Abstract[English]
A permanent magnet rotor can include a rotor body and at least one magnet. The rotor body can include at least one rotor cavity. The at least one magnet includes, in part, Mn-Bi particles and the at least one magnet can be either a sintered magnet or a polymer bonded magnet. The at least one magnet can be located, at least partially, in the at least one rotor cavity. Further, the at least one magnet can be installed in the at least one rotor cavity after forming the at least one magnet or the at least one magnet can be formed in the at least one rotor cavity using a mold. Moreover, the polymer bonded magnet can include a composite of polymer matrix and Mn-Bi particles.[French]
La présente invention concerne un rotor à aimants permanents qui peut comprendre un corps de rotor et au moins un aimant. Le corps de rotor peut comprendre au moins une cavité de rotor. Le ou les aimants comprennent, en partie, des particules de Mn-Bi et le ou les aimants peuvent être soit un aimant fritté, soit un aimant lié par polymère. Le ou les aimants peuvent être situés, au moins partiellement, dans la ou les cavités de rotor. En outre, le ou les aimants peuvent être installés dans la ou les cavités de rotor après la formation du ou des aimants ou le ou les aimants peuvent être formés dans la ou les cavités de rotor à l'aide d'un moule. Enfin, l'aimant lié par polymère peut comprendre un composite de matrice polymère et de particules de Mn-Bi.
