Abstract
A pole shoe of an electric machine limits a winding surface of a rotor that can rotate about an axis of rotation. The pole shoe is connected to a pole web of the rotor. An outer side of the pole shoe, which faces away from the pole web in the connected state, has a first region having a substantially sinusoidal contour profile and a second region having a second contour profile. The second contour profile is different from the first contour profile and is formed in such a way that the winding surface in a circumferential direction of the rotor is lengthened with respect to a winding surface of a pole shoe having an outer side extending exclusively substantially sinusoidally.
