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

Introduction Of automobile wiper motor:

Permanent magnet ferrite plays a key role in automobile wiper motor. It is commonly used as an excitation source for a motor, helping the motor generate the desired torque by generating a constant magnetic field. This material has a high permeability and coercivity, making it particularly suitable as an auxiliary electromagnetic field source. Since the wiper motor needs to operate in a variety of harsh environmental conditions, the stability and durability of permanent magnet ferrite also makes it an ideal choice. Therefore, permanent magnet ferrite in automotive wiper motor can ensure the efficient operation of the motor and improve its reliability.
