Round inductosyn capable of eliminating mounting error

Abstract

The invention relates to a round inductosyn capable of eliminating mounting error. The round inductosyn capable of eliminating mounting error is characterized in that a round surface of a rotor or a stator of the round inductosyn is divided into an inner ring (1) and an outer ring (2) along the radial direction; the inner ring (1) is positioned in the middle and is a round area, and the outer ring(2) is positioned at the periphery and is an annular area; the inner ring (1) and the outer ring (2) are concentric; the inner ring (1) and the outer ring (2) are wound an inner ring winding (3) andan outer ring winding (4) correspondingly; the inner ring winding (3) and the outer ring winding (4) are staggered by one polar distance, namely an electric angle pi, along the circumference; the inner ring winding (3) and the outer ring winding (4) have the same width along the radial direction; the radial spacing between the inner ring winding (3) and the outer ring winding (4) is 1 to 2 mm; inaddition, two points, between which the distance is 180 degrees, on the edge of the outer circumference of the outer ring (2) serve as incremental encoding starting points of inner ring winding (3) and the outer ring winding (4) correspondingly, namely a starting point I (5) and a starting point II (6).

Description

technical field [0001] The invention relates to the technical field of circular induction synchronizers, in particular to a circular induction synchronizer capable of eliminating installation errors. Background technique [0002] The circular induction synchronizer is an angular position detection element that works on the principle of electromagnetic induction. It consists of a stator and a rotor. Continuous radial distribution windings are printed on the rotor, and the number of lines of the radial windings is the number of poles of the circular induction synchronizer; orthogonal sinusoidal and cosine distribution radial segmental windings are printed on the stator. When the stator and rotor are assembled, there is a certain air gap between them. When one winding is excited by high-frequency current, the other winding will generate induced potential, and the induced potential will be generated with the relative rotation of the stator and rotor. regular changes. The induc...

AI Technical Summary

Problems solved by technology

Usually, the coaxiality of the stator and rotor relative to the rotating shaft is required to be within 0.01mm, the verticality is required to be within 0.02mm, and the air gap between the stator and rotor must be controlled within the range of 0.2±0.05mm. If the installation requirements are not up to standard, there is eccentricity Or tilt will cause a significant increase in angle measurement error
