Wear Resistant 2-Pole Ceramic Ring Rotor Magnet for Water Pump Motor, 2-poles Magnetization Ceramic Radial Ring Multi-pole Magnets, motor rotor permanent magnets, Radially Orientation Multipole Magnetic Ring, Anisotropic hard ferrite multi-polar magnetic rings for electronic motors
Wear Resistant 2-Pole Ceramic Ring Rotor Magnet for Water Pump Motor Features:
Specification size: custom design drawing
Magnetizing mode: Radial 2 poles
Magnet Tolerance: +0.1mm
Composition: Sintered Ferrite Magnet (hard ceramic)
Technical Requirements: The magnetic ring is divided into six grades. There is a small pit on the strong magnetic surface, and the temperature resistance is 120 degrees.
Multipolar magnetic rings are magnetized by special magnetizers on the top of hard magnetic rings. The effect of magnetization is related to the properties of magnetic rings and magnetizers. The magnitude of magnetic energy product and hysteresis attenuation are related to the above situation.
Magnet Factory HSMAG specializes in the production of motor magnets, motor multi-pole magnetic rings, injection moulding multi-pole ferrites. Welcome to inquire for samples or open-die customization
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.
Radial Magnets is good solution to instead of traditional segment magnets. they have following advantages :
Homogeneous distribution of magnetic field. Speed Motor Magnetic Ring 16-poles Ferrite Radial Magnetization
Geometric precision. Radial 12-Poles Ring Ferrite Magnets for Velocity Sensor
Variety of magnetic configuration
Design and assembly simplification
Precision of motor performances
The proportioning of permanent magnets, that is the ratio of the magnet pole areas to the magnet thickness (L/D-ratio) of any magnet material, is subject to the laws of physics. Axial 2-pole Radial Ring Ferrite Magnets for Electric Motor
The maximum operating temperature also depends on the L/D-ratio. A thin NeoDelta magnet disc of 15 ø x 2 mm e. g. can only be used up to a maximum operating temperature of + 70°C, whereas a thicker disc of 15 ø x 8 mm can be used up to approx. + 100°C.
In the case of most modern magnet materials the remanence and the coercivity decreases on warming.When the temperature drops both values rise. This generally means that there is an improvement in most magnet systems up to – 40°C. For example SmCo magnets can be used in temperature areas below zero, which are necessary for the production of superconductors.
The magnetisation of rod magnets with a kept-in preference direction (anisotropy) during production is possible only in the preference direction.
