Product Description

N32-N52 Neodymium Arc Magnets for Alternator Rotor Industrial Permanent Magnets

Custom Grade Rare Earth Arc Magnets with High Magnetic Strength
Engineered neodymium arc magnets (segment magnets) featuring high coercivity and precise dimensional tolerance, designed for high-efficiency electric motor and alternator applications.

Product Overview

Neodymium arc magnets are a high-performance rare-earth magnet solution optimized for motor rotor assemblies, offering exceptional magnetic strength and stability across industrial and automotive applications. Widely used in permanent magnet motors, these arc-shaped segments provide uniform magnetic flux distribution, enabling efficient motor operation with enhanced power density.

Manufactured from high-grade NdFeB (Neodymium Iron Boron) material, our arc magnets are precision-cut into curved profiles and magnetized to match specific pole configurations. Protective coatings (Ni-Cu-Ni, epoxy, or custom plating) ensure corrosion resistance and long-term reliability in demanding operating environments. The arc geometry allows seamless integration into rotor assemblies, supporting both surface-mount and internal-mount motor designs.
