  • 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.

  • Publication number: 20040084993
    Abstract: The invention relates to a method for installing a stator winding in a stator core (5), the stator winding being formed of at least one cable (1), which is flexible and comprises at least one electric conductor (50) with an envelope (51) capable to confine the electric field generated around the conductor. When a winding turn is to be formed, a cable portion is drawn out from the cable reel and inserted in its cross-direction into two winding slots. For the formation of each winding turn (10) that is jointlessly connected to first winding turn (10) that is jointlessly connected to a first winding turn (7) and has the same winding direction as the first winding turn, the cable portion forming this winding turn is made to include a cable section (13) corresponding to a cable turn on the cable reel that has been lifted off from the cable reel by way of a lateral movement over one (15a) of the gables of the cable reel.
