Multi-polarized magnet rotor

Injection-molded assemblies in which polar-isotropic magnets and shafts are joined together by injection molding to obtain a complete rotor are commonly used for motor rotors. The production process is to make the magnetic ring first, and then injection mold the inner diameter side of the magnetic ring to become an integrated motor rotor assembly. Different shapes of injection-molded rotor assemblies can be produced according to customers' requirements.
