Abstract

The invention provides a back-to-back induction synchronizer. An upper induction synchronizer is fixedly connected with the upper end of a common rotating shaft system; an upper stator tray is fixed at the upper end of the upper induction synchronizer; a rotating shaft sleeve is fixed at the lower part of the common rotating shaft system; a lower stator tray is arranged at the upper end of the rotating shaft sleeve; a lower induction synchronizer is arranged at the upper end of the lower stator tray; and an upper rotor tray and a lower rotor tray are fixed at the middle part of the common rotating shaft system, and are parallel to the upper stator tray and the lower stator tray. The back-to-back induction synchronizer adopts an operating principle that after an observation set begins, the upper induction synchronizer and the lower induction synchronizer can rotate together with a shaft, corresponding angular position signals are output in real time by an angle measurement circuit in n measurement positions, and readings of the master induction synchronizer and the slave induction synchronizer are directly read out from an angle display device, and are subtracted for separating error data of the upper induction synchronizer and the lower induction synchronizer by a combination intercomparison method.

Description

technical field [0001] The invention relates to a back-to-back induction synchronizer, belonging to the technical field of induction synchronizers. Background technique [0002] The induction synchronizer is a device that converts linear displacement or angular displacement into electrical signals by using electromagnetic principles. Position measurement using inductosynchronizers is not perfect, such as dimensional deviations caused by insufficient manufacturing accuracy, conditional errors caused by installation and adjustment, and inherent distortion of inductosynchronizer components due to the presence of harmonic magnetic fields and harmonic potentials. Principle errors and so on. As a result of the above phenomena, errors will be introduced into the position measurement of the inductosynchronizer. Inductosynchronizers account for a large proportion of the angular position measurement market, and high precision is a major advantage of them compared to other goniometri...
