Inductive angular-position sensor, including a partially metallized disk that moves in rotation around its axis of revolution; and a stator that includes a primary coil and several secondary coils, whereby the secondary coils are arranged essentially symmetrically in pairs relative to the axis of revolution, so as to form one or more pairs of secondary coils, whereby the secondary coils of each pair are connected, on the one hand, to one another, in series and in phase opposition relative to one...

A low cost, low profile, small size and high performance inductive device for use in, e.g., electronic circuits. In one exemplary embodiment, the device includes a ferrite core comprising multiple inductors and optimized for electrical and magnetic performance. Improvements in performance are obtained by, inter alia, control of the properties of the gap region(s) as well as placement of the windings relative to the gap. The magnetic path properties of the inductors at the ends of the device are ...

According to one embodiment, there is provided an inductive multi-turn encoder which employs inductive means to determine the number of revolutions a central shaft operably connected to the module has turned. The inductive coils comprise emitter coils and receiver coils, which are operably associated with and opposed to corresponding geared circular disks, which in turn are arranged to implement a predetermined gear reduction ratio. The inductive multi-turn encoder is capable of operating under ...

An inductive proximity sensor includes a coil or inductance arranged in the vicinity of an active surface or end of the sensor, a current source repeatedly supplying the inductance, and a signals processor for signals corresponding to the voltages induced in the coil when fed. The induced voltages are influenced by the presence of objects within a given detection area, depending on their distance and on their constituting material. The coil or inductance is part of a parallel LC circuit. The cur...

An inductive power transfer system including a synchronous drive system having a resonance control module. The resonance control module includes a primary coil module with a primary LC circuit. The resonance control module seeks and detects the resonant frequency of the primary LC circuit. The synchronous drive system further includes a switching coil amplifier for selectively energizing the primary coil to keep the primary LC circuit operating at or as close as possible to its natural resonant ...

Apparatus and associated systems and methods may relate to a process for supplying unidirectional current to a load, controlling a reverse electromotive force (REMF), capturing inductive energy from the load, and supplying the captured inductive energy to the load. In an illustrative example, an operating cycle may include a sequence of operations. First, inductive energy captured from the load on a previous cycle may be supplied to the load. Second, energy may be supplied to the load from an ex...
