Uniform Magnetic Flux Distribution
The arc-shaped geometry is designed to fit the rotor circumference and form a continuous magnetic circuit when assembled with multiple segments. This structure helps distribute magnetic flux more evenly across the rotor surface and supports balanced magnetic field generation during rotation.
Stable Torque Generation
Consistent magnetic field distribution allows the rotor to interact with stator windings in a controlled manner, helping maintain stable torque output in motor and generator applications operating under continuous rotational load.
Batch Consistency & Magnetic Stability
Manufactured from sintered ferrite material with controlled magnetic properties, each production batch undergoes magnetic flux verification to maintain consistency between segments. This helps reduce magnetic variation during rotor assembly and supports stable long-term operation in rotating systems.
Resistance to Demagnetization & Long-Term Operation
The sintered ferrite material provides high coercivity, allowing the magnet to maintain magnetic strength under normal operating stress and vibration conditions. This helps reduce magnetic degradation in long-running rotary equipment such as fans, pumps, and PM generators.
Quality Control
Each Ferrite Arc Magnet 50×20×10mm is controlled through dimensional inspection of arc angle, thickness, and radius to ensure accurate fit on rotor assemblies and stable air-gap alignment during motor operation. Magnetic flux testing is performed per batch to verify consistent field strength across arc segments, ensuring uniform torque output in assembled rotors. Surface inspection is applied to detect cracks, edge chipping, and sintering defects, followed by batch sampling before shipment to maintain structural integrity and long-term production consistency.
What is a ferrite arc magnet used for?
Ferrite arc magnets are used in motor rotors and permanent magnet generators where multiple arc segments form a circular magnetic field for torque generation.
