To be a world-class magnet supplier
Application point of view, by using a large number of high-performance NdFeB permanent magnet materials play a role in the motor, the motor using permanent magnet materials are usually referred to as a permanent magnet motor. Permanent magnet motor is divided into the ferrite exciter motor and a rare earth permanent magnet motor. The magnetic field of the motor is as a medium for the mechanical energy and electrical energy conversion of the electromagnetic device. Establish electromechanical energy conversion, the required air gap magnetic field in the motor, there are two ways: through current generated in the motor windings, both need to have a special winding and corresponding apparatus, the need to continue to provide energy to maintain the current flow, usually called excitation electric motor, such as ordinary DC motors and synchronous motors; permanent magnets to generate a magnetic field, can simplify motor structure, but also save energy, which is a permanent magnet motor.Application of permanent magnet motor is extremely GF, throughout all fields of aviation, aerospace, defense, equipment manufacturing, industrial and agricultural production and daily life: its capacity from largest to smallest, has now reached megawatts, an increasingly wide range of applications; their status more and more important, from military to civilian use, from the particular to the general fields, not only in the dominant micro motor and electric propulsion system shows strong vitality. Compared with traditional electrical excitation motor, rare earth permanent magnet motor has a simple structure, reliable operation, small size, light weight, low loss, high efficiency and flexibility of the shape and size of the motor significant advantages. Compared to the production and application of traditional NdFeB rare earth permanent magnet motor, the application of high-performance NdFeB permanent magnet materials, new rare earth permanent magnet motor is smaller, loss and lower efficiency significantly higher than conventional rare earth permanent magnet motor . The rare earth permanent magnet motor is an energy-efficient products, the average saving rate up to 10% more than the application of high-performance NdFeB rare earth permanent magnet motor energy-saving rate can be as high as 15% to 20%. Wind turbine, compressor and other needs stepless frequency control Occasions, permanent VVVF saving rate up to 30% or more. International advanced level of electrical energy and operating efficiency of the wind turbine itself is generally more than 80%, the efficiency of the system is running in about 85%. The body of our domestic equipment design efficiency of 70%, less than 30% of the efficiency of the system operation, the power wasted very serious. The combination of frequency control, according to a report on the work of the international energy agency (IEA) in July 2006, by improving the efficiency of the motor can save about 7% of the electricity, which is roughly 1/4 to 1/3 is obtained by increasing the efficiency of the motor. For the coordination of national energy efficiency grading standards, in 2006, the International Electrotechnical Commission (IEC) to develop an energy efficiency standard IEC60034-30. The standard general purpose motor efficiency levels IE1, IE2, IE3, IE4 four, which IE1 standard efficiency, equivalent to China's current production level of your ordinary series of induction motor efficiency; IE2 high efficiency, than ordinary motor average 2.75% increase in efficiency losses dropped by an average of about 20%; IE3 for ultra-high efficiency, to further increase the efficiency of 1.5% to 2% loss reduced by 15%, only the United States in 2010 is expected to reach the IE3 level of energy consumption, to enforce; The IE4 super ultra-efficient, the loss is expected to further decreased by about 20%. On the whole, the application of high-performance NdFeB rare earth permanent magnet motor easy to achieve high efficiency, that is, to achieve the the IE2 level of efficiency values. Rare earth permanent magnet motor forward high-power (high-speed, high-torque), high functionality and miniaturization direction ever-expanding variety of motor and application areas. At present, the main downstream industry of China's high-performance NdFeB permanent magnet materials are divided into two categories, traditional downstream industries, including the VCM motor and personal consumer electronics products; new energy and energy-saving and environmental protection industry, including energy-efficient wind power generation equipment, energy-saving elevator drag cited machine manufacturing industry, energy saving and environmental protection air conditioning (inverter air conditioner), EPS and hybrid cars. It is worth noting that energy saving air conditioning and hybrid vehicles for high-performance NdFeB permanent magnet materials demand is met through the procurement of high-performance NdFeB permanent magnet materials produced in Japan, and is currently available for the selection of high properties of Nd-Fe-B permanent magnet materials. In the next few years, China's energy-saving wind power equipment industry, energy-saving elevator traction machine manufacturing industry, hybrid cars, and EPS manufacturing industry will be rapid development as the country of the new energy, energy saving work of attaching increasing The demand for high-performance NdFeB permanent magnet materials will grow rapidly; and VCM motor and personal consumer electronics products in general will continue to maintain a stable trend of slow growth, the demand for high-performance NdFeB permanent magnet materials will remain stable. With our fixed-frequency air conditioning energy consumption, the development of standards and the popularity of foreign inverter air conditioner, inverter air conditioner in China accounted for in the next few years, the proportion of air conditioning total will be increased dramatically. At the same time, by the performance of the air-conditioning compressor and volume restrictions, the increasing use of high-performance NdFeB permanent magnet materials as the proportion of the compressor magnet. In the next few years, the energy-saving inverter air conditioner and hybrid vehicles will be gradually selection of high-performance NdFeB permanent magnet materials produced in our country as a raw material, demand will gradually climb. In 2014, China's high-performance NdFeB permanent magnet materials industry downstream demand distribution as shown below. The energy saving wind power equipment manufacturing, energy-saving elevator traction machine manufacturing, energy conservation and environmental protection air conditioning, EPS energy saving and environmental protection motors and hybrid electric vehicle applications 2014 China High-performance NdFeB total demand will exceed 80%.
