Abstract:
A rotary inductive electrical coupling comprising:(a) a first bobbin formed of non-magnetic material;(b) a first coil of electrically conductive material wound on said first bobbin;(c) a stator formed of magnetically permeable material dispersed in a non-magnetic medium molded over said first bobbin and first coil;(d) a second bobbin formed of non-magnetic material having a second coil of electrically conductive material wound thereon; and,(e) a rotor formed of magnetically permeable material dispersed in a non-magnetic medium molded over said second bobbin and second coil, wherein said rotor and stator have an annular configuration and are disposed in axially spaced side-by-side arrangement with respect to the axis of said first and second coil with the rotor rotatable with respect to the stator.
