Patent ID: 7390972

Claim:
A winding for a linear motor, said winding comprising: three electrical cables arranged in grooves of an elongated inductor, wherein the three electrical cables each have an electrically conductive sheath and an electrically conductive intermediate layer arranged between the sheath and an outer conductive layer, and wherein at least one metal strand of an electrically highly conductive material that has electrically highly conductive contact with the conductive sheath of the cables and serves as a grounding conductor is present over the whole length of a stator, which comprises the inductor and the three cables, which are connected to form a three-phase winding, wherein the intermediate layer is formed from nonwoven material that has a thickness of about 300 μm-600 μm and an electrical resistance of about 150 Ω/m-500 Ω/m; and wherein the value of the electrical resistance of the intermediate layer is greater than the corresponding resistance value of the strand used as the grounding conductor.
