Magnetic Rotor
Great Wall Technology is a high-tech combo enterprise which integrates R&D, production, marketing of Ferrite magnet, NdFeB magnet, Alnico magnet, SmCo magnet, SmFeN magnet, as well as Magnetic assembly, etc.
Our Highlights
Magnetic solutions simulation, Mechanical engineering adjustment, Pilot and volume production optimization, Prototyping suggestion.
Ur Product
GWT focus on making magnetic assemblies (magnetic coupling, magnetic rotor and stator, high-precision rotor assembly etc).
Our Service
We are striving to continuously improve the magnetic quality, response rate and competitiveness.
Magnetic Rotor
We are proud to present our magnetic rotor assemblies, meticulously assembled from magnets and steel shafts to create rotor assemblies, or magnets with steel casings to form stator assemblies. These assemblies are then integrated with other parts to build motors that deliver high-speed, stable motion and generate the required torque output.
Our rotor assemblies use high-performance permanent magnets, such as neodymium (NdFeB) and samarium-cobalt (SmCo), combined with high-strength metal parts. This integration yields a compact structure, reliable performance, and efficient, stable operation, meeting the diverse needs of various applications. They are widely used in fields such as DC motors, micro motors, high-speed motors, and generators. Our rotor assemblies are a reliable choice for industrial manufacturing processes and everyday applications.
Rotor assemblies are primarily custom-designed to keep pace with market demands, evolving rapidly towards more compact sizes, lighter weights, and higher torque or speed capabilities. We provide a full range of customized services for rotor assembly products according to customer requirements, from consultation and design to prototyping and mass production.
