Abstract: A liner for use for a resilient stator of an electric machine for positioning between teeth formed in the stator. The stator is conformable from a first generally extending shape with opposed spaced apart ends and to a second generally hollow circular shape. The liner includes a central portion for positioning in a cavity between the adjacent teeth, a first end portion for limiting motion of the liner extending from the central portion and adapted to cooperate with a first end face of the stator, and a second end portion extending from the central portion and cooperating with a second end face of the stator, opposed to the first end face. The first end portion limits motion of the liner. The liner is positioned between adjacent teeth when the stator is in the first shape and remains in the cavity when the stator is in the second shape.
