Permanent Magnet Ferrite For Many Types Of Motorcycle Applications
What does Xinheng offer to customers?
Our company manufactures an-isotropic ceramic strontium ferrite magnet made by means of wet compression molding.
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.
-
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.

Introduction Of Motercycle Motor:
Motorcycle motor is the power source of the motorcycle, it is usually driven by fuel or electricity. The fuel engine is currently the most common type of motorcycle motor, which usually uses four-stroke, liquid-cooled or air-cooled technology, and can be divided into different models according to the size of the displacement.
Electric motorcycle motors are powered by electricity, and they usually use batteries as energy sources, which are more environmentally friendly, quiet and easy to maintain than traditional gas-powered motorcycles. Electric motorcycle motors usually use brushless DC motor technology, which provides high efficiency and good power output.
Whether it is fuel or electric motorcycle motors, they are a vital part of the motorcycle powertrain, determining the vehicle's performance and driving experience. With the development and innovation of technology, motorcycle motors will continue to evolve to meet the needs of users for more efficiency, more environmental protection and more power.
