摘要： A displacement sensor includes an induction element and sensor element. The induction element has an electrically conductive measurement track element extending along a measurement path, and two electrically conductive correction track element positioned adjacent to each other relative to the path. The sensor element is movable relative to the induction element along the measurement track element, and has a measurement coil positioned over the measurement track element and two correction coils positioned adjacent to each other relative to the path. A position change of the measurement coil on the path changes an overlap of the measurement coil and the measurement track element along the path such that an induction of the measurement coil is configured with reference to the position of the measurement coil on the measurement path. Each correction coil is positioned over a respective corrective track element such that an overlap of the correction coil over the respective corrective track element is constant.

摘要： A rotation angle sensor includes a stator element and a rotor element, which is mounted in a rotatable manner about an axis of rotation with respect to the stator element. A rotation angle is captured via inductive coupling between the rotor element and the stator element. A compensation element is arranged on the stator element. The compensation element has a compensation transmitting coil configured to emit an alternating electromagnetic compensation field and at least one compensation receiving coil configured to receive alternating electromagnetic fields. The rotor element has a first electrically conductive section. The first electrically conductive section is arranged on the rotor element and is inductively coupled to the compensation transmitting coil and to the at least one compensation receiving coil of the compensation element.

摘要： A brushless DC motor configured with an external rotor includes an analysis and control unit, a stator, a rotor, a co-rotating bell, and a sensor that detects an angular position of the rotor. A target with at least one electrically conductive track is attached to the co-rotating bell, and the sensor is configured as an eddy current sensor with at least one coil. The sensor is arranged at a radial distance from the target such that the at least one electrically conductive track at least partly covers the at least one coil. The sensor provides an angle signal as a function of the at least one coil being covered by the at least one electrically conductive track. The angle signal uniquely represents the absolute angular position of the rotor up to 360°. A method includes providing an angle signal for the brushless DC motor.

摘要： A linear travel measurement apparatus is configured for a compression travel of an electrically conductive spring. A spring unit includes the linear travel measurement apparatus and a spring. The spring has an electrical contact at each of its ends and is electrically connected to a measurement circuit by corresponding electrical lines as measurement inductance. The measurement circuit detects a change in the measurement inductance, the change caused by the compression travel, and evaluates said change in order to ascertain the spring travel.

摘要： The present disclosure relates to a thermal sensor and a method for producing a thermal sensor of this type having a low signal-to-noise ratio at relatively high signal strengths. To this end, a thermoelectric generator is combined with a field effect transistor and a diode. Owing to its integrated diode and the barrier effect associated therewith, the thermal sensor is suitable for the economical and efficient design of imaging sensor arrays for converting thermal radiation into electrical signals.

摘要： A rotational angle sensor includes a stator element and rotor element. The stator element has a stator transmitting coil and stator receiving coil. The rotor element is rotatably mounted about a rotation axis, relative to the stator element, and has a rotor receiving coil and rotor transmitting coil electrically connected to each other. The rotor receiving coil is inductively coupled to the stator transmitting coil such that an electromagnetic field produced by the stator transmitting coil induces a current in the rotor receiving coil that flows through the rotor transmitting coil and causes the rotor transmitting coil to produce a further electromagnetic field. The stator receiving coil is inductively coupled to the rotor transmitting coil such that the inductive coupling between the stator receiving coil and the rotor transmitting coil is configured with reference to a rotational angle between the stator element and the rotor element, and such that the further electromagnetic field induces an angle-dependent alternating voltage in the stator receiving coil. The stator transmitting coil has a first circular outer partial winding, and a first circular inner partial winding positioned within and electrically connected to the first outer partial winding such that the first inner partial winding has an opposite current flow with respect to the first outer partial winding. The rotor receiving coil has a second circular outer partial winding and a second circular inner partial winding positioned within and electrically connected to the second outer winding such that the second inner winding has an opposite current flow with respect to the second outer partial winding. The first and second outer partial windings, and the first and second inner partial windings are oriented with respect to each other, respectively.
