What is permanent magnet ferrite?
Permanent magnet ferrite has a very high magnetic energy product
and coercivity, it can produce a large magnetic field and magnetic
force under a small size and weight, while having a high magnetic
temperature coefficient and thermal stability, can maintain stable
magnetic properties at higher temperatures. This makes the
permanent magnet ferrite still able to work normally in a high
temperature environment and is not easy to lose magnetism. Good
corrosion resistance and wear resistance, so that it is not easily
affected by the external environment and damage.

What's the feature of ceramic strontium ferrite magnet made by wet
compression molding?
- Composition - Contain strontium ferrite (SrFe12O19) as the primary
magnetic material. Strontium ferrite has good magnetic properties
and is inexpensive to produce.
- Density - Have a high relative density of around 95% or more after
sintering. This gives good mechanical strength.
- An-isotropy - Exhibit strong magnetocrystalline an-isotropy due to
their hexagonal crystal structure. This results in a preferred
direction of magnetization along one axis.
- Particle shape - The strontium ferrite powder used typically has a
hexagonal platelet morphology which helps promote magnetic
an-isotropy during molding and sintering.
- Molding method - The powder is mixed with a liquid binder and
compression molded into a dense green compact using high pressures.
This orients the an-isotropic particles.
- Firing process - The compact is then sintered at high temperature
to develop density while preserving the induced magnetic anisotropy
orientation from molding.
- Remanence - Have a maximum magnetic flux density or remanence along
the axis of anisotropy, but little/no remanence perpendicular to
it.
- Coercivity - Usually have medium to high coercivity depending on
additives, density, and anisotropy level achieved.
What is variable frequency motor?
Inverter motor is a kind of motor that can adjust the speed
according to demand, also known as Inverter speed regulating motor.
The working principle is to adjust the frequency and voltage of the
motor input through the controller, so as to change the motor speed
and achieve accurate speed control.
Compared with traditional constant speed motors, Inverter motors
have higher energy efficiency and energy-saving performance, and
can adjust the speed at any time according to the load demand,
reducing energy consumption and operating costs. At the same time,
the Inverter motor also has more stable operation characteristics,
more accurate control performance and lower noise level, which is
suitable for a variety of occasions requiring precision control and
energy-saving operation.
