摘要： A variable reluctance analog position device designed to determine the position variation of a target made from a ferromagnetic material. The device includes at least one magnet, the target and the magnet defining a gap therebetween. A magnetosensitive element detects induction variation produced in the gap by relative movement of the target relative to the magnet. The magnet is magnetized in a direction essentially perpendicular to the front surface of the magnet, which defines one edge of the gap. The magnet includes a cavity open at the front surface thereof and the magnetosensitive element is housed in the cavity. Moreover, the target is provided with a specific geometric configuration determined such that the induction variation according to the position of the target corresponds to a pre-defined function.

摘要： An electromagnetic actuator has four positions which are stable in the absence of a current and moves rapidly between these positions when acted upon by a current. The actuator has a thin, rotatable magnet (3) with two pairs of magnetic poles transversally magnetised in alternate directions, and a stator member having four pole pieces (9-12, 34-37, 48-51) of developed length P, each with an excitation coil. Two consecutive poles of the thin magnet (3) are spaced by a distance d. The thin magnet (3) is movable in an airgap of width E. wherein the size ratio P:E and P:d is greater than 8. The invention is useful for driving a device such as a valve or a switch.
