Neodymium arc magnets Description

Neodymium arc magnets, or neodymium segment magnets, can be seen as a part of neodymium ring magnets or neodymium disc magnets. They are made of high-quality neodymium magnets containing the elements neodymium, iron, and boron. NdFeB magnets are permanent magnets and the most widely used type of rare earth magnets. Neodymium arc magnets are mostly used in voice coil motor, permanent magnet motors, generators, wind turbines, torque couplings, and other applications.

Stanford Magnets specializes in manufacturing and supplying neodymium arc magnets applied in various industrial applications. We have advanced technology, rich experience, and professional engineering technicians in this field.

Neodymium arc magnets Key Characteristics

• Strong Magnetic Field: Neodymium arc magnets have one of the strongest magnetic fields among permanent magnets, making them highly efficient in applications requiring a compact and powerful magnet.
• Custom Shapes: The arc shape is tailored to fit into motors or generators, allowing for a more efficient magnetic field distribution around the rotation axis.
• High Coercivity: They have a high resistance to demagnetization, maintaining their magnetic properties under various conditions.
• Temperature Sensitivity: While neodymium magnets are known for their strength, their magnetic properties can decrease at high temperatures. Various grades are available to withstand different temperature ranges.
• Corrosion Resistance: Arc magnets are often coated to prevent corrosion. Common coatings include nickel, zinc, and epoxy.

Neodymium arc magnets Applications

• Electric Motors and Generators: The arc shape is ideal for the circular configurations of electric motors and generators, contributing to efficient energy conversion.
• Wind Turbines: Used in the generators of wind turbines to help convert wind energy into electrical energy.
• Magnetic Bearings: Employed in high-precision magnetic bearings for reduced friction and wear in various machinery.
• Audio Equipment: High-quality speakers and headphones sometimes use neodymium arc magnets for their powerful and precise magnetic fields.

Neodymium arc magnets Handling and Safety

Handling neodymium arc magnets requires caution due to their strong magnetic pull, which can cause injury or damage if the magnets snap together unexpectedly. Protective gear should be worn to prevent pinching or bruising. Additionally, these magnets should be kept away from electronic devices and magnetic media to avoid interference or damage.

Neodymium arc magnets Customization and Manufacturing

Manufacturers can customize neodymium arc magnets in terms of size, magnetic grade, and coating to suit specific applications. The manufacturing process involves sintering the NdFeB alloy into a solid block, machining it into the desired arc shape, and then applying a surface treatment to prevent corrosion. Precision is key, as the arc segments must fit together perfectly in their application to achieve the desired magnetic performance.
