Abstract

The invention relates to a winding tooth (3) for a component (2) of an electrical machine (1), in particular for a stator and/or a rotor, comprising: a tooth shaft for being wound with a winding coil (4); and a tooth head (5) which is arranged at one end of the tooth shaft with respect to a winding axis; wherein one or more slots (14) are provided at at least one end section of the winding tooth (3), said slots extending along the winding axis through the tooth head (5), wherein the end section corresponds to a region at one or both ends of the winding tooth (3) along a transverse direction which runs substantially perpendicular to the winding axis.
