Abstract: The invention relates to a massage device with a variable shape for simulating the body and to a method for same, comprising a shaft-shaped core, a casing, within which the shaft-shaped core is at least partly arranged, and a chamber which is formed between the shaft-shaped core and the casing. According to the invention, the chamber is equipped with a plurality of filling bodies which provide the casing with a variable shape according to the arrangement of the filling bodies relative to one another and relative to the shaft-shaped core and the casing.

Abstract: A conductor bar for a stator winding of a rotating electrical machine includes a bundle of parallel conductor strands extending between two ends of the conductor bar and spaced apart by interspaces. A main insulation is wound around the bundle of conductor strands and a stack separators fills at least part of the interspaces. Protection elements are between the bundle of conductor strands and the main insulation. At least one of the protection elements or the stack separators are configured to compensate, at least in part, thermal expansion of the conductor elements when temperature changes.
