Small and Medium-Sized China Rare Earth Magnet Enterprise Research: MQ Magnetic Powder Patents Expiry Bringing Cost of Bonded Neodymium Magnets, More Space to Decline
---Bonded NdFeB: MQ-magnetic powder patent monopoly leads to low growth of industry. In the last ten years, bonded permanent magnet developed lowly, the production of it less than one over ten of sintered neodymium iron boron. There are 2 major reasons: 1) comparing with sintered magnet, the magnetic properties and mechanical strength of bonded NdFeB rare earth magnet is weak, and the scope of application is narrow. Bonded magnet is mainly applied for HDD and spindle motors of CO-ROM divers as well as vibrations and other consumer electronics fields and automobile micro motors.With the introduction of new technology and improvement of craft, we believe, the magnetic property and mechanical performance, will continuously upgrade and the range of application in field of consumer electronics as well as automobile will expand. (2) Magnequench Co. Ltd, monopolizing the component of magnet raw materials and product patent, doesn’t grant authorization to other companies. As a result of monophonic supply, the price of magnetic powder is high.
---The cost of bonded neodymium permanent magnet is expected to decline with the expiry of MQ magnet powder patent. As a monopolist, Magnequench Co. Ltd occupies 80% market shares. Its patent of component will be expired in July 2014. The price of magnetic powder is going to decline. (1) In recent several years, our country has a capacity of producing a certain scale of magnetic powder driving by domestic demand. (Domestic market is not limited by patent).According to the research of our company, domestic magnetic powder is 30%-40% cheaper than the MQ powder. If adopted our domestic magnetic powder, the cost of Bonded NdFeB would cut down 20%-30%.
---Declination of bonded neodymium rare earth magnet will bring expansion of industry. Nowadays, the scale of production of bonded NdFeB is up to 100,000 tons but, ferrite permanent magnets can reach millions of tons. You can imagine that how huge the alternative space is. The specific field of Bonded NdFeB Substituting Ferrite and Sintered magnet: with the reduction of cost and requirements of energy conservation and environmental protection, lightweight and miniaturization, bonded magnets, taking place of ferrite, can be applied to high-end field, e.g. Automotive micro-motor. Bonded neodymium property improves its property, especially with anisotropic bonded magnet doubling its performance; whose declining cost can eliminates the price disadvantage, enabling bonded magnet to infiltrate into fields with low magnet property, such as, VCM and electronic tools.

Rare Earth Permanent Magnet Synchronous Generator
The Best Choice of Drive Motor for Electric Passenger Cars
(8/17/2014, Beijing, China) According to data compiled by University of California, Davis, by the end of 2013, most of global mainstream new energy electric passenger vehicle models, except Tesla Model S ranking the third place of market share (9.97%), has adopted permanent magnet synchronous motor vehicles. It plays an important role in electro-mobile field. As a result of adoption of high performance rare-earth magnets, it operates more steadily, reliably and has longer service life. Also, they have higher power density and smaller volume as well as higher efficiency.
China has notable superiority in the area of rare earth permanent magnet motors for it has the world's largest rare earth reserves. Also, after more than ten years of development, China has accumulated a number of very powerful rare earth magnets manufacturers.
Professor ShenJianxin, a member of Institution of Engineering and technology of Britain (IET), an authoritative engineering and technology organization, believes that China has built a complete industrial chain and industrial ecosystem in respect of rare earth permanent magnet motor. Also, comparing with Europe and America, China has evident advantages in raw-material cost and production cost, with its technical index taking rank with developed countries. Currently, rare earth magnet synchronous motors developed and produced by China has been supplied to many famous auto enterprises including Fisker in America and Chery, Wanxiang, Geely, Zotye, Haima and BYD in China. “The whole world is now developing green economy, including promotion of new energy vehicles and electric automobile. In this respect, China can fully meet the market demands.” said Professor Shen.
The application of neodymium permanent magnet motor has a very bright future. It is introduced that the total amount of electrical energy consumed by motors accounts for 60% of total power grid electricity. So, highly effective motors have great economic value, environmental value and social value. Moreover, such motors are one of main technologies to make motors efficient. Professor Shen thinks that it is the first choice for high-end motor drive system in the future. It can be widely applied to transportation and delivery, high-end processing equipment, robot and air-foil fan, pump as well as other white household appliances. China should continually improve the performance of rare earth permanent magnetic materials and electric material, constantly develop technology of electric machine design and drive control to meet more requirements of neodymium magnet motor market.

Permanent Magnet VS Electromagnet
Permanent Magnet Manufacturer China Rare Earth Magnet Limited
Both Permanent Magnets and electromagnets can create different forms of magnetic fields. When choosing the magnetic circuit, you should first consider the purpose of this magnet. Under some circumstances of inconvenient power supply, usual power cut and unnecessary adjustment of magnet force，permanent magnet is preferred. However, when there is need for adjusting magnet force or using remote control, electromagnet is better. Magnets only can be used in the initially scheduled way. If you use wrong type of magnets for some special purposes, it can cause extreme or even fatal danger.
Many machining operations are processing on the heavy block materials during which permanent magnets are necessary. Many users of machinery factories think that the biggest advantage of these magnets is in no need of electrical connection.
Permanent magnet features lifting power of 330~10,000 pounds and can connect or disconnect the magnetic circuit only by rotating a hand shank. Magnet usually has security lock to make sure the magnet will not accidentally disconnect when being lifted. Magnet set can be used for purpose of relatively heavy and long load that a single magnet can't cope with.
Besides, most of the time, the parts we prepare for machining are very thin (0.25 inches or thinner) and we need to extract it from a pile of similar parts. Permanent magnet is not suitable for the work of extracting only one part from a pile of parts. Permanent magnet is dependable when used correctly, but its magnetic force can not be changed. In this respect, electromagnet, with variable voltage control device, enables operators to control magnet field strength as well as pick up one component from piles of parts. As the most economical magnet per unit lifting capacity, self-contained electromagnet can extend its lifting ability to 10500 pounds.
