摘要： A linear oscillating motor capable of assuring a consistent and effective feedback control of keeping a constant oscillation amplitude with varying load conditions. The linear oscillating motor comprises an oscillator carrying a permanent magnet, and a stator with an electromagnet. The electromagnet is supplied with an electric power to develop an electromagnetic drive force of moving the oscillator in a linear direction relative to the stator. A spring is provided to apply a restoring force to the oscillator for providing a linear oscillating motion to the oscillator. A photo-sensor monitors the linear motion of the oscillator and outputs a signal to a reverse-point detector which determines right and left reverse points of the oscillator. A controller applies the electric power to the electromagnet at the drive points respectively defined subsequent in time to the reverse points and in a varying amount for keeping a constant oscillation amplitude of the oscillator. The photo-sensor outputs a train of pulses appearing each time the oscillator passes its oscillation center. The reverse-point detector determines the reverse points based upon a time period between the two preceding pulses. Since the photo-sensor can monitor an oscillation cycle of the oscillator without being affected by the magnetic field developed by the electromagnet for driving the oscillator, it provides a reliable basis for accurately determining the reverse points and therefore the drive points. Accordingly, the driving force can be applied at an optimum timing to make the feedback control accurately and reliably.

摘要： This invention relates to a position sensor featuring a stator (1) defining an air gap inside of which a mobile magnet (3) integral with a coupling shaft (4) moves. The sensor features a Hall probe (12) for measuring the variation of the induction in an air gap (10). The stator (1) is formed of a first stationary part and a second part (2) which is either stationary or mobile, the two parts defining between them a main air gap (5) in which the part of the mobile element moves. The mobile element exhibits at least two adjacent thin parts magnetized crosswise in alternate direction, the magnetized parts being made of a material exhibiting in the entire working area a practically linear demagnetization characteristic and a reversible permeability close to that of the air. The stationary part exhibits at least two secondary air gaps (10, 11) approximately perpendicular to the main air gap (5) in which the mobile element moves. The Hall probe (12) is housed in one of the secondary air gaps (10, 11). The L/E ratio is greater than 6, L designating the width of a magnetic pole and E designating the width of main air gap (5).
