    摘要： A rotor is provided for an electric motor. The rotor shaft is located within a central opening of the rotor core. The central opening is sized larger than the rotor shaft such that a circumferential gap exists between the rotor core and the rotor shaft while the shaft is located by protrusions in the central opening of the rotor core. The circumferential gap is filled with a resin.

    摘要： The present disclosure relates to a motor. The motor can include a stator defining an interior space, a rotor disposed in the interior space of the stator. The rotor can include a body defining a structure and a plurality of magnets disposed in the plurality of cavities. In some embodiments, the structure defines a plurality of cavities in the body of the rotor, the plurality of cavities includes at least a first cavity and a second cavity, the first cavity is spaced radially outward from the second cavity, and a thickness of the first cavity is larger than a thickness of the second cavity. In some embodiments, at least some of the cavities of the plurality of cavities have a magnet from the plurality of magnets disposed therein.

    摘要： A method for manufacturing a multicomponent permanent magnet, and a multicomponent permanent magnet are proposed. The multicomponent permanent magnet has a first permanent magnet having a R-T-B-composition, wherein R is at least one selected from the group consisting of Y, Ce, La, Pr, Nd, Sm, Eu and Gd and T is one or more transition metal elements including Fe; and a second permanent magnet having a R-T-B-composition, wherein R is at least one selected from the group consisting of Y, Ce, La, Pr, Nd, Sm, Eu and Gd and T is one or more transition metal elements including Fe, the second magnet including at least one of a heavy rare earth element (HRE) and an increased amount of Ce and/or Co, the second magnet having different magnetic properties, in particular a higher coercivity, than the first magnet. The first magnet and the second magnet are connected mechanically, wherein the connection is electrically conductive with an adjusted electrical resistivity.
