PROCEDE DE FABRICATION D'AIMANTS PERMANENTS POUR UN MOTEUR ET MOTEUR CORRESPONDANT

摘要

The method involves introducing ferromagnetic particles powder (26) into a molding die that is formed in a rotor and a stator of a motor. The ferromagnetic particles powder is compressed in the molding die. The ferromagnetic particles powder is sintered to form a solid body. The solid body is magnetized. The ferromagnetic particles powder is subjected to a magnetic orientation during compression of the ferromagnetic particles powder, where the magnetic orientation and the magnetization of the body are carried out by magnetizing coils (32) placed around the molding die. An independent claim is also included for a motor.
