Abstract:
In a method for producing conductor bars of a stator winding in an electric machine having a stator and a rotor rotatable therein, the improvement which comprises:forming each conductor bar by placing component conductors made of conductive material one above another in pairs, traversing a stack from a top layer obliquely to a bottom layer and each having uniform cranks in the vicinity of the top layer and in a bottom region;offsetting the cranks of each two component conductors placed one above another and assigned to one another in pairs in longitudinal direction at a spacing relative to the cranks of a succeeding or preceding pair of component conductors;placing the component conductors in two stacks located next to one another and laterally adjoining one another;placing each of the component conductors one above another in pairs and mutually interlocked by laterally neighboring component conductors, causing each conductor bar to extend partially on a surface of the stator facing toward and away from the rotor; andlocating the cranks of the component conductors of a pair of conductor bars at a spacing from one another in the longitudinal direction to produce an interspace relative to the component conductor of the pair of conductor bars disposed therebelow.
