Product Overview

Our arc segment neodymium magnets are designed for motor and actuator applications where curved magnets are needed to fit rotors or stators. Made from premium NdFeB (neodymium-iron-boron), these magnets provide strong and stable magnetic force, allowing precise control of torque, rotation, and efficiency.

We offer customizable inner/outer diameters, thickness, and arc angles, along with various coatings and magnetization directions, suitable for both prototyping and bulk production.
