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...

Problems solved by technology

This method is relatively convenient to calculate and can obtain high static angle measurement accuracy, but it needs to artificially reverse the tooth disc by 17 teeth, and it is also impossible to obtain continuous position and dynamic angle measurement accuracy
