Abstract (en)
[origin: WO2018172178A1] The invention relates to a pole shoe (2), to an electric motor having such a pole shoe (2), and to a vehicle. The pole shoe (2) for limiting a winding surface (10) of a rotor that can rotate about an axis of rotation, in particular of an electric motor, is connected to a pole web (4) of the rotor. An outer side of the pole (2), which faces away from the pole web (4) 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 (10) in a circumferential direction of the rotor is lengthened with respect to a winding surface (10) of a pole shoe (2) having an outer side extending exclusively substantially sinusoidally.
