This is a high quality and high performance motor magnetic ring, the material is injection molded ferrite, 12 poles magnetized inside diameter, the surface magnetic field strength is more than 1500 gauss, it is suitable for brushless DC fan ceiling fan motors, external rotor axial fan motors, it can be customized according to your dimensions, the number of poles, and the magnetic performance, please feel free to consult with us for the existing specifications and quotations.
Both ferrite and NdFeB can be used for magnetic ring multi-pole magnetization. Magnetic ring multi-pole magnetization can be divided into magnetic ring external charging and magnetic ring internal charging. External magnetization (strong magnetism of outer diameter) means that the outer surface of the ring is filled with magnetic poles, which is generally used for inner rotor motors. Inside magnetization (strong inner diameter magnetism) means that the inner surface of the ring is filled with magnetic poles, which is generally used for outer rotor motors.
