Patent number: 11268832Abstract: A coil assembly includes a coil winding and a multilayer printed circuit board. The coil winding has multiple loops that are arranged in different layers of the printed circuit board and form a main magnetic field with a main measuring direction perpendicular to a main plane of the printed circuit board. The loops arranged in different layers are electrically connected together via at least one via. The printed circuit board has at least four vias or a whole-number multiple of four vias that form an equal number of reverse current paths and forward current paths between the loops of the coil winding. Each pair of vias with the same current path direction is arranged point-symmetrically relative to a common mirror point such that magnetic loops that are formed on printed circuit board secondary planes arranged perpendicularly to the main plane have opposite directions and compensate for one another.Type: GrantFiled: June 12, 2017Date of Patent: March 8, 2022Assignee: Robert Bosch GmbHInventors: Thomas Buck, Andreas Merz, Oliver Krayl, Stefan Leidich

Patent number: 10458815Abstract: In one embodiment, a sensor arrangement for the contactless sensing of angles of rotation on a rotating part includes a disk-shaped target coupled to the rotating part. The disc-shaped target has at least one metal surface and generates at least one piece of information for ascertaining the instantaneous angle of rotation of the rotating part in connection with a coil arrangement. The coil arrangement has at least one flat detection coil. The arrangement further includes at least one measuring circuit that converts the inductance of a corresponding at least one flat detection coil into a measuring signal. The inductance changes due to eddy-current effects, as a function of the degree of overlap with the at least one metal surface of the rotating target. The arrangement further includes an evaluation and control unit that detects the measuring signal using measurement techniques and evaluates the signal for calculating the angle of rotation.Type: GrantFiled: October 1, 2015Date of Patent: October 29, 2019Assignee: Robert Bosch GmbHInventors: Stefan Leidich, Joerg Oberlaender, Oliver Krayl
