1. A method for creating spacing between insulated stator coils comprising:

  • positioning an expandable container between stator coil end portions;

    inflating the expandable container between the stator coil end portions thereby creating a first space between the stator coil end portions;

    placing a first insulating element in the first space between the stator coil end portions at a first location, wherein the first insulating element is permanently placed between the stator coil end portions;

    deflating the expandable container either completely or only partially;

    after deflating the expandable container, shifting the expandable container along the stator coil end portions outward and away from a stator of an induction machine;

    inflating the expandable container again; and

    placing a second insulating element in a second space between the stator coil end portions at a second location, wherein the second space is different from the first space and wherein the second insulating element is permanently placed between the stator coil end portions.
