본 고안은 로타리 트랜스포머에 관한 것으로, 특히 각 채널간의 자속의 상호 간섭을 감소시킬 수 있는 로타리 트랜스포머에 관한 것이다.The present invention relates to a rotary transformer, and more particularly to a rotary transformer that can reduce the mutual interference of the magnetic flux between each channel.
종래의 로타리 트랜스포머는 VCR의 경우 제1도에 도시된 바와 같이, 회전하는 로터(10)와 고정된 스테이터(20)으로 구성된다.The conventional rotary transformer is composed of a rotating rotor 10 and a fixed stator 20, as shown in FIG. 1 in the case of a VCR.
상기 로터(10)와 사테이터(20)은 각각 페라이트재질로 구성된 본체(11)(21)과 제 1 홈(12)(22)에 삽입된 제 1 채널 코일(13)(23)과 제 2 홈(14)(24)에 삽입되는 제 2 채널 코일(15)(25)으로 구성된다.The rotor 10 and the sitter 20 are each of the first channel coils 13 and 23 and the second channel 21 inserted into the main bodies 11 and 21 and the first grooves 12 and 22 made of ferrite material, respectively. It consists of second channel coils 15 and 25 inserted into the grooves 14 and 24.
로터(10)은 헤드(되시되지 않음)에 연결되고 회전축(1)에 결합되어 회전한다.The rotor 10 is connected to the head (not shown) and coupled to the rotating shaft 1 to rotate.
스테이터(20)는 OP AMP 에 연결되어 있다.The stator 20 is connected to the OP AMP.
제 1 채널 코일(13)(23) 및 제 2 채널 코일(15)(25)과 각각 서로 대향되어있고 일정권선비로 감겨져 있다.The first channel coils 13, 23 and the second channel coils 15, 25 are opposed to each other and are wound at a constant winding ratio.
1차적으로 헤드에서 유기된 전기적 신호가 회전하는 로터(10)에 전달되어, 로터(10)의 코일(13)(15)에 흐르는 전류는 제 2 도에 도시된 바와같이, 스테이터(20)의 본체(21)와 자기회로(A)를 구성하게 되고, 유도원리에 의해 스테이터(20)에는 로터(10)와 스테이터(20)의 각 채널의 코일 권선비에 비례하는 양의 전류신호가 흐르게 된다.The electrical signal primarily induced in the head is transmitted to the rotating rotor 10 so that the current flowing in the coils 13 and 15 of the rotor 10 is transferred to the stator 20 as shown in FIG. The main body 21 and the magnetic circuit A are configured, and due to the induction principle, a positive current signal flows in the stator 20 in proportion to the coil turns ratio of each channel of the rotor 10 and the stator 20.
이렇게 유도된 스테이터(20)의 전류신호는 OP AMP에서 증폭되어 전기회로에 유입되게 된다.The current signal of the stator 20 thus induced is amplified in the OP AMP and introduced into the electric circuit.
이와같이 로터(10)와 스테이터(20)간에는 자속에 의해 전기신호가가 전달되기 때문에 이웃하는 채널 사이에 자기적 간섭현상에 의해 크로스토크(Cross tallk)가 발생하고 입력전류의 감쇠(삽입손실)현상이 나타난다.In this way, since electric signals are transmitted between the rotor 10 and the stator 20 by magnetic flux, crosstalk occurs due to magnetic interference between neighboring channels and attenuation of the input current (insertion loss) occurs. Appears.
한편 크로스토크는 이웃채널간의 결합계수 KCT에 비례하고 KCT는 본체의 기하학적인자에 의해서 결정된다.On the other hand, the crosstalk is proportional to the coupling coefficient K CT between neighboring channels, and K CT is determined by the geometric factors of the body.
본 고안은, 이러한 종래기술의 문제점을 해결하기 위한 것으로 각 채널간에 폐쇄된 자로를 형성하여 각 채널간의 자기적 간섭현상에 의한 크로스 토크를 제거할 수 있는 로타리 트랜스포머의 제공을 목적으로 한다.The present invention aims to provide a rotary transformer capable of eliminating crosstalk caused by magnetic interference between channels by forming a closed magnetic path between each channel to solve the problems of the prior art.
상기 목적을 달성하기 위하여, 본 고안의 로타리 트랜스포머는, 본체를 비자성재료를 형성하고, 코일이 삽입되는 홈둘레에 자성막을 형성하여 자성막사이에만 폐쇄자로를 형성하는 것이다.In order to achieve the above object, in the rotary transformer of the present invention, a nonmagnetic material is formed in the main body, and a magnetic film is formed in the groove circumference where the coil is inserted to form a closed circuit only between the magnetic films.
이하, 첨부도면에 도시된 실시예에 의거하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail based on the embodiment shown in the accompanying drawings.
제3도는 본 고안에 따른 로타리 트랜스포머를 나타낸것으로, 회전하는 로터(10)와 고정된 스테이커(20)로 구성되어 있다.Figure 3 shows a rotary transformer according to the present invention, it is composed of a rotating rotor 10 and a fixed staker 20.
상기 로터(10) 및 스테이터(20)의 각 본체(11)(12)는 비자성 제료인 Ca TiO3로 구성된다.Each of the main bodies 11 and 12 of the rotor 10 and the stator 20 is made of Ca TiO 3 , which is a nonmagnetic material.
또한 로터(10)및 스테이터(20)의 각 제1 홈(12)(22) 및 제 2 홈(14)(24)에는 제 1 채널코일(13)(22) 및 제 2 채널코일(15)(25)이 각각 삽입되어 있고, 상기 제 1 홈(12)(22) 및 제 2 홈(14)(24)의 둘레에는 Fe, Si, Al로 구성된 자성합금인 센다스트막(17)(27) 및 (18)(28)이 각각 형성되어 있다.In addition, each of the first grooves 12, 22 and the second grooves 14, 24 of the rotor 10 and the stator 20 has a first channel coil 13, 22, and a second channel coil 15. 25 are inserted, respectively, and around the first grooves 12, 22 and the second grooves 14, 24 are sendast films 17 and 27 which are magnetic alloys composed of Fe, Si, and Al. And (18) and (28) are formed, respectively.
상기 구성의 작용을 설명한다.The operation of the above configuration will be described.
헤드(도시되지 않음)에서 로터(10)에 전달된 전기신호는, 제3도에 도시된 바와같이, 로터(10)와 스테이터(20)사이에서 자기회로(B)를 형성하여 유동원리에 의해 스테이터(20)에 전달된다.The electrical signal transmitted from the head (not shown) to the rotor 10, as shown in FIG. 3, forms a magnetic circuit (B) between the rotor 10 and the stator 20 and is driven by the flow principle. It is delivered to the stator 20.
이때 형성되는 자기회로(B)는, 로터(10)와 스테이터(20)의 본체(11)(21)가 비자성재료로 형성되어 있어, 자성합금막(17)(27) 및 (18)(28)간에만 각각 폐쇄되어 이루어진다.In the magnetic circuit B formed at this time, the main body 11 and 21 of the rotor 10 and the stator 20 are formed of a nonmagnetic material, and the magnetic alloy films 17, 27 and 18 ( 28) are only closed each time.
따라서 이웃채널간의 결합계수(KCT)가 무시될 정도로 작아지고, 상기 계수에 비례하는 크로스토크도, 솟트링을 사용하지않고 저감시킬 수 있다.Therefore, the coupling coefficient K CT between neighboring channels becomes small enough to be ignored, and crosstalk proportional to the coefficient can be reduced without using the ring.
이상과 같이, 본 고안의 로타리 트랜스포머에 따르면, 본체를 비자성재료로 구성하고, 코일이 삽입되는 홈둘레에 자성합금막을 형성하여 이웃채널간에 폐쇄되는 자로를 형성할 수 있어 자속의 상호간섭에 따른 크로스토크를 저감시킬 수 있다.As described above, according to the rotary transformer of the present invention, the main body is made of a nonmagnetic material, and a magnetic alloy film is formed around the groove into which the coil is inserted, thereby forming a magnetic path that is closed between neighboring channels. Crosstalk can be reduced.
