ABSTRACT:
A system for coupling electrical power to a rotary shaft without mechanically contacting the shaft includes a stationary transformer primary core positioned adjacent but spaced from the shaft so that the shaft forms part of a complete magnetic flex path for the core, and an insulated conductor mounted directly upon the shaft in the form of a winding which is positioned to be inductively associated with the transformer primary.
