  • Centrifugal water pump having polar anisotropic magnetic ring
    Publication number: 20070007840
    Abstract: A centrifugal water pump comprises a rotor having a polar anisotropic magnetic element. Magnetic force lines are centrally distributed at the inner or outer surface of the polar anisotropic magnetic ring to obtain high magnetic flux density and shortest magnetic line path to increase output efficiency when the polar anisotropic magnetic ring is coupled to the stator. The polar anisotropic magnetic ring is made of ferrite; thus rust and chemical erosion of the polar anisotropic magnetic ring can be prevented when the magnetic ring is used in water and no additional water-proofing element is required.
