Product description
Rare Earth Ring Ferrite Magnet Motor
Ferrite
magnets, sometimes referred to as ceramic because of their production process,
are the least expensive class of permanent magnet materials. The material
became commercially available in the mid 1950's and has since found its way
into countless applications including arc shaped magnets for motors, magnetic
chucks and magnetic tools.
The raw
material - iron oxide - for these magnets is mixed with either strontium or
barium and milled down to a fine powdered form. The powder is then mixed with a
ceramic binder and magnets are produced through a compression or extrusion
molding technique that is followed by a sintering process. The nature of the
manufacturing process results in a product that frequently contains
imperfections such as cracks, porosity, chips, etc. Fortunately, these
imperfections rarely interfere with a magnet's performance.
