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....
This is a 4-pole rotor magnet. The material is injection-molded NdFeB, and the magnetization direction is radial. It was photographed by Courage Xiaofu. From the appearance, you can see the difference from injection-molded ferrite. The surface is shiny. Luminous NdFeB magnetic powder,...
