    Magnetic Products Inc. can offer high efficiency multipole magnetic rings. These Neodymium (NdFeB) rings are revolutionizing the permanent magnet space for synchronous motors, stepping motors and DC brushless motors widely used in automotive, computers, electronics, communications, office, school equipment and common household products. Until recently, full magnetic rings were made of separate magnets joined together to create the desired ring shape. Now new technology enables the creation of super strong, one piece, multi-pole radial magnetic rings.

    Multipole Neodymium Ring Magnets Technology:
    This process consists of combining nanocrystalline base powders, pressing the resulting material, and then baking or sintering the resulting ring to achieve a radially magnetized product. This new technology improves the magnetic flux which in turn provides better efficiency and performance.

    Available Dimensions:
    O.D I.D Wall Thickness(T) Height(H)
    <70mm >15mm 2<T<5mm 25-50mm
    Special sizes may be produced depending on the grade, height-to-diameter ratio, and wall thickness.
