High Density Wet Compression Ferrite Motor Magnets For Starting Motor W2022
What does Xinheng offer to customers?
Our company manufactures an-isotropic Ferrite Motor Magnets 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.

Introduction Of Starting Motor:
Before the engine can operate under its own power, it must be rotated by an external force. The process by which the engine transitions from a static state to being able to operate on its own with the help of external forces is called the start of the engine. There are three common starting modes of the engine: manual starting, auxiliary gasoline engine starting and electric starting. Manual starting using rope pull or hand, simple but inconvenient, and labor intensity, only suitable for some small power engine, in some cars only as a backup way to retain; Auxiliary gasoline engine starting is mainly used in high-power diesel engine; The electric starting mode is easy to operate, fast to start, has the ability to start repeatedly, and can be controlled from a distance, so it is widely used by modern vehicles.
