Ferrite Arc Magnets

Ferrite arc magnet is a kind of functional electronic component, called motor
magnet, which is mainly used in DC micro motor. The magnetic properties of
ferrite motor magnets tile show that they have high permeability at high
frequency. In addition to the magnetic properties, dimensional tolerances and
appearance of the permanent ferrite arc (segment) magnets meets the national
standards and user needs. Another important criterion is mechanical strength.
If the mechanical strength is not enough, the ferrite motor magnets will break
during the installation and use, resulting in the scrapping of the motor.
Generally, ferrite magnets used for small motors where there is no requirement
for power density and torque density, such as water pump motor

Characteristics of Arc Ferrite Magnet
The arc(ferrite segment magnets) shaped permanent magnets mainly made of SrO or
Bao and Fe2O3 by sintering, which seems to be part of the ring magnets, are
called ferrite arc/segment/tile magnets. Ferrite arc(segment) have the
characteristics of low magnetic energy, not easy to corrode and not easy to
demagnetize. In the whole permanent magnet industry, arc(segment) shaped
ferrite magnets are the most important industrial magnets for various motors.

Production Process Of Ferrite Tile Magnets
The production process of sintered ferrite(ceramic) tile magnets are mainly
divided into wet pressing anisotropic, dry pressing isotropic and dry pressing
anisotropic. The difference between the isotropic and the anisotropic lies in
whether there is orientation magnetic field during the pressing. Here, the
process of anisotropic wet pressing is mainly introduced.

Wet compression process is: raw material - presintering - coarse crushing (a
ball mill) - ingredients - the second ball mill (wet) - magnetic molding -
sintering - clean grinding - the magnetization.

Because the forming slurry contains water, the forming particles are easy to
turn in the magnetic field, so it can obtain higher orientation than dry
pressure, and its performance is higher
