Device useful for signal transfer from static surface to rotating surface and viceversa

摘要

A device useful for transferring signals from static surface to a rotating surface, said device comprising a pair of pot cores acting as a primary and secondary core and said primary pot core being wound with 'N1' number of turns and said secondary pot core being wound with 'N2' number of turns of a conducting wire respectively, such that each turn of the wire rests on top of the previous turns thereby increasing inner diameter of the pot core by a wire thickness each time, one of the said pot core is mounted on a rotating surface and the other pot core being fixed to a static surface with minimum air gap between each other such that the coils are always facing each other even if the primary and the secondary cores are rotated through 0 to 360° with respect to each other.
