1. An electric component for an electric machine, the electric component comprising:
a body having a slot defined therein;
a conductive winding extending out of a first axial end of the slot;
a first resin dam around the conductive winding at the first axial end of the slot, wherein the first resin dam blocks liquid communication through at least a space between the conductive winding and an inner surface of the slot at the first axial end of the slot, wherein the first resin dam includes a length of flexible material wrapped around the conductive winding extending out at the first axial end of the slot; and
an insulating resin in the slot and against the first resin dam at the first axial end of the slot.
