The role of permanent magnet ferrite in starting motor of motorcycle:
Permanent magnet ferrite plays a key role in motorcycle starting motor. It is often used as an exciting magnetic field of a motor, by generating a permanent magnetic field to drive the movement of the motor rotor. This permanent magnet ferrite has high permeability and low hysteresis loss, which can generate a strong magnetic field in the motor, thereby improving the efficiency and performance of the motor. At the same time, the permanent magnet ferrite also has stable magnetic properties and high wear resistance, which can ensure the stable operation of the electric machine for a long time. Therefore, permanent magnet ferrite plays a vital role in the motorcycle starting motor and is an important part of the normal operation of the motor.
 
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.

PHYSICAL PROPERTIES OF SINTERED FERRITE MAGNETS

 

 
What's the feature of ceramic strontium Permanent Magnets 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.
