The output of sintered NdFeB magnets in China has exceeded 80% of the world’s total output. Permanent magnet motors are an important field for the application of rare earth permanent magnets. In recent years, with the development of permanent magnet motor design and manufacturing technology and control technology, rare earth permanent magnet motors have been widely used in the fields of automobiles and CNC machine tools. Now let’s take a look at the advantages of the radiation (multi-pole) magnetic ring of the sintered NdFeB magnet used in permanent magnet motors. NdFeB Radiation Oriented Annular Magnet

Importance Note: Please leave a comment about N pole outside or inside. if not, we will send radomly.
radial ring magnets features:
1, Radial maximum energy product can reach 240 ~ 400kJ/m3 high magnetic.
2, It can be manufactured to facilitate bonding, the long dimension of the annular magnet assembly.
3, you can easily change the number of poles and the magnetic declination simply by the change of the magnetic coil.
4, Inner and outer circumferences monopole with magnetic as you required.
5, Rectangular wave, trapezoidal wave, sin function with magnetic waves. (Function waveform, please contact us)
6 trails, thin-walled, long size (for example: the outer diameter of 5mm wall thickness of 0.5mm, length 80mm) contributes to the miniaturization of the motor.

Uni Pole Radiation Oriented Annular Magnet

Up until recently, full magnetic rings (FMR) made of separate magnets conjoined together to create the desired ring shape, were the only solution for applications requiring circular-shaped multi-pole magnets.Now, a new technology powered by MPCO has enabled for the creation of a super strong, durable single-cast radially magnetized ring magnet. radiation ring magnet use for automotive electric power steering system, quiet, smooth sense of control, and easier to install. AC servo motor, DC motor can achieve a quiet and smooth operation of this feature, it is also used for the precision operation of the robot is required.
