Large Arc Magnets
Neodymium arc magnets, also known as neodymium segment magnets, are a type of permanent magnet made from an alloy of neodymium, iron, and boron (NdFeB). These magnets are specifically shaped in segments of a circle, resembling arcs, which makes them ideal for applications that require a curved magnetic field. Arc Ndfeb magnets/tile Ndfeb magnets are commonly used on the rotors and stators of motors and generators, and where magnets are required to form around cylinders. Common surface finishes are nickel/zinc plated and black epoxy coating.

Characteristic:

Temperature resistance - Magnet Grade N42, maximum operating temperature is 80°C/176°F. Temperature is the first factor you must consider when choosing a magnet, to ensure you choose the suitable magnet, please contact our engineers for details.
Premium Coating - This Ndfeb magnet is protected by a corrosion-resistant nickel-chromium alloy coating, creating a high-quality silver appearance that won't rust or scratch.
The nickel-cobalt coating is one of the most popular surface treatments for NdFeB magnets. We can provide other coatings. Such as nickel copper nickel, epoxy resin, zinc, gold, and so on.
- Composition: Neodymium arc magnets are composed of neodymium, iron, and boron, providing them with strong magnetic properties. They are part of the rare earth magnet family and are recognized for their high energy density and coercivity.
- Shape: The arc shape allows these magnets to fit around cylindrical surfaces, making them suitable for use in motors and generators where space is limited.
- Performance: They exhibit superior magnetic strength compared to other types of magnets, enabling them to perform effectively in demanding applications.
Applications
Neodymium arc magnets are widely used in various industries due to their high performance:
- Electric Motors: Integral components in motor rotors, enhancing efficiency and power output.
- Generators: Used in wind turbines and other energy conversion systems to generate electricity.
- Magnetic Pumps: Facilitate smooth motion and power transfer in industrial applications.
- Voice Coil Motors: Commonly found in audio equipment and other electronic devices.
