Inductive rotary encoder
By introducing a magnetic field sensor and processor into an inductive rotary encoder, the relative arrangement of the first and second components is measured using the magnetic field generated by the excitation coil. This solves the problem of difficulty in measuring the degrees of freedom outside the rotation axis in the prior art, and improves the measurement accuracy and signal strength.

AI Technical Summary
Existing inductive rotary encoders have difficulty effectively measuring the relative arrangement information of the first and second components in degrees of freedom other than around the axis of rotation.
By introducing a magnetic field sensor and processor into an inductive rotary encoder, the magnetic field generated by the excitation coil is used to measure the relative arrangement of the first and second components in degrees of freedom other than the rotation axis. Combined with a magnetic flux enhancer, the signal strength and system sensitivity are improved.
It enables precise relative arrangement measurement of the first and second components in degrees of freedom other than the axis of rotation, improving accuracy and sensitivity during installation and operation.
