Advanced Permanent Magnet Ferrite for Motorcycle Engine Ignition Systems

Advanced Permanent Magnet Ferrite Used In Motorcycle Engine Ignition Systems

What does Xinheng offer to customers?

Our company manufactures an-isotropic ceramic strontium ferrite magnet made by means of wet compression molding.

Permanent magnet ferrite plays an important role in motorcycles, mainly reflected in the following aspects:

Engine ignition systems: Permanent magnet ferrite is commonly used in motorcycle ignition systems, especially in sparkless ignition (CDI) systems. Its powerful magnetic field provides a steady current that ignites the fuel-air mixture, improving engine starting performance and operating efficiency.

Generators: Many motorcycles use permanent magnet generators, which use the magnetism of permanent magnet ferrite to generate electricity. The permanent magnets in the generator interact with the coils to convert the mechanical energy to electrical energy, providing the required energy for the motorcycle's electrical system.

Sound and vibration control: Permanent magnet ferrite materials, due to their excellent magnetic and mechanical properties, can be used to reduce the vibration and noise of motorcycle components, providing a more comfortable riding experience.

Sensor applications: In motorcycles, permanent magnet ferrite is also widely used in various sensors, such as speed sensors, position sensors, etc. These sensors use permanent magnet materials to sense changes and transmit relevant information, improving motorcycle safety and performance.

Electric motorcycle: In electric motorcycles, permanent magnet ferrite is used in the motor, as one of the important components, to improve the efficiency and power output of the motor, and then improve the performance of the whole vehicle.

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's the key advantages of ceramic strontium ferrite magnets made by wet compression molding?

• Low cost - Strontium ferrite is inexpensive and the wet molding process is relatively simple. This makes them cheaper than rare-earth magnets.

• High magnetic property-Even without heavy rare earth element additions, strontium ferrite magnets can achieve coercivities of 700-1000 kA/m, making them suitable for many applications.

• Dimensional consistency - The compression molding process allows for close dimensional tolerances and uniform magnet shapes to be produced consistently.

• Temperature stability - Strontium ferrite magnets have high Curie temperatures, typically around 450-470°C. They maintain good magnetic properties over a wide operating temperature range.

• Resistance to corrosion - Being fully dense ceramic materials, they are not prone to corrosion like bonded magnets containing additives.

• Mass production capability - The molding process is amenable to automated high-volume manufacturing of complex magnet geometries.​​
