Stable Permanent Ferrite Magnets That Provide High Coercivity In Automotive Motors

In recent years, with the rapid development of the new energy vehicle industry, significant technological breakthroughs have been achieved in the application of permanent ferrite materials in this field. These technological breakthroughs not only enhance the performance and efficiency of new energy vehicles, but also reduce costs and promote the sustainable development of the industry

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

FERRITE POWDER GRADE OF MOTORCYCLE MOTORS MAGNET

Application in electric power steering (EPS) system:

In electric power steering systems, the magnetic properties of permanent magnet ferrite are widely used in the design of motors and sensors:

Motor design: Permanent magnet motor is often used in electric power steering system, permanent magnet ferrite as the permanent magnet of the motor, which can provide continuous magnetic field, thereby improving the efficiency and response speed of the motor. Compared with traditional motors, permanent magnet motors have higher power density and can achieve greater output power in a smaller volume.

Sensor application: In the steering system, the accurate detection of Angle, torque and other parameters is very important. The permanent magnet ferrite can be used in conjunction with the Hall effect sensor to accurately feedback the steering state through its magnetic field changes to ensure the safety and handling sense of the vehicle.
