Multipole ring magnets

Multipole ring magnets are a more desirable solution to the permanent magnet motors and magnetic coupling devices in comparison with conventional splicing several arc magnets. It can be classified to isotropic type and anisotropic type. Isotropic type is generally refers to ring-shaped bonded magnets with multipole. Anisotropic type, or multipole sintered ring magnet, has always been touted as a high-end product.
