Ndfeb magnet wide prospect of market

In recent years, TC51 in around the world are widely used on the work surface mount components, formulated the IEC61860:2000 'the size of the magnetic oxide of low magnetic core' it provides a series of surface mounting transformer magnetic core size standards. Forthcoming issue IEC62024 the high frequency sensitive device performance and measuring method, part 1: na hang chip inductors, the scope, IEC62025 the high-frequency perceptual element of performance and its measuring method, part 1: electronic communication equipment installation fixed inductance with surface will become the chip inductor component based standards. In addition, as a new work TC51 project proposals, the number of components with noise suppression piece part 1: terms and definitions part 2: measurement method was also on the agenda; IEC62211 'inductive components reliability management' will appear as a new IEC standard type. TC51, meanwhile, also make some adjustment in the standard system, the standard to be in the form of a series of recent years TC51 a new feature of standard. Like IEC60424 series standards: ferrite core surface defects limit guide, part 1: general part, part 2: RM magnetic core, part 3: EPD core and E core, part 4: the annular core; IEC60401 series standard: core term of soft magnetic materials, part 1: terms, part 2: physical defects reference size part 3: transformer and inductor core manufacturer catalogue data guide; IEC62044 series standard: soft magnetic materials magnetic core measurement methods, part 1: general part, part 2: low excitation level under magnetic properties, part 3: high magnetic properties under excitation level and so on. In addition, this year TC51 also launched a & other; Throughout the public available specification &; ( 没有) The draft, the inductance proximity switch made of magnetic oxide half cylindrical magnetic core size ', to accelerate the development of magnet technology in the field of standardization. Ndfeb magnet wide prospect of market, in recent years, as a result of ndfeb magnets to further improve the comprehensive performance of ndfeb magnet has become the mainstream market has gradually replace other magnetic materials magnetic materials. As a result of high efficiency and energy saving, light quality, small volume, good speed regulation characteristics of ndfeb is widely used in wind power, new energy cars and energy-efficient appliances such as sunrise industry. In the backdrop of the energy conservation and environmental protection, ndfeb is welcoming new development opportunities. At the same time, countries have introduced the related policy, vigorously promote the development of ndfeb industry. Support fund of 500 million yuan, the key support of rare earth resources used in wind power, electric cars, energy-efficient appliances, maglev trains, and other fields, the support of national policy is undoubtedly the most powerful industry for the future development of rare earth permanent magnet industry. In a ferromagnet, the local magnetic moment can rotate and arranged in a different direction. At absolute zero, the magnetic moment to arrange make the magnet produces the strongest magnetic; As temperatures rise, more the spin magnetic moment become more out of sync, magnetic force will be weakened. The magnetic vibrator is increased with the temperature. Magnetic vibrator is a kind of quasiparticle, the magnet is formed by rotating magnetic moment together, also called & other; Since the spinor & throughout; 。 Magnon like electronics. Powerful magnet electronic can also carry a charge and heat conduction, can under the effect of electric field or temperature difference movement, thermoelectric effect is the phenomenon. According to physicists organization network (July 29, Beijing time) , scientists have been studying the thermoelectric effect, such as thermoelectric generators to convert heat directly into electricity, or without any moving parts to refrigeration. Magnetic vibrator can also under the action of two kinds of force movement: temperature and magnetic field. The researchers developed the pyroelectricity described in the electronic transmission of boltzmann transport equation, after derivation got two new equations to describe the magnon transmitted. They can use the new equation to predict magnon refrigeration effect, similar to the thermoelectric refrigeration effect. When there are differences between the magnon in magnetic field, one end will carry heat from magnet moves to the other end. They use ordinary magnetic dielectric model are constructed and collected the data of the material from the previous data input in the new model, found a moderate magnetic field gradient, it can produce smaller cooling effect; And under the condition of low temperature, cooling effect is more obvious.
