Abstract: A stator for an axial flux machine including a disc-shaped multilayer printed circuit board with a plurality of layers stacked one over the other. Each layer includes an electrically insulating substrate and at least one first conductor path which is applied onto the substrate and/or is introduced into the substrate. The at least one first conductor path forms a first winding, and a second conductor path forms second a winding. The layers can be electrically contacted with each other by means of vias running perpendicularly to a disc-shaped plane, wherein conductor paths connected together via the layers form a stator winding, and each pair of adjacent windings in a circumferential direction are connected together in a common layer. A first via is provided for a first winding end of the first winding, and a second via is provided for a second winding end of the second winding.

Abstract: The invention relates to a roller bearing (01), with a revolving bearing component (05) and a stationary bearing component (04), and with a capacitive sensor unit (02). The capacitive sensor unit (04) comprises a pivoted sensor element (08), which is connected to the revolving bearing component (05), and a stationary sensor element (09). The sensor units (08, 09) form a capacitor. At least one of the sensor elements (08, 09) bears a first material measure (14, 16), so that a change arises in the capacitance of the capacitor when there is a relative motion in the sensor areas (08, 09). The sensor unit also includes a means for generating a periodic electrostatic field between the sensor plates, and a processing and amplifying electronics unit for evaluating the change in capacitance.
