large capacity of rare earth permanent magnet synchronous generator for aviation power supply

At home and abroad has developed 500 ~ 2000 VA uav with rare earth permanent magnet synchronous generator series, 45 ~ 150 KVA onboard power supply system with large capacity of rare earth permanent magnet generator. In order to meet the demand of aviation power supply quality of the increasingly high standards, an adaptive compound excitation rare earth permanent magnet generator is attracting the attention of both at home and abroad. The generator is a blend of rare earth permanent magnet and the characteristics of electrical excitation generator has high efficiency and good capability of voltage adjustment.

China accounts for about 23% of the world’s total reserves of rare earth resources to undertake the supply of more than 90% of the world market

Published in 2012 by the Chinese government white paper on “China’s rare earth situation and policy”, points out that China accounts for about 23% of the world’s total reserves of rare earth resources to undertake the supply of more than 90% of the world market. At the same time, with abundant rare earth resources of the United States and other western countries, no exploitation of rare earth for themselves, but a large number of imports of rare earths from China. For this situation, many overseas analysts pointed out that it is not reasonable, sustainable market arrangement, need to adjust and change.

global new energy vehicles development to bring growth of permanent magnet ndfeb industry

New energy car booster permanent magnet industry is growing rapidly. Ndfeb demand accounted for about 30% of new energy automobile production under the policy to promote there will be a process of rapid growth. Despite its scale, that need to be further mature technology, but in the global new energy vehicles under the situation of rapid development, rapid growth of domestic new energy vehicles will enter, and long-term investment value, the future demand for ndfeb will exceed 30%.

Freescale, the semiconductor manufacturers in the United States, announced a new wireless charging solutions which make the users step closer to wireless Internet of the future. Starbucks has actively layout wireless charging in silicon valley and Beijing. These will drive the magnetic material consumption, and rare earth is the important material in the manufacture of the magnets.

According to foreign media reported on December 9, 2014 Freescale semiconductor manufacturers in the United States announced a new wireless charging solutions, the product of 15 watts, can provide mobile phone charge three times the power, products, easy to carry, and can be layout to all aspects of people’s life, such as airplane seat, a coffee shop and the dining room table and so on. The product is expected to go on sale in early 2015. The solution for dressing equipment, tablet, big screen smartphones and portable industrial and medical equipment and other large super fast wireless charging of mobile devices, paving the way for the user to step closer to the wireless Internet of the future.

In 2013, the first two stores in silicon valley has brought the wireless charging for the user. Users at the time of drinking coffee, as long as their phones in preset good wireless charger on the table, can support wireless charging of mobile phone recharged for himself. By mid – 2013, starbucks, McDonald’s and companies such as AT&T in America’s big airport, coffee shop, shopping center, and the stadium has deployed more than 1500 charging point. In Europe, PowerKiss already in airport, hotel and coffee shop supervision and installed more than 1000 charging point. Starbucks also has 200 stores in San Francisco bay area set up wireless charging stations. At the Beijing capital airport now in terminal 3 C, and D all are equipped with wireless charging pile near the gate, will be one by one.

In 2015, from the first generation of inductance to the second generation of magnetic resonance (NMR) technology will promote the development of wireless charging into the mainstream products, coffee shops, airports, restaurants and movie theaters and other places of wireless charging stations will be even more popular. With perfect ecological system gradually established, will further stimulate consumer demand for wireless charging, and is expected in the next year there will be a formal commercial wireless charging product.

So what is the working principle of magnetic resonance (NMR) wireless charging technology? According to introducion, it is to use the principle of nuclear magnetic induction charging equipment, similar to the transformer, the sending and receiving end each have a coil, the sender coil connection cable power signal, the receiver coil induction send the electromagnetic signal to generate an electric current to electric equipment. Wireless charging products mainly have three key components, including the control circuit board, induction coil, magnetic materials. In the process, magnetic materials play an important role. According to TDK wireless charging product related technical chief introduction, Permanent magnetic material itself and the process layout has a very important influence for the efficiency of wireless charging. In China, some of the biggest magnetic material manufacturers have been making magnets for wireless charing products.
