Permanent Magnet Ferrite Tile Used In Automobile Lifting Glass Motor Car Ferrite Magnets W5168

Introduction Of lifting glass Motor:

The working principle of automobile lifting glass is mainly based on the cooperation of motor and mechanical transmission device
Control system:
Car lift glass is usually controlled by switches in the car, the driver or passenger can push these switches to raise or lower the window.
Motor:
When the button is pressed, the electric control system triggers the motor to work. The rotation of the motor provides power for the subsequent mechanical transmission.
Transmission mechanism:
The motor is connected to the lifting mechanism by a gear system or a rope (depending on the model). When the motor rotates, it drives the transmission, causing the lifting mechanism to move.
The transmission mechanism usually consists of a reel or pulley, which is rotated by the rotation of the motor, thus pushing the window up and down.
Guide and slider:
The lifting glass usually moves along the set guide rail to ensure the smooth lifting of the window. Rails provide guidance for window movement and prevent Windows from tilting or sticking.
There are usually sliders or brackets at the bottom of the window to work with the guide rail to facilitate the stability of the window when it is raised and lowered.
Safety device:
Modern automotive lift glass systems are often equipped with safety features, such as reverse functions. When the window encounters an obstacle during the lifting process, the sensor will detect and automatically stop or reverse the movement of the window to prevent nip or damage.

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.​​
