According to media reports, rare earth permanent magnet coreless motor will be included as a key technology in the upcoming "energy saving and environmental protection industry development plan".

Investment points: NdFeB magnetic material is the king of permanent magnet.

Compared with the traditional motor, rare earth permanent magnet coreless motor has the characteristics of high efficiency and energy saving, light weight, small volume, good speed control and strong reliability, which can be widely used in wind power generation, electric vehicles, industrial motors, household motors and other fields.

In terms of industrial energy-saving motors, the power consumption of fans, pumps, compressors and other general equipment in China's key energy consuming industries accounts for more than 40%, and the annual power consumption exceeds 500 billion watt hours. According to conservative estimation, the average operation efficiency of the system driven by rare earth permanent magnet coreless motor can be increased by 20% - 40%, with energy saving potential of 100-200 billion kwh.

At present, the market scale of wind power generation equipment in China is nearly 100 billion yuan, and the market demand of rare earth permanent magnet coreless wind turbine is huge. Among all kinds of wind turbine units equipped at present, permanent magnet wind turbine has become the first choice for wind turbine because of its high efficiency, small volume, high reliability, simple structure and other characteristics. Using rare earth permanent magnet material can improve the efficiency of the generator to more than 85%. At the same time, using permanent magnet generator can also achieve the direct coupling between wind turbine and generator, eliminating the gearbox, so as to improve the efficiency High reliability, laugh at system noise, reduce maintenance costs. In 2008, China added more than 5130 new wind turbines, with an installed capacity of 6.3 million kilowatts. The total installed capacity doubled for the fourth year in a row, and the total installed capacity has reached 12.21 million kilowatts. It is estimated that China's wind power is expected to achieve an installed capacity of 100 million kilowatts by 2015. According to the calculation of 0.6-1.5 tons of NdFeB required for each 1MW permanent magnet wind turbine, about 60000-150000 tons of NdFeB will be consumed, which provides a broad space for the future application of NdFeB permanent magnet materials.

New energy vehicles will be a strategic emerging industry during the 12th Five Year Plan period. According to the latest planning, by 2015, China will have 1 million new energy vehicles in the promotion and application, the state will invest 100 billion in basic R & D and infrastructure construction, and the national team of new energy vehicles will invest 100 billion in enterprise level R & D. Permanent magnet synchronous motor (PMSM) will be widely used in electric vehicles in the future because of its high energy efficiency, small size and light weight.

At present, about 98% of air conditioners in Japan, Europe and the United States are frequency conversion air conditioners, but there are few applications in China. Frequency conversion air conditioning is a trend in the future because of its comfort and energy saving. Rare earth permanent magnet motors will be widely used in air conditioners, air compressors, fans and other household appliances. Due to the huge market of home appliances in China, the development of frequency conversion home appliances will open up a new application field for NdFeB permanent magnet.

With the rapid development of new application fields, it is estimated that the global growth rate of NdFeB industry will remain 15% in the next five years, while China is expected to maintain a growth rate of more than 20%.

From the perspective of raw material supply, the main raw materials for the production of NdFeB are praseodymium, neodymium and dysprosium in rare earth metals. With the strengthening of China's control over rare earth resources and the completion of enterprise resource integration, the supply of rare earth metal resources will become scarce and the price will rise, which will exert certain pressure on the raw material cost of NdFeB; on the other hand, China's restrictions on the export of rare earth raw materials will also force foreign companies to import more NdFeB finished products, and the technology of domestic enterprises will gradually mature, with the development of high-end NdFeB magnets Production has entered the stage of industrialization, and products are being replaced by imports and exported to the markets of developed countries
