1.SDM Radially Oriented Ring Magnet

The radially oriented ring magnet means that the magnetization direction of the ring magnet is in a radial pattern through radial direction. Even if many sales in the magnet industry unable to distinguish radially oriented ring magnet and diametrically magnetized ring magnet until now.

 

For sintered rare earth 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.

The advantages of radially oriented ring magnet

• The assembling process of motor assembly will be much easier than gluing arc segments magnets on a ring, also the assembling cost.


• 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.


• Improve the utilization rate of raw material.


• Modify the distribution of surface magnetic field, then motor powder will increase more than 15%.

Applications of radially oriented ring magnet

How to make radially oriented ring magnet?

 

The radially ring magnet family includes sintered rare earth magnet, sintered ferrite magnet, hot-pressed/hot-deformed magnet and bonded magnet. Different kinds of magnet have its own mode to make radially oriented ring magnet.

 

Sintered rare earth magnet:

 

Radially oriented ring magnet usually refers to sintered magnet. The sintered rare earth magnets can be divided into NdFeB and SmCo. The orientation system for radial oriented sintered rare earth magnet is more complicated than simple sintered one to apply the radially orientation magnetic field during the molding process. The ring blanks with radially oriented can be magnetized into multi-polar ring magnet. For sintered rare earth magnet, the customers should bear the cost of orientation coil and magnetization fixture, and therefore the development cost of this kind of magnet is very expensive.

 

 

 

Isotropic bonded magnet:

 

The isotropic magnet could be magnetized in any direction with suitable L/D ratio can be magnetized into radially-oriented ring magnet due to the restrictions of magnetization fixture.

Anisotropic injection molded magnet:

 

The radially oriented magnet is the most complex type among the whole anisotropic injection molded magnets. How to guide the magnetic circuit in into the cavities is the most critical factor. The radially oriented anisotropic injection molded ring magnets are usually made by electromagnetic orientation technology. Unlike the simple permanent magnet orientation, magnets made by electromagnetic orientation will be demagnetized before die sinking, then re-magnetize into multi-polar according to customer's requirement. 

Hot-pressed/hot deformed magnet:

 

The hot-pressed magnet is full-density isotropic magnet, and full-density anisotropic magnet for hot-deformed magnet. The hot-deformed technology has already became a practical method to manufacture the radially oriented ring magnet.
