Product description:
Arc Segment Magnets is one special shape of permanent magnets, which widely assembly into rotor and stator of PM Servo motors. It is always manufactured via Wire Cutting and grinding machining process etc .  With rich experience on serving for motors manufacturer, Dunben Magnet can produce all shapes of arc segment magnets with different coatings, such as NiCuNi, Black Ni, Epxoy and Phosphatised coating.

Generally, arc segments are anisotropically aligned through the outer and inner radii of the segment. After the magnet has been surface ground to profile the Arc radius or pressed, we magnetized it through the radius of the arc. (See diagram below)
