Abstract (en)
[origin: DE19529528A1] In order to reduce the effect on a contactlessly transmitted signal from one component to another with an axial offset between a fixed and a movable vehicle component, there is a variable transformer, the pot cores of which for the primary (3, 11) and the secondary winding (4, 13) consist of either U (1, 2) or L-sections (10, 12). Said pot cores (1, 2, 10, 12) are arranged coaxially inside one another in such a way that one or more air gaps (8, 19, 20) between them run parallel to the axis of rotation (21) and are cut by the magnetic flux radially to the axis (9, 21). One of the surfaces of the two pot cores (1, 2, 10, 12) bordering the air gaps (8, 19, 20) is widened in relation to the other in the direction of the axis (9, 21).
