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.

Abstract
Methods and system for creating spacing between insulated stator coils include a spacing device with an expandable container. The expandable container is positioned and expanded between stator coil end portions in order to create a space between the insulated stator coil end portions. Insulating elements are placed in the space created between the stator coil end portions, and the expandable container removed.
