Neodymium Arc Magnets
Properties
- Material Composition: Made primarily from neodymium (Nd), iron (Fe), and boron (B), these magnets belong to the rare-earth magnet family.
- Magnetic Strength: They are among the strongest permanent magnets available, often rated with a maximum energy product (BH max) ranging from 30 to 52 MGOe (Mega Gauss Oersteds).
- Shape and Size: Typically, they are cut into a curved segment shape, which allows them to fit into cylindrical or circular applications, maximizing magnetic efficiency.
- Magnetic Field Orientation: The orientation of the magnetic field is crucial; arc magnets are often magnetized through the thickness, enhancing their performance in rotational applications.
We sell all grades of neodymium magnets, custom shapes, sizes, and coatings.
Magnetic Product Description:
Arc magnets are a very common shape among NdFeB magnets. These magnets are usually used in motor products. Because of its special shape and strong magnetic force of NdFeB magnets, many customers like this magnet very much.
Uses For Our Arc Magnets:
Electric Motors: Used in brushless DC motors, they increase efficiency and power output in applications such as electric vehicles and robotics.
Generators: In wind turbines and other power generation equipment, arc magnets improve energy conversion efficiency.
Magnetic Couplers: In industries where fluid transfer occurs, these magnets can couple two shafts without physical contact, minimizing wear.
Magnetic Separators: In recycling and manufacturing, arc magnets can effectively separate ferromagnetic materials from non-magnetic materials.
Magnetic Sensors and Switches: Used in a variety of electronic devices, they help detect position and motion.
FAQ
- Stronger Magnetic Field: The curve helps create a more focused and powerful magnetic field, especially useful in motors and generators.
- Fit for Rotational Systems: Their shape fits perfectly in cylindrical designs, which is ideal for rotating parts, ensuring consistent performance.
- Space Efficiency: Arc magnets take up less space while providing strong magnetic force, important for compact devices.
- Higher Torque: The curvature improves interaction with other components, leading to better torque and power output in electric motors.
- Easy Integration: Their shape allows for simpler assembly in various applications, like magnetic couplings.
- Cost-Effective Magnetization: The design allows for more efficient magnetization, reducing production costs.
- Alloy Production: Melt neodymium, iron, and boron together to form an alloy.
- Powdering: Grind the cooled alloy into a fine powder.
- Pressing: Press the powder into an arc-shaped mold.
- Sintering: Heat the pressed mold in a vacuum to solidify the magnet.
- Machining: Machine the magnet for precise dimensions.
- Magnetization: Expose it to a strong magnetic field to align the magnetic properties.
- Coating: Apply a protective layer to prevent corrosion.
The demagnetization of permanent magnets varies based on several factors:
- Temperature: High temperatures can weaken magnets, especially neodymium magnets, at around 80-200°C.
- External Magnetic Fields: Strong external fields can quickly demagnetize a magnet.
- Mechanical Stress: Dropping or damaging a magnet can cause it to lose strength.
- Time: While they can last decades in stable conditions, gradual loss can occur over years.
