Abstract
An apparatus for supporting conductor bars of an end winding of a stator winding of an electric machine having a lamination stack includes pressure plates holding the lamination stack together, support angles supporting the conductor bars in the vicinity of the end winding, a support ring being directly axially adjacent the pressure plate and having an inner periphery, the support angles having radially outer surfaces braced against the support ring, the support angles being guided and partially disposed in radially extending slots formed in the pressure plates, and spacers in the shape of ring segments resting on the inner periphery of the support ring and preventing tangential deflection of the support angles.
