Abstract:
An elastic insulating material element for wedging a winding of an electric machine in slots provided in a laminated body,wherein the insulating material element comprises a striplike metal spring core which is embedded within a casing made of an insulating material,wherein the insulating material completely surrounds the metal spring core and adheres to the metal spring core, and the insulating material and the metal spring core form an integral unit,wherein the insulating material element is nonmagnetic, andwherein the metal spring core comprises means for limiting eddy currents induced in the metal spring core, the means for limiting induced eddy currents comprising slitlike incisions which, arranged so as to be distributed in the longitudinal direction of the metal spring core, project into the interior of said metal spring core, in each case starting from longitudinal edges of the metal spring core.
