PHN 12.302 25.08.1988 ABSTRACT: " Rotating transformer." The transformer comprises a rotor core (1) in the form of a circular ferromagnetic disc which is rotatable about its axis (5), and a stator core (3) in the form of a circular, stationary ferromagnetic disc which is coaxial with the rotor core. The facing main surfaces of these discs are provided with grooves (11, 13) and ridges (15, 17) which are concentric with respect to the axis (5). In the grooves (11, 13) there are provided rotor windings (19) and stator windings (21), respectively. The stator windings (21) consist of conductor tracks on at least one main surface of a circular first portion (25) of a flexible, electrically insulating foil which is connected, via a strip-shaped intermediate portion (27) with connection conductor tracks (41), to a second circular foil portion (29) which supports further conductor tracks (37) and components (39) of an electronic circuit. The first foil portion (25) is secured on the main surface of the stator core (3) provided with grooves (13) and ridges (17) so that the ridges project through segment-shaped cut-outs (33) in the foil. The second foil portion (29) is secured on the other main surface of the stator core (3). Fig. 1.
