Multi Poles Ring

The advantages are significant:

• Motor assembly is made much easier; installation of one or more rings versus gluing arcs into place.
• Radial sintering assures no weak spots.
• Magnets are multi-poles thus the ring does not compromise the magnetic properties
• The radial orientation results in a super strong magnet by virtue of superior metallurgy developed specifically to BE radially oriented.

Technology:

Hot pressing is a new method of producing sintered NdFeB magnets. This process consists of combining base powders, hot pressing the resulting material, and then baking or sintering the resulting ring to achieve a radially magnetized product. This new technology improves the magnetic flux which in turn provides better efficiency and performance.

Radial Dual-Pole Cylindrical Magnet	High-Grade Radial Multi-Pole Ring

Available Dimension:

Below are the mould we have in stock. If you choose one of them, you will not pay for the mould fee. but you should have to pay for the Magnetic fixture fee.

You can use the mould as above and the ones with uni pole radial ring mgnets, meanwhile AOMAG have extral mould & magnetic fixture for Ndfeb Sintered multi poles ring magnets with diametrically magnetized as below:

The advantages of radially oriented ring magnet

1. The assembling process of motor assembly will be much easier than gluing arc segments magnets on a ring, also the assembling cost.
2. The assembling accuracy of radially oriented ring magnet will be much higher than traditional multi-arc assemblies, then improve the dynamic balance of the motor.
3. Improve the utilization rate of raw material.
4. Modify the distribution of surface magnetic field, then motor powder will increase more than 15%.
