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.

A handheld power tool has a housing having two separate housing parts, between which a primary damping element is disposed, wherein a secondary damping element is disposed acting parallel to said primary damping element. During regular function of the primary damping element, the secondary damping element is at least approximately force-free. In the event of a changed relative position between the two housing parts, the damping occurs via the secondary damping element.
