INDUCTION ROTATING TRANSFORMER Russian patent published in 2016 - IPC H01F38/14 

FIELD: electronic equipment.

SUBSTANCE: invention relates to electrical engineering, to transformers for contactless transmission of electric power on rotating device and can be used in instrumentation for improvement of devices for measuring angular displacements. Transformer comprises, installed with a common axis of rotation relative to each other with one degree of freedom, fixed (1) and mobile (2) flat plates of dielectric material, facing each other with sides having applied thereon identical flat printed inductance coils (3) and (4), respectively, in form of coaxially arranged broken concentric circles consisting of N turns. Adjacent along radius turns of concentric circles are connected to each other by straight inclined jumpers (5) and (6), respectively, located in broken interval at an angle close to 45° or 315° to radius. Straight inclined jumpers (5) and (6) of turns of concentric circles of coils (3) and (4), respectively, are made with width of jumpers, equal to width of turns of concentric circles. Induction rotating transformer may comprise X pairs of movable and fixed coils arranged on plates assembled in package, wherein except outermost, all plates of stack comprise double-sided printed coils.

EFFECT: technical result consists in improvement of stability of operation with constant transformation coefficient, which does not depend on turning angle and temperature conditions.
