<p>The invention relates to a machine component (20; 30; 40; 50; 60; 70; 90), in particular a rotor, for constructing an electrical machine, wherein the machine component (20; 30; 40; 50; 60; 70; 90) is substantially circular-cylindrical and has poles (22, 32; 46; 52; 62), at which a magnetic field occurs which is formed by at least one permanent magnet, wherein the poles (22, 32; 46; 52; 62) are each provided with a pole contour (23; 33; 45; 53; 63) which deviates from a purely circular-cylindrical lateral surface of the machine component (20; 30; 40; 50; 60; 70; 90), wherein the pole contours (23; 33; 45; 53; 63) of the poles (22, 32; 46; 52; 62) each have a plurality of sections in the axial direction over the length of the machine component (20; 30; 40; 50; 60; 70; 90), said sections being offset in the circumferential direction, wherein the at least one permanent magnet is substantially bar-shaped, in particular in the form of a right parallelepiped, and extends over at least one transition between two of the plurality of sections (A1, A2, A3).</p> |
