Abstract

The invention provides a dynamic measurement angle calibration device and a calibration method of a round inductosyn. The calibration device is installed on an operation platform (1) and comprises a base(2), an axis system (3), a permanent magnet synchronous torque motor (4), the round inductosyn, a circular grating, a reading head (6), a metal regular icosahedron prism (7), an optoelectronic autocollimation instrument (8) and two orthogonal gradienters (9). The calibration method mainly includes a calibration preparation step, an axis system dip angle rotation error detection step, a circularinductosyn and circular grating static-calibration step, a circular inductosyn and circular grating reference zero position measurement step, a dynamic measurement angle calibration and compensationstep and a repeated calibration verification step. The dynamic measurement angle calibration device has the advantages of high calibration accuracy and convenient device adjustment and meanwhile integrates the advantages of static and dynamic measurement angle precision calibration, and the high-precision dynamic continuous calibration of circular inductosyn measurement angle precision is really achieved.

Description

technical field [0001] The present invention relates to the technical field of angle dynamic precision measurement and calibration, in particular to a dynamic angle measurement precision calibration device and a calibration method for a circular induction synchronizer, in particular to a dynamic angle measurement precision calibration method for a high-precision circular induction synchronizer. Background technique [0002] The circular induction synchronizer is a new type of high-precision angle detection element and angle feedback element. It is a multi-pole pair planar printed winding component that works on the principle of electromagnetic coupling. It consists of a stator and a rotor. When the stator winding is excited by high-frequency current, an induced potential is generated in the rotor winding. The change value of the rotor electric signal directly reflects the change amount of the mechanical angular displacement, and after circuit processing, high-precision angle...
