Ferrite arc magnets, also known as ceramic arc magnets, are widely used in applications requiring strong, durable magnets at an affordable cost. These magnets are specifically designed for motor and generator assemblies due to their arc shape, which aligns perfectly with rotors and stators.
Material Composition: Ferrite magnets are made from iron oxide mixed with strontium or barium carbonate, offering a cost-effective yet robust magnetic material.
Durability: They are highly resistant to corrosion and can operate in harsh environments without additional coatings. Their resistance to demagnetization and environmental factors makes them ideal for long-term use.
Magnetic Properties:
Moderate strength compared to rare earth magnets.
High coercivity, which means they retain their magnetism well under external magnetic fields.
Applications:
Electric Motors and Generators: Used in rotor or stator assemblies for consistent performance in AC and DC motors.
Household Appliances: Incorporated in fans, washing machines, and other devices.
Industrial Machinery: Applied in magnetic couplings and sensors.
Shapes and Customization: These magnets can be custom-sized and shaped for specific industrial needs, making them versatile for various applications.
The image provided illustrates a set of ferrite arc magnets with their characteristic curved shape, often used in motor assemblies. This setup emphasizes their industrial relevance and precision engineering.
