Introduction of Radial 4 Pole Ferrite Magnet Rotors

The 4-pole ferrite rotor, that is, there are 2 N poles and 2 S poles on the ferrite ring magnet. The hole in the middle of the magnet is used to install the shaft, mainly for radial magnetization. The 4-pole ferrite magnet is introduced below. The magnetization method of the rotor and the magnetization diagram, application, and some of our company's size specifications.

How to magnetize a 4 pole ferrite rotor ring? 

First, a ring-shaped ferrite is produced, and then the ferrite is placed in the electromagnet environment as shown in the figure, energized to generate a magnetic field, and a magnetic circuit is formed as required. Finally, the ferrite is magnetized into a quadrupole magnetic ring. 6-pole, 12-pole and other magnetic rings, the principle is the same, but the number of magnetized poles changes.
