Abstract
A high frequency (HF) leakage current return wire-contained motor drive cable configured in a manner that one or multiple drive dielectric core wires and one or multiple HF leakage current return wires are arranged adjacent to and in close contact. Concurrently, the drive dielectric core wires and the HF leakage current return wires are arranged substantially parallel to the longitudinal direction and are stranded; and a sheath is provided without a shield being provided outside of the strand wires.
