Fan Shaped Magnet C-8
Axial magnetization, planar magnetic poles called fan magnets.
Radial magnetization, the magnetic pole of arc surface is called tile magnet.
It is theoretically possible to make one or more pairs of poles in the direction of magnetization. The circle can be magnetized in radial direction, and 24 poles and 48 poles can be made on the arc surface. And the magnetic poles of the fan magnet are radiating, radial, parallel, planar, and planar multipoles.
Fan magnet is mostly VCM magnetic steel, used in the voice coil motor more.
To cut the magnet neatly, a slicer knife is usually used, but the magnet should be fixed first and the slicer adjusted to size before cutting. Its shape section processing methods are: grinding section processing, laser section processing, electrical spark section processing.
In practical application, the shape and properties of ndfeb permanent magnet are various, such as: disc, cylinder, ring, cylinder (with inner hole); Square, square; Fan, tile, trapezoid, groove, polygon and irregular shape. The size, performance, tolerance, and magnetization of each permanent magnet in different shapes are different. Magnets in the production process of hard to do a molding, shenzhen Mr Al magnetoelectric general production process are output large (large size) blank, after dealing with the sintering and smelting in through the mechanical processing, including cutting, punching, chamfering peace grinding, the surface coating processing, then the magnetizing treatment. It is best to carry out dimensional precision, surface quality, smoke test and other inspection packaging shipment.
Fan gear drive lifting permanent magnet, as the name implies, is obviously a lifting permanent magnet driven by fan gear. Specifically, this type of lifting permanent magnet is an electric lifting permanent magnet driven by electric motor and electric power source.
