  • Method for installing a stator winding
    Patent number: 7152306
    Abstract: A method for installing a stator winding in a stator core. A winding turn is formed by drawing a cable portion from a cable reel and inserting it into two winding slots. Each winding turn that is jointlessly connected to first winding turn and has the same winding direction as the first turn is formed by making this winding turn include a cable section corresponding to a turn on the reel that has been lifted off the reel by lateral movement over a gable of the reel. To form each winding turn that is jointlessly connected to the first winding turn and has a second winding direction opposite the winding direction of the first turn, the cable portion forming this winding turn is made to include a section corresponding to a turn on the reel that has been lifted off the reel by lateral movement over the other gable.
