Large Neodymium Arc Magnets – China Permanent Magnet Factory | Fullzen

Short Description:

Here are some additional details about large neodymium arc magnets:

  1. Shape and dimensions: Large neodymium arc magnets can come in various shapes and sizes depending on the specific application requirements. The most common shape is a segment of a circle or arc, with angles ranging from 30 to 180 degrees. The size of the magnets can range from a few millimeters to several centimeters in diameter.
  2. Magnetic strength: Large neodymium arc magnets have a high magnetic strength, which makes them suitable for industrial and scientific applications that require strong and precise magnetic fields. The magnetic strength can range from a few hundred Gauss to several Tesla, depending on the size and shape of the magnet.
  3. Magnetization direction: Large arc shaped neodymium magnets can be magnetized in different directions depending on the specific application requirements. The most common magnetization directions are radial, tangential, and axial.
  4. Manufacturing process: Large neodymium arc magnets are typically manufactured using a process called sintering, which involves compacting neodymium powder under high pressure and temperature. The sintered neodymium is then cut and shaped into the desired arc shape.
  5. Applications: Large neodymium arc magnets are used in various industrial and scientific applications that require strong and precise magnetic fields. Some common applications include motors, generators, magnetic sensors, magnetic separators, magnetic bearings, and magnetic resonance imaging (MRI) machines.
  6. Handling and safety: Large neodymium arc magnets can be very strong and can pose safety hazards if not handled properly. It is important to follow safety guidelines when handling and assembling large neodymium arc magnets, including using protective gear and avoiding exposure to strong magnetic fields.

    Magnetic Product Description:

    This neodymium magnetic disc has a diameter of 50mm and a height of 25mm. It has a magnetic flux reading of 4664 Gauss and a pull force of 68.22 kilos. 

    Uses For Our Strong Rare Earth Disc Magnets:

    Strong magnets, like this Rare Earth disc, project a powerful magnetic field that is capable of penetrating solid materials such as timber, glass or plastic. This ability has practical applications for tradespeople and engineers where strong magnets can be used to detect metal or become components in sensitive alarm systems and security locks.


    What is cogging?

    Cogging, also known as detent or magnetic cogging, refers to an undesirable phenomenon in motors and generators where the rotation experiences a jerky or uneven motion due to the interaction between the permanent magnets and the teeth of the stator or rotor. This phenomenon is most commonly observed in brushless DC motors, permanent magnet synchronous motors (PMSMs), and other types of motors that utilize permanent magnets.

    Cogging is caused by the attraction or repulsion between the permanent magnets on the rotor and the teeth or slots on the stator. As the rotor rotates, it encounters these teeth, and due to the fixed positions of the magnets and teeth, the magnetic forces can cause the rotor to experience varying levels of resistance or attraction at different points of its rotation. This results in a pulsating or uneven torque output, leading to jerky motion and reduced overall smoothness of operation.

    What are the advantages of custom arc magnets?

    Custom arc magnets offer several advantages compared to standard or off-the-shelf magnets, especially when it comes to meeting specific design, performance, and application requirements. Here are some of the key advantages of using custom arc magnets:
