Since 2002 , focus on manufacturing and supplying various kinds of bonded ferrite magnets

     

The effect of magnetic tile and classification

Is the purpose of the magnetic tile in permanent magnet dc motor, and through the excitation coil electromagnetic motor produce different magnetic potential source, permanent magnet motor is a permanent magnetic material to produce constant magnetic potential source. Permanent magnet magnetic tile instead of electric excitation has many advantages, can make the motor has simple structure, convenient maintenance, reliable, small volume, light weight, less use amount of copper, copper low consumption, low energy consumption, etc. Magnet, a kind of is mainly used in electrical appliances, a magnet is also called the magnets, magnetic tile, etc. Multiple names, shape also is the same as before building a house with the kind of tile as shown in figure: magnetic tile are divided into ferrite magnetic tile and 1, sintered ndfeb magnetic tile ferrite magnetic tile production process is mainly divided into wet working pressure of the opposite sex, gay, pressure of the opposite sex, is the difference between the straight and gay, if there is a magnetic field orientation is to press molding. Here mainly introduce wet wet compression process is: the pressure of the opposite sex process raw materials - — Presintering - — Coarse grinding, A ball mill) — — Ingredients - — The second ball mill ( Wet milling) — — Magnetic field shape - — Sintering - — Grinding - — Clean - — The magnetization. For forming slurry contains water, than dry pressing molding particles in magnetic field easy to the opposite sex can obtain higher orientation degree, its performance is also higher. 2, sintered ndfeb magnetic tile: ingredients - — Smelting - — Broken - — Flour - — Magnetic field shape - — Isostatic pressing - — Vacuum sintering and temper - — Such as wire cutting processing - — Electroplating - — The magnetization
