摘要: A ring element includes a convex, in particular rounded, surface element for arrangement on at least one axial end region of a winding section of an electric motor rotor. The surface element provides a minimum radius curvature for supporting an inner layer of a rotor winding on the winding head. An insulating lamination element for an electric motor rotor onto which a rotor winding is intended to be wound includes the ring element. An electric motor, in particular a universal motor, includes a rotor with a rotor winding having the ring element. An electric machine tool, in particular a handheld electric machine tool such as an angle grinder, a drill, a saw or the like, includes the electric motor.
