| 摘要 | An electrical machine is provided, in particular an electric motor having a stator and also a rotor which is mounted such that it can rotate about a rotor axis and has a rotor body, wherein permanent magnets are arranged in holders of the rotor body. The permanent magnets being composed of a mixed material, wherein the mixture is set in such a way that the mixed material has a remanence field strength Br of between 0.6 Tesla and 1 Tesla and a coercive field strength Hcj of between 1300 and 2500 KA/m. Permanent magnets or composite bodies can be arranged in holders, and the permanent magnets or composite bodies can have a contour, the cross-sectional area of said contour which is situated perpendicular to the longitudinal axis being reduced within the respective holder in the direction of the radially further outer end of said holder. | ||

| 主权项 | 1. An electrical machine comprising: a stator; and a rotor that is mounted rotatably around a rotor axis and has a rotor body; and permanent magnets formed of at least partially of a mixed material are arranged in receptacles of the rotor body, wherein the mixture is adjusted such that at room temperature the mixed material has a remanence field strength Br between 0.6 tesla and 1 tesla and a coercive field strength Hcj between 1300 and 2500 kA/m. | ||
