Nowadays ,the process of radial NdFeB ring is stability through batch testing,and suitable for industrial

scale production, our company has been formed the mature radial ring magnet. Ring Magnet Magnetized

in Radial Direction is developed successfully which is using the shaping method by new multipole 

radiation orientation, and meets different requirements of permanent motors. Fundamentally changed the

past situation that radial ring of magnet only relied on the magnetic tile assembly, greatly improve the

performance of the motor.

Sen Long has developed a unique hot extrusion process to produce radially oriented anisotropic Nd-Fe-B

ring magnets.A variety of magnetic pole distribution. The magnetic ring magnet has the highest level of energy,

high heat resistance,it does not occur corrosion from internal of the product.

Product Features

Highest energy product of 240~400kj/m3（30~40MGOe)in truly radial direction

Full rings with a wide range of diameters(min.OD5mm)and lengths (max.80mm) for easy assembly

Various magnetization patterns possible(multi-pole to uni-pole,various skew angles)by the design of magnetizing fixtures

Precise magnetization waveform control(such as rectangular,trapezoidal,sinusoidal)for high power or low cogging

High heat resistant grades(up to 180 deg.C)available

Inherently better corrosion resistance due to the absence of internal porosity
