Permanent Magnet Ferrite Ceramic Segment For Automobile Glass Lifting Motor

Product Specification

The Permanent Magnet Ferrite Ceramic Segment Is Used For Automobile Glass Lifting Motor
 

Automobile glass lifting principle:

The working principle of electric glass regulator: The electric fork arm glass regulator is composed of ordinary manual glass regulator, reversible DC motor and reducer. The working principle is to open the motor, the motor drives the output power of the reducer, and the glass installation bracket is moved by the active arm and the driven arm or the steel wire rope, forcing the glass of the door and window to move up or down in a straight line.

The role of permanent magnet ferrite in automobile glass lifting motor:
 
Permanent magnet ferrite plays a key role in automobile glass lifting motor. It is usually used as the stator of a motor, providing a stable magnetic field so that the motor can operate properly. Permanent magnet ferrite has excellent magnetic properties, can provide sufficient magnetic field strength and stability in a small volume, and has the characteristics of heat resistance and corrosion resistance, which is very suitable for automotive glass lifting motor such as high temperature and wet working environment. When the motor is working, the magnetic field generated by the permanent magnet ferrite can interact with the rotating part of the motor (rotor), so as to achieve the lifting function of the glass. Therefore, permanent magnet ferrite plays a crucial role in the automotive glass lifting 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.
