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 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 is variable frequency motor?

Inverter motor is a kind of motor that can adjust the speed according to demand, also known as Inverter speed regulating motor. The working principle is to adjust the frequency and voltage of the motor input through the controller, so as to change the motor speed and achieve accurate speed control.
Compared with traditional constant speed motors, Inverter motors have higher energy efficiency and energy-saving performance, and can adjust the speed at any time according to the load demand, reducing energy consumption and operating costs. At the same time, the Inverter motor also has more stable operation characteristics, more accurate control performance and lower noise level, which is suitable for a variety of occasions requiring precision control and energy-saving operation.
