Radially magnetized multipole ring magnets offer several advantages for electric motors, including easy installation to the rotor shaft, uniform magnetic flux density, and flexible pole number. These features make them a versatile and reliable choice for various BLDC motor designs, allowing for optimal performance and precision.
Radially magnetized ring magnets showcase a unique magnetization pattern that resembles an assembly of multiple arc segment magnets mounted on a rotor. Often referred to as radial ring magnets or radial magnet rings, these magnets offer the advantage of easy installation and deliver superior performance compared to traditional configurations. Their innovative design makes them a practical and efficient solution for various applications.
Anisotropic magnets, which have a preferred magnetization direction, can also be radially magnetized in special patterns if proper radial orientation is applied during the pressing. This allows for skew magnetization to be achieved on a radial ring magnet, reducing cogging torque in motor applications. Both sintering and hot-pressing techniques can be used to achieve radial orientation.
As a counterpart, polar-anisotropic ring magnets feature an orientation pattern of Halbach array. This type of multipole ring magnet exhibits higher flux density than radial ring magnet, but is generally more expensive to manufacture.
Neodymium magnets can be classified as anisotropic or isotropic. Anisotropic magnets have a preferred magnetization direction, while isotropic magnets can be magnetized flexibly in any direction. Sintered neodymium magnets are typically anisotropic, offering higher flux density, whereas multipole ring magnets made of bonded neodymium magnets are isotropic and commonly used in hall sensor applications.
While the magnetization pattern of anisotropic magnets is predetermined during the pressing process, the pole number is later determined by magnetizing coils.
As advancements in artificial intelligence and automation technology continue to progress, the demand for high-precision electromechanical products is growing rapidly. In the case of electric motors, such as BLDC motors in home appliances and servo motors in industrial robots, miniaturization, lightweight design, and high efficiency have become significant industry trends.
As a China-based sintered neodymium magnet manufacturer and radially magnetized ring magnet supplier, we specialize in producing key materials for high-performance motors with compact designs. Radially magnetized neodymium magnets are primarily utilized in high-performance permanent magnet motors and sensors, offering benefits such as high precision, stable operation, and low noise. As radial magnetization technology evolves, both the price and performance of these magnets are expected to further align with market demands, making them an increasingly attractive option for a wide range of applications.
