Abstract

In order to provide a transport system comprising a conductor system, which comprises at least one supply conductor, which is connected to an energy source, at least one transport carriage movable along a travel path relative to the conductor system and at least one means for the non-contact transmission of energy from the conductor system to the transport carriage, in which transport system the stationary conductor loop has an inductance that is as low as possible and in which ohmic losses are kept as low as possible, it is proposed that the transport system comprises at least one induction conductor, which at least in sections is arranged so closely adjacent to the supply conductor that an electric current flowing in the supply conductor generates an induction current in the induction conductor, wherein the induction conductor has at least two end regions, which are short-circuited to one another, and/or wherein the induction conductor is closed in a ring shape.
