It is accurate to contact the Chinese manufacturer of courage magnets when purchasing motor multipole ring magnets. Our company has many sintered ferrite/injection ferrite/injection neodymium iron boron/bonded neodymium magnet molds, samples, and today we bring you a radial 4-pole rotor magnetic iron ring with an inner hole of 8mm. The injection ferrite material has an outer diameter of about 45mm, which is customized by our company for customer mold opening. The surface magnetic strength is around 1400 Gauss, If you have any purchasing needs for axial or radial motor multipole magnetic rotors, please leave your contact information on our website to let us know your requirements.
