Anisotropic ferrite magnets Rings
The magnetic flux density differs slightly depending on the measuring device. Please consider them to be only reference values.The adsorptive power is the reference value when the magnet is pulled at a perpendicular angle.
Radial ceramic ferrite is widely used in sensor, washing machine, drainage pump, aquatic submersible pump and other industries.
Which products are the radial multipole magnetic ring mainly used in?
customer needs, 2 poles, 4 poles, 8 poles, 12 poles, 18 poles, 24 poles, 32 poles, 48 poles, etc.
Radial 2-pole ferrite magnets are commonly used in dishwashers, washing machines and pump rotors.
Radial 4-pole ferrite magnet is often used in fish tank water pump and pump motor.
Radial 6-pole ferrite magnets are commonly used in household appliances, magnetic pumps and water flow sensors.
Radial 8-pole ferrite magnetic rings are commonly used in air conditioning, fan motors and oil-electric hybrid vehicles.
Radial 12-pole ferrite magnetic rings are mostly used in air-conditioning, automotive oil pump motor, motor testing.
Radial 16-pole ferrite magnetic rings are used in mahjong machines, air-conditioning motor rotors and DC brushless motors.
Even if they are of the same size and look the same, magnets have completely different properties depending on which side is the N pole and which side is the S pole. Orientation of magnetization is determined during the production process. After the material is made, during the final process the material is magnetized with a magnetization coil in the direction of orientation. Please check the differences in magnetic domains and direction of magnetization to determine the suitable direction for your material. Wear Resistant 2-Pole Ceramic Ring Rotor Magnet for Water Pump Motor
Ferrite magnets made of barium ferrite and strontium ferrite are compressed and then heat treated at a high temperature by sintering. They acquire their shape through a magnetic field during compression. As a result the powdered parts take on a geometric alignment in the later direction of magnetisation.
Keeping in the preference direction (anisotropy) considerably improves the remanence. A magnetisation is only possible in the predetermined preference direction. The following standard magnets are magnetised in the preference direction designated by N-S.
Ferrite magnets correspond to any ceramic material in terms of hardness and brittleness and can only be machined with diamond tools. As a ceramic material, hard ferrite magnets are resistant to weathering and to many chemicals such as solvents, alkaline solutions, salts, weak acids, lubricants and harmful gases. Hard ferrites are the most inexpensive and most widely used permanent magnets worldwide. A rise in temperature per 1 °C leads to a reduction in the flux density by 0.2% while the coercivity increases by 0.3% at the same time.
A reduction in temperature increases the flux density and lowers the coercivity by the same amount.
