    Radially-oriented ring magnets are a unique subset of NdFeB bonded magnets. Using proprietary technologies, a multipole ring can be sintered into a truly radial geometry. This replaces the costly and labor-intensive method of gluing arcs, bread loaves or rectangular segments onto a rotor shaft.

    MPCO Magnetics now offers high-efficiency multipole Neodymium (NdFeB) magnetic rings. These rings are revolutionizing the permanent magnet space for synchronous motors, stepper motors and DC brushless motors widely used in automotive, specialty electronics, and medical applications. Neodymium Rare Earth Magnet Ring Grade N45 OD1.26 x ID1/2 x 1/4″Thick

    Magnets are pressed to produce sintered NdFeB magnets. This process consists of combining base powders, pressing the resulting material, and then baking or sintering the resulting ring to achieve a radially magnetized product.

    Bonded Neodymium magnets are made of the powerful Nd-Fe-B material mixed into an epoxy binder. The mix is appropriately 97 vol% magnet material to 3 vol% epoxy. The manufacturing process involves combining Nd-Fe-B powder with an epoxy binder and compressing the mixture in a press and curing the part in an oven. Permanent Radiation Oriented Ring Magnets

    Advantages:
    1.Produced with high efficiency, stability and repeatability.
    2.Magnet and other part may form together in one step.
    3.Free choice of magnetizing direction-especially for multi-polar applications.
    4.High dimensional accuracy-large quantity applications with minimum post-press machining.
    5.Thin-wall ring and complex shape magnets.
    6.High resistance to corrosion. 10-Poles Bonded NdFeB Diametrically Ring Magnet
