A radially magnetized ring magnet has a special magnetization pattern in which the north and south poles are distributed in the inner or outer diameter. To simplify, it is also called radial ring magnet or radial magnet ring.
Anisotropic magnets have a preferred magnetization direction, while isotropic magnets can be magnetized flexibly in any direction. Generally, sintered neodymium magnets are anisotropic and bonded neodymium magnets are isotropic. For sintered neodymium magnets, the magnetization pattern has to be predetermined by orientating the magnetic domains during the pressing. Therefore, it’s also called radially oriented ring magnet. On the other hand, bonded magnets can be magnetized in various patterns by custom magnetizing fixtures.
Not only Isotropic magnets can be magnetized in radial direction, anisotropic magnets can also be radially magnetized even in special pattern if proper radial orientation is applied during the pressing. For motor application, skew magnetization can be achieved on a radial ring magnet to reduce cogging torque.
With the development of artificial intelligence and automation technology, there are more and more high precision electromechanical products. For electric motors such as permanent magnet motor in home appliance, servo motor in industrial robots, miniaturization, lightweight and high efficiency have become a big trend of the industry. Tengye Magnetic is a China-based sintered neodymium magnet manufacturer and radial ring magnet supplier. Radially magnetized neodymium magnet is a key material for high performance motors with small body. At present, radial ring magnets are mainly used in high performance permanent magnet motors and sensors, which have the advantages of high precision, stable operation and low noise. As the radial magnetization technology continues to develop, the price and performance will continue to meet the market demand.
