NdFeB Curved Magnet

The NdFeB Curved Magnet is defined by its precise geometric conformity. Unlike flat blocks that approximate a curve in a polygon arrangement, these magnets are ground to a specific inner (ID) and outer diameter (OD). This true curvature maximizes the fill factor within a cylindrical housing, ensuring that the volume of magnetic material is utilized to its fullest potential within the available space.

Precision machining is the hallmark of this product. We hold tight tolerances on the radius and concentricity to ensure a uniform magnetic gap. A consistent gap is crucial for minimizing torque ripple and audible noise in electric motors. Furthermore, the curved shape aids in mechanical retention; when glued to a rotor hub or stator shell, the mating surfaces have full contact, providing a superior bond strength compared to flat magnets, which is critical at high centrifugal speeds.
