System for inductive transfer of power, communication and position sensing to a guideway-operated vehicle

摘要: Inductive transfer methods and structures combine, in a single system, at least two of the three functions transferring power, communicating data, sensing position with vehicle on guideway. A set conductors is installed guideway to inductively couple multiplicity diverse signals corresponding vehicle. The may be moving or stationary, coupled one both directions. Coupling effected without direct electrical contact, through common region gap, provide suitable precise air gap control for effecting coupling each signal. In addition, windings are arranged topology and/or symmetry cancel crosstalk between different signals.
