Radial magnetic ring, also known as radial ring magnets, have their strong magnetic surfaces on the side of the ring magnets, and are mostly used in toys, motors, sensors, and Hall induction fields. Today, I will tell you about this radial ring in detail. Common materials, specifications, and magnetization diagrams of magnets.
What are the materials of radial ring magnets?
At present, NdFeB and ferrite are mainly used on the market, including sintered NdFeB radial ring magnets, injection molded NdFeB radial ring magnets, sintered ferrite radial ring magnets, and injection molded ferrite diameter ring magnets. For ring magnets, you can choose the right material according to your product needs.
Schematic diagram of the magnetization of a radial ring magnet

The above picture mainly shows the magnetization method of radial multi-pole ring magnets. The magnetization method of ordinary radial ring magnets is as shown in the figure below.

Main applications of radial ring magnets:
The rotors of brushless DC motors and permanent magnet synchronous motors are the main applications. They are installed on the motor shaft or rotor yoke. The radial magnetic field they generate interacts with the stator current to efficiently produce torque.
In addition, sensors, magnetic couplers, and magnetic bearings also use radial ring magnets.
The above is the application, common materials and magnetization diagram of radial ring magnet. Customers who need radial ring magnet and radial multipole ring magnet are welcome to inquire.
