Description of NdFeB Arc Magnets
NdFeB (Neodymium Iron Boron) magnets, when shaped into arcs, are known as NdFeB arc magnets. These magnets maintain the strong magnetic properties of neodymium magnets but are designed to provide a magnetic field in a segment of a circle rather than a full disc or block shape. NdFeB Arc magnets are often used in applications where a partial magnetic field is required, or where space constraints dictate the use of a non-standard shape.
NdFeB arc magnets are a specialized form of neodymium magnet, offering a partial magnetic field that is tailored to specific application needs. Their design allows for efficient use of space and magnetic field strength, which is critical in high-performance applications.
Preparation process of NdFeB arc magnets
Processing technology:
Powder metallurgy: After mixing the raw material powders, high-performance NdFeB magnets are prepared through pressing, sintering and other processes.
Isostatic pressing: Through isostatic pressing technology, the density of the magnet is ensured to be uniform and its mechanical properties are improved.
Heat treatment: Through high-temperature annealing treatment, the grain structure of the magnet is optimized and its magnetic properties are improved.
Machining: Through high-precision machining, the magnet is processed into the required arc shape.
Features of NdFeB arc magnets
Shape: Arc magnets are typically a segment of a circle, with the arc angle varying depending on the application. Common angles range from 30 degrees to 180 degrees or more.
Strength: Like other neodymium magnets, arc magnets are extremely powerful and have a high remanence (residual magnetism) and coercivity (resistance to demagnetization).
Material: They are made from the NdFeB alloy, which is known for its high magnetic strength and durability. The material is usually coated to protect against corrosion.
Temperature: NdFeB arc magnets have a maximum operating temperature that can range from around 80°C to 150°C, depending on the grade and treatment of the magnet.
Applications of NdFeB arc magnets
1. Motors and Generators: Arc magnets are used in brushless electric motors, including those in electric vehicles, wind turbines, and other types of generators. They provide a magnetic field for the motor to interact with the electrical windings.
2. Actuators: They are used in various types of actuators for precision positioning and control.
3. Magnetic separators: Arc magnets can be part of systems designed to separate magnetic materials from non-magnetic materials in processing and recycling applications.
4. Magnetic resonance imaging (MRI): In medical equipment like MRI machines, arc magnets can be used to create the strong magnetic fields needed for imaging.
Magnetization direction
Arc neodymium magnet can be magnetized as width, thickness,diametrical-N-pole on outside face,diametrical-N-pole on inside face, and others for customization. See below for details:
Testing and Quality Control of NdFeB arc magnets
Dimensional accuracy: The dimensional tolerance of the arc magnet is strictly controlled within ±0.05mm to ensure high precision.
Surface quality: The surface is smooth, without scratches, cracks, oxidation and other defects, and can be polished to further improve the surface finish.
Performance testing: The finished product is tested for magnetic properties (such as remanence, coercive force, maximum magnetic energy product, etc.) and mechanical properties to ensure that it meets the standards.
