What is radially oriented ring magnet ?

1: What is radially oriented ring magnet ?

Radial ring is whole radial ring magnet, it can be magnetized as multi-pole, skewed and uni-pole magnetized. The ring mainly used as induction magnet for motors.It can improve the motors` performance and property. It is the future development tendency of Motor Magnets.

PUFEITE Magnetics co;ltd is one of the best Sintered Ndfeb Ring Magnet manufacture in China.

For Sintered NdFeb Magnet , the traditional method to make multi-polar magnet is often by placing arc segments magnets on a ring shape . the intricate process and uneven distribution of magnetic field strength are always restrict the development of this method . the biggest role of radially oriented technology is helping anisotropic magnet to achieve multi-polar magnetization ,and extend its application in various areas .

2: Different ways of magnetizing

The radially oriented ring magnet means that the magnetization direction of the ring magnet is in a radial pattern through radial direction , the popular poles include : 2pole , 4 poles, 8 poles, 10 poles , 12 poles ect , the number of poles and the skew angle were decided by the magnetizing tooling.

Sintered Polar anisotropic Ring, By this technology, surface magnetic flux can reach top level, about 50%-100% higher than the Arc magnets and radial ring Magnets, it can remarkably raise the efficiency of Motors, and It also helps motor to be light-weight and save raw materials, these make it to be a good choice for high-performance motors.

4: What the advantages of radially oriented ring magnet

1. l Easier for assembly process compared with gluing several segments magnets and thus reduce assembly cost.
2. l Improve utilization rate of raw material.
3. l Excellent dimensional accuracy which will substantially enhance dynamic balance of the motor.
4. l Highly flexible magnetization patterns, controllable waveform and magnetic field strength which will reduce cogging torque and motor noise.
5. Available for N35-N50, N35M-N50M, N35H-N48H, N35SH-N45SH, N35UH-N40UH, N28EH-N33EH.
