    摘要: An armature of the prior art has a lamination packet which leads to a high loss of magnetic flux in the lamination, since it completely encloses the magnets that are disposed in the lamination.An armature (1) of the invention comprises at least one lamination (1) that only partly encloses the magnets (24). Losses in the magnetic flux are thus reduced.

    摘要: The invention relates to an electric machine, particularly for a synchronous machine excited by a permanent magnet. The electric machine comprises a rotor arrangement (4) having buried permanent magnets (6) and a stator arrangement (2) having an inner recess (3) for rotationally movably receiving the rotor arrangement (4), the rotor arrangement (4) comprising a plurality of rotor segments (7), each having a pole shoe (10), the outer contour thereof corresponding to an arc contour having a contour radius, the contour radius being smaller than the radius of the rotor arrangement (4), thus forming a gap between two adjacent rotor segments (7), the at least one outer contour of one of the rotor segments (7) having an arc contour designed such that an air gap length ratio of the radial spacing between the inner recess (3) and the outer contour along a radial outer boundary of the corresponding rotor segment and the radial spacing between the inner recess and the outer contour along a radial center axis of the corresponding rotor segment (7) is optimized with regard to the distortion factor of the course of the flux density distribution of the pole shoe (10).

    摘要: The invention discloses an electrical machine, in particular a brushless synchronous motor that has a stator (14) and a rotor (12) with salient poles (18) disposed distributed over its circumference, each of which poles has an enclosed permanent magnet (11) and a pole shoe (19) that extends radially outward from the permanent magnet and defines an air gap (13) between the stator (14) and rotor (12). In order to achieve a low cogging torque and a low torque undulation, the pole shoes (19) are embodied as magnetically anisotropic, with a preferred direction of the greater magnetic conductivity extending parallel to the radial salient pole axis.
