Abstract
The invention relates to a method for applying the main insulation of conductor bars, in particular conductor bars for stator windings, whereby the conductor bars have a rectangular cross-section. The method comprises the following steps: insertion of a conductor bar with ends in an injection mold; centering of the conductor bar in the injection mold so that a void for holding an insulation material remains between the conductor bar and the injection mold; filling of the void with an elastomer in order to form the main insulation.
