Ndfeb magnet for permanent magnet motor can produce effect

by:Newland     2020-04-22
Ndfeb magnet for permanent magnet motor can produce effect compared with the traditional electro-magnetic motor, permanent magnet motor has a structure brief, stable operation, small volume, light weight, low loss, high power, flexible and varied in shape and scale of the motor and other obvious advantages. With the use of traditional permanent magnet ndfeb magnet material of permanent magnet motor, permanent magnetic material of the new permanent magnet motor using high performance ndfeb magnet volume smaller, lower loss, power is significantly higher than the traditional permanent magnet motor. It is worth noting that the energy conservation environmental protection air conditioning and hybrid cars now demand for high performance permanent magnet ndfeb magnet materials mainly through acquisitions Japan produces high performance permanent magnet ndfeb magnet material and satisfactory, now temporarily not choose high performance permanent magnet ndfeb magnet materials in China. The use of permanent magnet motor is extremely gf, widely aviation, spaceflight, national defense, equipped with production, industrial and agricultural production and daily life of each category: its capacity from big to small, has now reached megawatts, using range is more and more extensive; Its status is more and more important, from military to civilian use, from special to general category, not only in the micro &special motor box, and in the electric drive system is also showing strong vitality. Permanent magnet motor is divided into ferrite excitation motor and permanent magnet motor. Motor is a magnetic field as a medium for mechanical energy and electrical energy transformation of electromagnetic devices to each other. Set inside the motor for electromechanical energy transformation required for the air gap magnetic field, there are two ways: within the motor winding current flow, requirements are both special winding and the corresponding equipment, provide the energy demand to maintain current flow, commonly referred to as the electric excitation motor, such as dc motor and synchronous motor; A permanent magnet to had a magnetic field, can simplify the machine structure, and can save energy, this is a permanent magnet motor. Permanent magnet motor is high-power ( High speed, high torque) , high functional and miniaturization direction, and constantly develop a new type motor and using category. Now, China's high performance permanent magnet ndfeb magnet materials mainly mean there are two types of professional, traditional dirty occupation, contains the VCM motor and personal consumer electronics products; New energy, energy conservation and environmental protection career, including wind power generation equipment, elevator traction mechanism of energy conservation, energy conservation and environmental protection air conditioning ( Frequency conversion air conditioning) , EPS and hybrid cars. Permanent magnet motor is a kind of high efficiency and energy saving products, even save electricity rate is as high as 10% above, use of high performance permanent magnet ndfeb magnet data of permanent magnet motor can save electricity rate is as high as 15% ~ 20%. In wind turbine and compressor needs infinite frequency control of motor speed, permanent magnet frequency control of motor speed to save electricity rate is as high as 30% above. The world advanced level of motor energy conservation is the fan running power itself is in commonly 80%, system running power at 85%. Specializing in the production of magnets, ndfeb, rubber magnetic, ferrite magnet products. This factory independent production, sales, products of good quality, price concessions.
