The application of sintered ndfeb permanent magnets, rounding

by:Newland     2020-05-04
Sintered ndfeb permanent magnets can compared with other permanent magnet magnetic advantage. It has a very high magnetic energy product, coercive force and energy density, known as 'magnetic king', and its mechanical performance is good, easy processing. These excellent performance make sintered ndfeb permanent magnets in the modern industry and the wide application of electronic technology, is one of the more common permanent magnet motor, speaker, magnetic separator, computer disk drives, magnetic resonance imaging equipment instrument, etc. In 2000, the production of rare earth permanent magnet ferrite for the first time in 2010, production of sintered ndfeb permanent magnet also full beyond ferrite, become permanent magnet industry worthy of the name 'leading role' in accordance with the manufacturing process, ndfeb is divided into sintered and binding two, two characteristic to magnet performance, making them in the application and each has its own characteristics. Sintered ndfeb permanent magnet is the highest yield, the most widely used of rare earth permanent magnet materials. Sintered ndfeb possesses high magnetic energy product and high coercive force and high working temperature, but its preparation tolerance is bigger, shape, degree of freedom is small, so is mainly used in large and medium-sized motor, wind turbines, high fidelity speakers and so on. Shown below for sintered ndfeb permanent magnets used map.
