    摘要: a high-voltage generator, notches (3) leading radially inward are provided in each segmental lamination (1) on the radial outside of the laminated stator body and end in a relief opening. The notches (3) cause the amplitude and the frequency of, for example, a 4-node vibration occuring during operation to be limited to noncritical values, although the laminated body is undersized mechanically with regard to its yoke height (JH).

    摘要: 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.
