25-35In general, they provide high performance and cost-effective alternatives to arc/segment magnets. According to different production processes, radially oriented NdFeB ring magnets include sintered NdFeB ring magnets, bonded NdFeB ring magnets and hot-pressed NdFeB ring magnets.
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.

The main advantages of radiating magnetic rings include:
1, the radiation ring is an integral magnetic ring, the dimensional accuracy is better controlled, the assembly process is more simplified;
2, the surface field is sinusoidal waveform, uniform distribution, small transition area between magnetic poles, so the motor is stable and low noise;
3, the magnetization mode and magnetic field distribution are diverse, can be unipolar radiation, multi-pole direct charge and multi-pole oblique magnetization, magnetic circuit design is more flexible.
Radiating magnetic ring is a kind of circular permanent magnet with special orientation. It is magnetized along the radial circumference of the magnetic ring. It can be widely used in servo motor, magnetic drive, magnetic bearing and sensor.
