摘要： A multipolar resolver is so constructed that the need of the conventionally indispensable coil on the resolver rotor is eliminated by providing a center coil on a stator, and 5n or 3n rotor poles and 4n stator poles are provided where n is a positive integer. Sine and consine coils are wound on the stator poles alternately, thus simplifying the construction of the multipolar resolver.

摘要： There is disclosed a displacement transducer which comprises a plurality of planar circuit boards, each having a coaxial central aperture. Each of said boards having disposed thereon at least one spiral conductive structure which manifests a predetermined coil. The structure is oriented about the aperture and has a first and second terminal. The boards are positioned in a stacked array with each of said boards separated one from the other and with said central apertures aligned to form a central coaxial cavity. Leads are coupled to the first and second terminals of said boards for connecting certain ones in a primary winding configuration and others in at least two secondary configurations. A magnetic core adapted for insertion into said cavity varies the coupling between the primary and secondary windings according to the depth of insertion of said core within said cavity.

摘要： In a revolution counter using magnetic domain wall conductors which are wound each as a loop in a form of a spiral configured to be closed, in the connecting region the inner and outer loop section ends of the loop of a first magnetic domain wall conductor are combined and bridged by a second magnetic domain wall conductor which is connected to the magnetic domain wall conductor ends of the spiral with a respective gap therebetween, wherein the gap creates a local interruption of the domain wall conductor, and wherein the mean width of the gap is set to be smaller than the thickness of the domain wall conductors, and the adjoining domain conductor sections are encompassed by a non-magnetic layer in the gap region.

摘要： An inductive sensor includes a fixed part and a movable part. The movable part comprising a movable or deformable proof body, and a magnetic coupling element mechanically secured to the proof body. The fixed part comprising: a voltage generator and a coil transformer comprising an emission inductance mounted in parallel with the generator and a reception inductance. The magnetic coupling element being separated from an end of the emission inductance by a separation distance. The fixed part comprises an acquisition chain connected to the reception inductance and configured to generate a distance variation measurement signal. The measurement signal corresponding to a measurement of the variation of the frequency or of the amplitude of the voltage at the terminals of the reception inductance.

摘要： A processing device of a displacement detection device includes an AD conversion device, a switching circuit, and an arithmetic processing unit. The AD conversion device has first and second AD conversion units. The switching circuit periodically switches between a first connection mode in which a first differential signal is AD-converted by the first AD conversion unit and a second differential signal is AD-converted by the second AD conversion unit, and a second connection mode in which the first differential signal is AD-converted by the second AD conversion unit and the second differential signal is AD-converted by the first AD conversion unit. The arithmetic processing unit outputs displacement information of a scale based on an addition average value of the first differential signals output from the first and second AD conversion units and an addition average value of the second differential signals output from the first and second AD conversion units.

摘要： A sensor arrangement for redundant determination of an angle of rotation of a body about an axis of rotation includes at least one circuit carrier, a first sensor device having a first ECU and a second ECU. A magnet of the first sensor device and a coupling device of the second sensor device are each coupled in a rotationally fixed manner to the rotatable body. The first ECU is designed to receive signals caused by the rotational movement of the magnet and to generate at least one first electrical measurement signal which represents the current angle of rotation of the rotatable body. The second ECU is designed to receive signals caused by the rotary movement of the coupling device and to generate at least one redundant second electrical measurement signal which represents the current angle of rotation of the rotatable body.
