摘要： In a linear position encoder, a support is provided upon which a pair of phase quadrature windings are mounted. The windings are arranged to have a sinusoidal magnetic sensitivity characteristic along the length of the support. Mounted on a movable element there is a resonant circuit including a coil and capacitor that can magnetically couple with the windings. When the circuit is excited, it induces currents in the windings that are dependent upon the position of the circuit within a period Ts of the windings. An excitation and processing unit is provided to energize the circuit and to process the signals induced in the windings. The excitation and processing unit is operably coupled to an external high permeability rod extending along the measurement path in a first plane having the windings but removed therefrom. The rod has first and second excitation coils connected in series and wound around the rod and disposed at opposite ends defining a length of the rod.

摘要： A position detector is provided for detecting the relative movement of first and second members which are mounted for relative movement along a measuring path. One of the members comprises a magnetic field generator for generating a magnetic field and the other member comprises first and second conductors which are inductively coupled to said magnetic field generator. The arrangement of the first and second conductors and the magnetic field generator is such that output signals are generated in a first and second receive circuits whose position varies with the relative movement between the two members. In addition to carrying information relating to the relative position between the two members, the signals induced in the receive circuits also comprise information defining the relative orientation of the two movable members, and by suitable processing of the received signals the relative orientation of the two members can also be determined. In a preferred form of the invention, the system operates to define the relative position and orientation of the two movable members in first and second directions from which the relative orientation of the two members in a plane containing the two directions can be determined. The signals induced in the receive circuits can also be processed to give an indication of the gap between the two circuits and to provide an indication of the full relative orientation of the two members.

摘要： A dual phase resolver to digital converter having two separate channels for generating rotor position data. The first channel generates an indication of rotor position based on a sinewave type reference signal applied to a first stator winding and the rotor signal while the second channel provides an indication of rotor position based on a cosinewave type reference signal applied to the second stator winding and the rotor signal. Logic circuitry associated with the data channels provide separate fault data indicative of when position data may be subject to error. The data from the two channels are selectively combined in the output of the converter. Data from one channel is used when the other channel is subject to fault. An average of the data is used when both channels are operating properly in order to provide greater accuracy.

摘要： An electromechanical positioner indicator is provided which comprises first and second relatively movable parts, the first part including two oppositely facing surfaces which are everywhere equidistant and the second part including two surfaces which are everywhere equidistant and which are everywhere equispaced from and lie, closely adjacent to respective ones of the two surfaces of the first part. A first coil, preferably in printed circuit form, is secured to the first part and sensing coils, also preferably in printed circuit form, are secured to each of the two surfaces of the second part. The inductive coupling between the coils is dependent on the relative positions of the parts and thus the output of the sensing coils provides an indication of position. In one embodiment, the surfaces in question are formed by cylinders and in another, the first part is a disc and the main coil comprises an annulus. Particular coil and coil conductor shapes are also disclosed.

摘要： A harness for an electromagnetic transducer such as an INDUCTOSYN-type slider includes four separate series of thin flat U-shaped connectors stacked on top of each other for connecting the ends of the U-shaped conductors on the slider to each other in the desired pattern. Each separate series of connectors are separated from each other by a thin film of insulating material, with the ends of each connector projecting beyond one edge of the insulating film to form tabs which are aligned with the ends of preselected U-shaped conductors for connection thereto. The end tabs of the connectors may be joined to the conductors by a single soldering operation, and the entire harness assembly may be prefabricated by laminating the four series of connectors to each other. The connectors are formed by printed circuit techniques.

摘要： A magnetic resolver that includes: an annular stator portion having a protruding core; an annular coil substrate on which a coil portion, which is disposed around the protruding core, is formed as a patterned thin-film coil; and a rotor portion disposed to face the stator portion from above, with the coil substrate interposed therebetween, wherein the amount of overlap between a top face of the protruding core and the rotor portion, when viewed from above, varies as a rotation angle of the rotor portion relative to the stator portion varies. The annular coil substrate may be constituted of substrate pieces that have shapes obtained by dividing the annular shape, which facilitates increasing the yield rate in the number of substrate pieces that can be produced from a substrate material.

摘要： There is described an inductive sensor for sensing a parameter such as position. The inductive sensor comprises: receive aerial which is electro-magnetically coupled to a magnetic field generator via a resonant circuit with the electromagnetic coupling varying in dependence upon the sensed parameter so that a sense signal induced in the receive aerial is representative of the sensed parameter. The magnetic field generator generates a magnetic field comprising a first magnetic field component at a first frequency which is operable to induce resonance in the resonant circuit and a second magnetic field component at a second frequency which is not operable to induce resonance in the resonant circuit. The signal processor processes the sense signal to generate a signal component corresponding to a first component of the sense signal at said first frequency adjusted using a second component of the sense signal at the second frequency so that a noise component of the first component of the sense signal is reduced, and determines a value representative of the sensed parameter using the signal component.
