Rare earths are not required to manufacture free generators.


As for rare earths, China has 44 million tons, accounting for one-third of world reserves (120 million tons).
And Chinese rare earth companies occupy about 80% of the global market.


[Motor is parting with rare earth now, related patents are flooded]
2013.02.25

Hello.
I'm Hyung-sik Park, head of the Electricity Department at the Intellectual Property Office.

This briefing is about motor technology that does not use rare earth.

As you know well, isn't it becoming a global issue as the price of rare earth surges? For that reason, motor technology that does not use rare earth is also of interest. Recently, patent applications for off-rare earth motors have increased significantly.

According to the patent application statistics, the number of patent applications for motors that do not use rare earths increased from 6 in 2009 to 11 in 2010, and in 2011, the number of patent applications exceeded 26 in the first half alone, showing a rapid increase.

Rare earth refers to a metal element that is very rarely present in nature, and is widely used in motors to increase the magnetism of permanent magnets.

Typical rare earths for motors include neodymium and dysprosium, and it is known that about 1kg of rare earth is used for one electric vehicle motor.

I think it was due to China's export restrictions in 2008 that drove the free-earth wind into the motor sector. As Deng Xiaoping's words, "Oil in the Middle East and rare earth in China," represent, China accounts for 97% of the world's supply of rare earths, and its influence is absolute.

Before China's export restrictions, the neodymium price was 190,000 yuan per ton, but after the export restrictions, it surged more than 7 times to 1.47 million yuan per ton. In the end, it is interpreted that the motor industry, which felt a sense of crisis, hastened to develop rare earth alternative technologies, which led to the increase in patent applications.

Currently, the development of free-earth motor technology will proceed in two ways. One is the technology to improve the structure of a switched reluctance (SR) motor that does not require rare earths, and the other is a material development technology to replace rare earths with high-performance ferrite magnets.

For reference, the SR motor is a motor that generates rotational force by changing a magnetoresistive path without a permanent magnet. Since there is no magnet itself, it is a technology that does not require the use of rare earth at all. And ferrite refers to a magnetic ceramic containing iron oxide, and it is a technology that improves the magnetization characteristics of this material so that if it is used as a permanent magnet of a motor, the performance of the motor can be improved without using rare earth.

In the first half of 2011, applications related to SR motors accounted for 15 cases, and ferrite related technologies accounted for 11 cases, resulting in relatively many applications for SR motors. In particular, for SR motors, Samsung Electro-Mechanics has applied for the most with 11 applications, and in the ferrite field, 6 domestic companies and 4 Japanese companies have applied.

As we rely on imports for more than 90% of our rare earth usage, we believe we should pay more attention to the technology development of motors that do not use rare earth.

Since free-earth motors can influence the competitiveness of future food industries such as electric vehicles and wind power generators, competition for technology development in countries around the world for free-earth motors is expected to become more intense in the future, and patent applications will be steadily increased. Is expected.

This concludes the briefing. Thank you.

안녕하십니까? 특허청 전기과장 박형식입니다.

이번 브리핑 내용은 희토류를 사용하지 않는 모터기술에 관한 것입니다.

잘 아시다시피 희토류 가격이 급등하면서 세계적 이슈가 되고 있지 않습니까? 그 때문에 희토류를 사용하지 않는 모터기술도 관심의 대상인데, 최근 탈(脫)희토류 모터에 대한 특허출원이 크게 증가한 것으로 나타났습니다.

특허출원 통계를 보면, 희토류를 사용하지 않는 모터의 특허출원이 2009년 6건에서 2010년 11건으로 증가하더니, 2011년에는 상반기에만 26건을 돌파하여 급증세를 보이고 있습니다.

희토류는 자연계에 매우 드물게 존재하는 금속 원소를 가리키는 말로, 모터에서는 영구자석의 자성을 높이기 위해 많이 사용됩니다.

모터용 희토류는 대표적으로 네오디뮴과 디스프로슘을 들 수 있는데, 한 대의 전기자동차용 모터에는 약 1kg의 희토류가 사용되는 것으로 알려져 있습니다.

모터 분야에 탈희토류 바람을 몰고 온 것은 2008년 중국의 수출제한조치가 계기였다고 봅니다. '중동에는 석유, 중국에는 희토류'라는 덩샤오핑의 말이 대표하듯, 희토류 세계 공급량의 97%를 중국이 차지하고 있어 그 영향력은 절대적입니다.

중국의 수출제한 이전 네오디뮴 가격은 톤당 19만 위안이었으나, 수출제한 이후에는 톤당 147만 위안으로 7배 이상 급등하게 됩니다. 결국 위기의식을 느낀 모터업계가 서둘러서 희토류 대체기술 개발에 나선 것이 특허출원 증가로 이어졌다고 풀이됩니다.

현재 탈희토류 모터기술 개발은 두 갈래로 진행되고 되겠습니다. 하나는 희토류가 필요 없는 SR(Switched Reluctance)모터의 구조개량 기술이고, 다른 하나는 고특성 페라이트(Ferrite) 자석으로 희토류를 대체하려는 재료개발 기술입니다.

참고로 SR모터란 영구자석 없이 자기저항 경로를 변화시켜 회전력을 발생시키는 모터로, 자석 자체가 없기 때문에 희토류를 전혀 사용할 필요가 없는 기술입니다. 그리고 페라이트란 산화철을 포함한 자성체 세라믹을 말하는데, 이 재료의 자화특성을 개선하여 모터의 영구자석으로 사용하면 희토류를 사용하지 않고도 모터의 성능을 높일 수 있게 되는 기술입니다.

2011년 상반기 출원을 보면, SR모터 관련 기술이 15건, 페라이트 관련 기술이 11건을 차지하여 SR모터 관련 특허출원이 상대적으로 많았습니다. 특히, SR모터는 삼성전기가 11건으로 가장 많은 출원을 하였고, 페라이트 분야는 국내 기업이 6건, 일본 기업이 4건을 출원한 것으로 나타났습니다.

희토류 사용량의 90% 이상을 수입에 의존하는 우리로서는 희토류를 사용하지 않는 모터의 기술개발에 더욱더 관심을 가져야 될 것으로 생각됩니다.

탈희토류 모터는 미래먹거리산업인 전기자동차나 풍력발전기 등의 경쟁력을 좌우할 수 있다는 점에서, 앞으로 탈희토류 모터에 대한 세계 각국의 기술개발경쟁은 더욱 치열해질 것으로 보이며, 그로 인한 특허출원도 꾸준히 증가할 것으로 예상됩니다.

이상으로 브리핑을 마치겠습니다. 감사합니다.

희토류 대체물질을 사용한 자동차용 페라이트자석의 신뢰성향상 : Reliability Improvement of Automotive Ferrite Magnets with Replacement of Rare Earth Material
2014 year

모터나 교류발전기와 같이 전력을 생성하는 자동차부품은 페라이트 자석을 널리 사용하고 있다. 최근 어느 경쟁력있는 기업에서 생산한 자석에서 매우 작은 균열들이 발견되었다. 제조기업으로서는 자동차교류발전기용 이 자석이 고객에게 보내기 전에 고장이 없도록 해야야 하는 것이 당연하다. 해당 제품은 고객요구사항인 R90C90에서 160,000KM를 만족시켜야 한다(신뢰수준 90%로16만 KM 의 사용기간 동안 10%이상 고장나지 않도록 함). 따라서, 본 연구의 목적은 설계 및 제조프로세스를 개선하여 자석의 균열고장을 예방하는 것이다. 본 연구에서는 균열고장과 관련한 잠재적인 문제를 설계단계에서 제거할 수 있도록 고장물리(POF) 분석을 행하고, 선행적인 고장예방을 위하여 고장예방설계기술(DFFP)을 제안하였다. 제안된 신뢰성설계(DFR) 기술은 4단계로 구성되었다: (1)필드고장모드를 발견하기 위한 HALT; (2)잠재적인 제조결함 요인을 정확히 발견하기 위하여 응용 POF분석과 함께 공정 고장모드 및 영향분석(PFMEA): (3)결함요인에 대한 수정조치를 결정하기 위한 실험계획(DOE): (4) 선적전 최종 결함율과 BX 수명평가 방법의 4단계로 구성되었다. B10 수명향상을 위해 제조공정의 많은요인들에 대한 분석이 이루어졌으며, 결국 제안된 방법으로 자동차 페라이트 자석은 R90C90에서 160,000KM를 만족시켜 신뢰성향상이 이루어진 것을 알 수 있다.

Many automotive components for power generation, such as motors and alternators, have widely used ferrite magnets. Recently, some hairline cracks have been found on the magnet produced by a magnet manufacturer company. To stay as a competitive magnet manufacturer, the company pledges to ensure all magnets produced for alternators must be failure free before shipping to customers. Magnets should fulfill the customer requirement of R90C90 life of 160,000 km (less than 10 percent magnets will fail by the time of 160,000 km or 10 years). The objective of this study is to prevent crack failure of magnets through improving manufacturing processes. Design for Failure Prevention (DfFP) method was proposed for a proactive failure prevention of a design by utilizing Physics of Failure (PoF) analysis to design out potential problems. The proposed procedure of design for reliability has four stesps: (1) HALT to discover modes of field failures; (2) Process Failure Mode and Effect Analysis (PFMEA) with applied PoF analysis to pinpoint the potential manufacturing deficiency factors; (3) Design of Experiment (DoE) to determine corrective actions on the deficiency factors; (4) evaluation of final defect rate before shipping, and Bx, life (or MTBF). Based on the proposed method, the improvement of the automotive ferrite magnet reliability had been achieved. Several manufacturing parameter changes were implemented to address the improvement of the B10 life of the magnets.

Re: Magnetic Resonance Devices based on Don Smith Concepts
« Reply #543 on: October 19, 2016, 03:54:51 PM »

I think I have the primary mostly figured out, was able to bring the voltage in a large cap bank from 0 to 100v in less than a minute.  Not saying I have it all figured out but I have some things working correctly.  after wiring my primary like the video above (paying attention to the direction of the diodes) my spark gap works great and I get sparks across the secondary coil with a screwdriver when the primary is firing.  I have no ground on my primary circuit as of right now.

Can anyone give me a thorough explanation as to how I know if I have resonance in the primary coil or not?  I have made 4 different coils (and will probably have to make more to experiment with) but no way of knowing if they are running at their resonant freq or not.  I have an oscilloscope but have never used one before so I am not experienced in using a scope and don't want to fry it hooking it up wrong.

Two diodes, which all "gurus" hide with a thick layer of electrical tape
https://www.youtube.com/watch?v=vr6mQHwf_Zs&t=18s

With an accurate understanding of the Ruslan generator operating system, it is possible to know whether the resonance of the primary coil is working without an oscilloscope.
It's very easy.
What appears on the oscilloscope is the surge in current quantity.
This is because the oscilloscope is not the only way to measure the surge in current.
In addition to an ampere meter, you can also use a light fixture.
If you don't know that the lights are shining brightly even with both eyes, give up making a generator.
The biggest reason for misunderstanding the Ruslan generator is Tesla.
This misunderstanding comes from not understanding the generator operating system.

Members who have sincerely watched Ruslan's video in the meantime should know how to combine the method of two diode resonances.
If you don't understand this, it's good to give up.

Members who have not made the Ruslan Generator so far ask unnecessary questions.
Don't ask me, ask yourself.
How much you believed in Ruslan's video.

[Question]
What's different from the Andrian Guska generator?

Hi Color
I have worked with both of these connections. Andrian pushes at the same side during each cycle. It needs two diodes as you said because when one mosfet conducts, currents are induced at the other yoke's primary passing through the other mosfet (which is OFF) back to the battery through the body diode.
In my opinion both will work as the objective is to create a magnetic field across the grenade of a specific direction. In Adrian's way you can inject high frequency uppon both yoke's cycles. The other way of driving needs HF upon to one of the two cycles.

ps1. Yes i am a yoke maniac. I have an axe and a screwdriver in my car, and when i see an old tv in the trash, i extract the core in 3 minutes. I like opening tv's like a beans can.

I listen to you.
I have no objection.
From now on, I will understand Andrian as the creator of the free generator.
Thank you.

I have 8 TV-Yokes.
And Since I was young, disassembling home appliances including radios has been a hobby.
