Abstract

A flexible shaft for torque transfer has a plurality of metal wires that are helically wound in a plurality of layers with an opposite winding direction that alternates from layer to layer. Each of the metal wires is surrounded by an electrically insulating insulation layer. The insulating layer prevents a metal-on-metal contact between adjacent metal wires and thereby prevents unwanted intermodulation products.
