Motor magnetic assemblies include different kinds of permanent magnet rotor assemblies. Permanent magnet rotor assembly includes rotor core, interconnecting part and permanent magnets. The magnet inside can be a whole ring magnet or several/ a dozen of arc shaped magnets. Sintered neodymium magnets, bonded NdFeB magnets, SmCo, alnico and ferrite magnets can be used as motor magnets . The choice of magnetic materials depends on customers' requirements and applications. Neodymium iron boron magnets are usually used in high-end and high performance products and industries.

|Magnetic rotors are made up of bonded neodymiums which have high precision, high performance, good temperature stability, and excellent corrosive resistance. Therefore, such neodymium magnetic rotors are widely applied in aquatic products, rotors, water pump fittings and other fields. In aquarium circle, neodymium magnetic rotors are used for water pump fittings.|

|Ferrite magnets are cheap in cost and moderate in performance. They have good resistance to oxidation and corrosion of the environment. Ferrite magnetic motors are mostly used in some traditional industries and relatively low cost areas.|
