Strontium Permanent Magnet Ferrite Is Used In Advanced Fan Motor
What does Xinheng offer to customers?
Our company manufactures an-isotropic ceramic strontium ferrite magnet made by means of wet compression molding
Introduction Of Fan Motor:
The fan motor is connected to an electrical power source, typically through a power cord. When the power is supplied to the motor, an electromagnetic field is generated within the motor.
The motor consists of two main components: the stator and the rotor. The stator is a stationary part of the motor and contains a set of electromagnetic coils. The rotor, on the other hand, is the rotating part of the motor and is attached to the fan blades.When the power is applied, an electric current flows through the coils in the stator, generating a magnetic field. The interaction between the magnetic field and the rotor creates a force that causes the rotor to rotate.
What's the key advantages of ceramic strontium ferrite magnets made by wet compression molding?
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.

Permanent magnet ferrite (also known as ferrite magnet) is a magnetic material composed of iron, oxygen, and other metallic elements (such as strontium or barium), widely used in motors, transformers, and other electrical equipment. In the fan motor, the application of permanent magnet ferrite is mainly reflected in the following aspects:
Improve efficiency: permanent magnet ferrite has a high magnetic energy product and can provide a powerful magnetic field, thereby improving the rotation efficiency of the motor and reducing energy loss.
Reduction of volume: Due to the high magnetism of permanent magnet ferrite, using the same specifications of the motor, the permanent magnet motor can be designed more compact than the traditional motor, reducing the volume and weight of the motor.
Noise reduction: Permanent magnet motors have lower vibration levels and run more smoothly than other types of motors, so noise can be reduced in products such as fans and user experience can be improved.
Improved starting performance: Permanent magnet ferrite motors have good starting torque and can be started at low current, which is suitable for fan products that require fast starting.
High temperature resistance: Modern permanent magnet ferrite materials can be designed to withstand high temperatures and are suitable for working in some high temperature environments, increasing the reliability of fan motors.
Cost effectiveness: Although the cost of high-performance permanent magnet materials is relatively high, due to its high efficiency and long service life, it can save operating costs in long-term use.
