Circular Segment Type Permanent Ferrite Magnets For Automotive Motors W031E

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.

• 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.​​

AUTOMOBILE MOTORS MAGNET SPECIFICATION TABLE

Introduction Of Oil Pump Motor:

Pump Motor Power A modified specific motor that drives an oil pump. The oil pump motor includes the motor body, the front end cover and the output drive shaft. A stepped hole is opened on the front end cover, and the output drive is retracted into the front end cover for a hollow shaft. The shaft hole aperture is matched with the outer diameter of the input drive shaft of the oil pump. The pump is divided into high pressure and low pressure: that is, the high pressure plunger pump relies on the camshaft in the pump to drive the plunger to move up and down in the plunger sleeve to produce high pressure oil supply to the injector.

Permanent magnet ferrite is an important permanent magnet material with many advantages. Here are the main advantages:

High permeability: Ferrite has a high permeability, which can effectively concentrate the magnetic flux and improve the magnetic field strength.

Good temperature stability: Ferrite materials maintain good magnetism over a wide temperature range and are suitable for various environments.

Low cost: Ferrite material is relatively cheap, low production cost, suitable for large-scale manufacturing.

High resistivity: Ferrite has a high resistivity, can effectively inhibit eddy current loss, suitable for high frequency applications.

Corrosion resistance: Compared with other types of magnetic materials, ferrite has strong corrosion resistance to the environment and is suitable for use in humid or corrosive environments.

Small size: permanent magnet ferrite is small in size and light in weight, which is very suitable for miniaturized electronic devices and motors.

Variety of shapes and sizes: Ferrite materials can be manufactured into different shapes and sizes according to demand, with high flexibility.
