Application, a large number of high-performance NdFeB permanent magnet material is through the use of the motor to play a role, and the use of permanent magnet material motor is often referred to as permanent magnet motor. Permanent magnet motor is divided into ferrite excitation motor and rare earth permanent magnet motor. The motor is a magnetic field for the medium for mechanical energy and electrical energy conversion of electromagnetic devices.

There are two methods for establishing an air gap magnetic field necessary for electromechanical energy conversion in a motor. There are two ways to generate current in the motor windings, requiring both a dedicated winding and a corresponding device to continuously provide energy to maintain current flow. Known as the electric field motor, such as ordinary DC motor and synchronous motor; permanent magnet to produce magnetic field, can simplify the motor structure, but also save energy, which is permanent magnet motor. The application of permanent magnet motor is extremely widely distributed in aviation, aerospace, defense, equipment manufacturing, industrial and agricultural production and daily life in all areas: its capacity from large to small, has reached megawatts, the application of more and more wide; More and more important, from military to civilian, from special to ordinary areas, not only in the micro motor dominance, but also in the electric propulsion system also shows a strong vitality. Compared with the traditional electric field motor, rare earth permanent magnet motor has the advantages of simple structure, reliable operation, small volume, light weight, low loss, high efficiency, flexible shape and size of motor. Compared with the rare earth permanent magnet motor produced by the traditional NdFeB permanent magnet material, the new rare earth permanent magnet motor with high performance NdFeB permanent magnet material is smaller, the loss is lower and the efficiency is significantly higher than that of the traditional rare earth permanent magnet motor The

Rare earth permanent magnet motor is a highly efficient energy-saving products, the average energy-saving rate of up to 10% or more, the application of high-performance NdFeB permanent magnet material rare earth permanent magnet motor energy saving rate can be as high as 15% to 20%. In the wind turbines, compressors and other needs of the Promise frequency control of the occasion, permanent magnet frequency control power saving rate of up to 30% or more. International motor energy level is the advanced level of the fan itself is generally more than 80% efficiency, the system operating efficiency of about 85%. At present, China's domestic equipment ontology design efficiency of 70%, the system operating efficiency of less than 30%, power waste is very serious. According to the International Energy Agency (IEA) July 2006 work report, by improving the motor efficiency combined with frequency control can save about 7% of the electricity, which is roughly 1/4 to 1/3 is to improve the efficiency of the motor to get. In order to coordinate national energy efficiency grading standards, in 2006, the International Electrotechnical Commission (IEC) developed an energy efficiency standard IEC60034-30. The standard will be the general purpose of the motor efficiency level is divided into IE1, IE2, IE3, IE4 four, which IE1 standard efficiency, equivalent to China's current production of your series of induction motor efficiency level; IE2 for high efficiency, The average efficiency increased by 2.75%, the average loss of about 20% loss; IE3 for the ultra-high efficiency, efficiency and then increased by 1.5% to 2%, the average loss and then reduced by 15%, only the United States is expected in 2010 to reach IE3 energy level, IE4 for ultra-high efficiency, loss is expected to drop about 20%. On the whole, the application of high-performance NdFeB permanent magnet material rare earth permanent magnet motor is easy to achieve high efficiency, that is, to IE2 level efficiency value.

Rare earth permanent magnet motor is high power (high speed, high torque), high functionality and miniaturization direction, and constantly expand the new motor varieties and applications. At present, China's high-performance NdFeB permanent magnet materials, the main downstream industry is divided into two categories, the traditional downstream industries, including VCM motor and personal consumer electronics products; new energy and energy saving and environmental protection industries, including energy-saving wind power generation equipment, energy-saving elevator Lead machine manufacturing, energy saving and environmental protection air conditioning (inverter air conditioner), EPS and hybrid vehicles. It is noteworthy that energy-saving environmental protection air-conditioning and hybrid cars currently on the demand for high-performance NdFeB permanent magnet material is mainly through the procurement of Japan's production of high-performance NdFeB permanent magnet material and meet the current not yet selected China's high Performance NdFeB permanent magnet material.

In the next few years, China's energy-saving wind power generation equipment industry, energy-saving elevator traction machine manufacturing industry, hybrid vehicles and EPS manufacturing industry will be with the country's new energy, energy-saving emission reduction efforts to continuously improve the rapid development, The demand for high-performance NdFeB permanent magnet materials will grow rapidly; and VCM motor and personal consumer electronics products will continue to maintain a steady and slow growth trend, the demand for high-performance NdFeB permanent magnet material will remain stable. With the development of China's fixed-frequency air-conditioning energy consumption standards and the popularity of foreign inverter air conditioner, the next few years, China's inverter air conditioner accounted for the proportion of total air conditioning will be greatly improved. At the same time, by the air conditioning compressor performance and volume constraints, the use of high-performance NdFeB permanent magnet material as the proportion of compressor magnets will become increasingly large. In the next few years, energy-saving inverter air conditioner and hybrid vehicles will gradually use our production of high-performance NdFeB permanent magnet materials as raw materials, demand will gradually rise. In 2014, China's high-performance NdFeB permanent magnet materials industry downstream demand distribution as shown below. Among them, energy-saving wind power equipment manufacturing, energy-saving elevator traction machine manufacturing, energy saving and environmental protection air conditioning, EPS energy-saving environmental protection motor and hybrid vehicle applications will be more than 2014 China's high-performance NdFeB permanent magnet material total demand of 80%.
