Multipole magnetic ring is a non-standard customized product. Each magnet product of our company is manufactured according to the customer’s demand, such as: magnetization method and pole number, tolerance dimension, magnetic force size, etc.

Widely used in water pump injection moulding rotors,
1) Wet anisotropic ferrite,
2) 2 poles magnetized diametrically,
3) Y30BH Sr(strontium) ferrite, surface gauss is up to 1700 Gs,
4) Tolerance of out diameter is +0/-0.05, to guarantee perfect concentricity,
5) the groove/slotting and oval shape inner hole ensure the stablity of plastic injection.

Please let us know the specification, quantity and surface magnetic field strength of the multipolar ring ferrite you want to buy. We will reply you as soon as we receive your inquiry.
Our company can provide ferrite rotor separately or injection molding as a whole, and accept customization. Welcome to inquire our company about the specifications of ready-made (or near) ferrite multipole rotor magnet.

Hard ferrite magnets
Barium ferrite and strontium ferrite are sintered metal oxides BaO2 or SrO2 combined with Fe203.
Raw materials for such magnets are abundant and inexpensive. Hard ferrites are the most used permanent magnet materials worldwide. They are made isotropic or anisotropic. Radial Magnetization Multipolar Tube Ferrite Magnets
Isotropic magnets have nearly the same magnetic properties in all directions. They can be magnetised accordingly. Their magnetic energy is low, so is their price.
Anisotropic magnets are compressed in a magnetic field, resulting in one preferred direction of magnetisation. In comparison to isotropic magnets their energy density is about 300 % higher. The coercivity is high in relation to the remanence. This means that such magnets must have a large pole area, i.e. circular magnets must have a disc shape and not a rod form.
Hard ferrites have a high temperature coefficient. The remanence decreases by about 0.2% per degree C. They can be used between – 40 and + 200°C. Like ceramic materials, they are mechanically hard and brittle. Being oxides they do not corrode and are neither affected by climatic influences nor by many chemicals, with the exception of some strong acids. Machining is only possible with diamond tools.
