Tile shape magnet, tile shape magnet ( Effect of magnetic field distribution order)

Magnet, a kind of is mainly used in electrical appliances, a magnet in general people are not very understanding, so, xiaofu today with everyone to introduce tile shape magnet, and its function, the magnetic field distribution and so on. What is the tile magnet? Magnet, also called magnets, magnetic tile, etc. Multiple names, shape also is the same as before building a house with the kind of tile, the following figure. What is the main purpose of tile shape magnet? Magnetic tile mainly used in the permanent magnet dc motor, and through the excitation coil electromagnetic motor produce different magnetic potential source, permanent magnet motor is a permanent magnetic material 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. Motor magnetic tile 'exchange coupling effect in ferromagnetics' there is a strong between adjacent electronic 'exchange coupling effect, in the case of no external magnetic field, they can spin magnetic moment in a tiny area' spontaneously 'spontaneous magnetization lined up together to form a small area, known as magnetic tile. Without magnetization ferromagnetics, although there are certain each magnetic tile internal spontaneous magnetization direction, there is a lot of magnetic, but a lot of different magnetization direction of the magnetic tile and the ferromagnetic mass do not show. When electric ferromagnetics in external magnetic field, the spontaneous magnetization direction and Angle of the external magnetic field direction into small magnetic tile as with the increase of the magnetic field and to expand its volume, and further make the magnetization direction of the magnetic tile to external magnetic field direction. Classification of magnetic tile ferrite tile is given priority to with sintered ferrite, ndfeb strong magnetic magnetic tile divided into two categories, sintering and adhesion, in addition to samarium cobalt magnetic tile. 1, the sintered 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, is whether the press molding has a magnetic field orientation. Here introduces 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 guess you concern: tile shape of ndfeb magnet magnetic field will be uneven learned, tile shape magnet axial magnetic field is part of the uniform, radial couple value is high, for reference only. The company for the entities magnet factory, magnetic tile specifications, performance and so on all can be customized processing, welcome to the drawings. Magnetic tile hits more articles recommended; Teach you know magnet tiles, magnetic tile magnetic tile specifications written format related knowledge introduction, magnetic tile, Installation classification of magnetization)
