전수에 비례하여 결정된다.The amount of alternating magnetic flux generated at this time is determined in proportion to the magnitude of the applied alternating voltage and the coil rotation speed of the stop induction coil 4.

이렇게 발생된 교번자속은 공기를 통과하여 회전부 유도코일(3)을 포함하는 페루우프를 형성하고, 공기를 통과한 교번 자속은 회전부 유도코일(3)을 교번적으로 쇄교한다.The alternating magnetic flux thus generated passes through air to form a Peruvian hoop including the rotating part induction coil 3, and the alternating magnetic flux passing through the air alternates between the rotating part induction coils 3.

이 쇄교된 교번자속은 트랜스포머와 같은 원리로 회전부 유도코일(3)에 교류전압 발생기와 같은 형태의 전압을 발생시킨다.This alternating alternating flux generates a voltage in the form of an AC voltage generator in the rotor induction coil 3 on the same principle as the transformer.

발생된 교류전압의 크기는 회전부 유도코일(3)의 감긴 횟수에 비례하고, 정지부유도코일(4)의 감긴횟수에 반비례하므로, 회전부 유도코일(3)에 발생하는 전압은 회전부 유도코일(3)과 정지부 유도코일(4)의 코일비, 그리고 교류전압 발생기(5)의 전압 크기로 결정된다.Since the magnitude of the generated AC voltage is proportional to the number of turns of the induction coil 3 of the rotor and inversely proportional to the number of turns of the stop induction coil 4, the voltage generated in the rotor induction coil 3 is the induction coil 3 of the rotor. ), The coil ratio of the stop induction coil 4 and the voltage magnitude of the AC voltage generator 5.

회전부 유도코일에 유기된 전압은 교류전압이므로 이 전압을 직접 사용할 수도 있고, 회전부의 부하(6)에서 요구되는 전압이 직류전압일 경우 교류전압을 직류전압으로 변환하는 정류부(2)를 통해 직류전압을 회전부(91) 신호처리기, 즉 부하(6)에 공급한다.Since the voltage induced in the rotating part induction coil is an AC voltage, this voltage may be directly used. When the voltage required by the load 6 of the rotating part is a DC voltage, the DC voltage is converted through the rectifying unit 2 to convert the AC voltage into a DC voltage. Is supplied to the rotating unit 91 signal processor, that is, the load 6.

이러한 본 고안은 회전하는 설비에서 요구되는 전력을 비접촉식인 부선으로 공급하는 장치로서, 그 장점은 회전부의 회전속도와 무관하게 일정한 전력을 공급할 수 있으며, 자속을 이용하여 회전부와 정지부를 전자기적으로 연결하므로, 먼지나 기름등으로 오염된 산업체 설비에서도 회전체내의 측정설비등의 부하에 지속적인 전력공급이 가능하게 되는 특징으로 가진다.The present invention is a device for supplying the power required in the rotating equipment to the non-contact barge, the advantage is that it can supply a constant power irrespective of the rotational speed of the rotating unit, using the magnetic flux to connect the rotating unit and the stop electromagnetically Therefore, even in industrial equipment contaminated with dust or oil, it is possible to continuously supply power to the load of the measuring equipment in the rotating body.
