Abstract (en)
[origin: EP2337037A2] The method involves injecting the mixture of binder in plastic state and magnetic filler, in a cavity of a molding device, where the filler is one of ferrite, neodymium-iron-bore and samarium-cobalt. The magnetic flux is generated in the cavity so that the binder passes from the plastic state to quasi-solid state. Magnetic body sections (31, 32) are realized by extracting the sections from the device. A plane surface (33) of one section is arranged in contact with a cylindrical surface (34) of another section, and the sections are connected together to form a part of a molded magnet (30).
