Manufacturer Customized Radial Magnetized Ring Neodymium Magnet


Radial magnetized ring neodymium magnets are a specialized form of neodymium iron boron (NdFeB) magnets, designed with their magnetic fields oriented in a radial pattern from the center to the outer edges, rather than axially magnetized from one flat end to the other. This unique magnetization provides distinct advantages for specific applications. Here are the key functions and features of radial magnetized ring neodymium magnets:


  1. Electric Motors and Generators: These magnets are particularly suited for use in brushless DC motors (BLDC) and generators. The radial magnetization allows for a more efficient magnetic field distribution, improving the performance of the motor or generator.

  2. Magnetic Bearings and Couplings: Radial magnets can be used in magnetic bearings and couplings for non-contact operations, which reduces wear and increases the lifespan of these components.

  3. Sensors: In applications where a uniform magnetic field is required in a circular pattern, radial ring magnets provide an ideal solution.

  4. Magnetic Gear: For applications requiring magnetic gears, the radial magnetization of these magnets allows for efficient transmission of torque across non-contacting elements.


  1. Uniform Magnetic Field: One of the most significant features of radial magnetized ring neodymium magnets is their ability to create a uniform magnetic field along the circumference of the ring, which is essential for certain high-precision applications.

  2. High Magnetic Strength: As with other neodymium magnets, these radial rings offer very high magnetic strength, making them suitable for applications where strong magnetic forces are required.

  3. Compact Design: The ring shape and radial magnetization allow for compact designs in applications like electric motors, where space is often at a premium.

  4. Customizable: Radial ring magnets can be customized in terms of diameter, thickness, and magnetization pattern to suit specific application requirements.

  5. Corrosion Resistance: With proper coating (such as nickel, zinc, or epoxy), these magnets can resist corrosion, which is crucial for applications exposed to harsh environments.

  6. Temperature Sensitivity: While neodymium magnets have high magnetic strength, they are also sensitive to temperature. Radial magnetized ring neodymium magnets may require stabilization or special grades to operate at elevated temperatures without losing magnetic properties.

Radial magnetized ring neodymium magnets represent a specialized solution for applications requiring a circular magnetic field with high strength and precision. Their design and magnetization pattern make them indispensable in modern engineering and technology fields, offering unique advantages over traditional axially magnetized magnets.
