Abstract
An inductive power transfer system for the shaft mounted electronics of a rotary torque signal generating system includes a pair of planar PCB inductors formed by spiral copper traces on the planar surfaces of one or more layers of PCB substrate material. A primary inductor comprising a copper trace on a planar PCB substrate surrounds but is not connected to a steel torque transmission shaft. A secondary PCB trace inductor on another planar substrate is mounted for rotation with the shaft and in coaxial relation with both the shaft and primary inductor substrate so as to be inductively linked therewith.
