China's rare earth permanent magnet motor development and huge industrial capacity

    NdFeB magnets are currently found in the commercialization of the highest performance magnets, known as Magneto. Its chemical formula is Nd2Fe14B, the permanent magnet is an artificial, so far the strongest permanent magnets having a magnetic force.
    NdFeB magnets can be divided into two kinds of sintered NdFeB and Bonded NdFeB. Injection molding is actually bonded, and sintering is heated to high temperatures by vacuum molding!
    NdFeB magnets as the third generation rare earth permanent magnet materials with high performance, which are widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the development of information technology as the representative of the knowledge-based economy , to rare earth permanent magnet NdFeB industry and other functional materials continue to bring new uses, which brings a broader market prospects for the NdFeB industry.
    NdFeB magnets are tetragonal crystal made of neodymium, iron and boron formation. In 1982, Sumitomo Special Metals Sagawa real discovery neodymium magnets. This magnetic energy product greater than samarium cobalt magnets, then the world's largest energy product material. Later, Sumitomo Special Metals successful development of powder metallurgy, GM's successful development Churning smelting method, capable of producing NdFeB magnets. This magnet is now the strongest magnetic permanent magnet, rare earth magnet is the most commonly used.
    Its hard, stable performance, good price, so its application is extremely broad. But because of its chemical activity is very strong, it must deal with its surface coating. Everyday electronic products, such as hard disk, mobile phones, headsets, etc., there exists neodymium magnets.
    As one of the rare earth material NdFeB material is the most important application areas, is one of modern electronic information industry to support important basic materials, and people's lives. With the rapid development and popularization of energy-efficient car computers, mobile phones, car phones and other communications equipment, the world demand for high-performance rare earth permanent magnet materials is growing rapidly. Neodymium magnets as the permanent inverter compressor "heart" is essential. In the first decade of this century, China has completed the transformation from a permanent magnet material production country's largest producer of high-efficiency motors. China's production of rare earth permanent magnet motor compressor lot of equipment, began to export to European markets. China's development and huge industrial capacity of rare earth permanent magnet motor, frequency conversion air compressor to lead the world trend.
