Abstract
The invention relates to an angular displacement sensor belonging to the field of rotary transformers. The angular displacement sensor inputs excitation by arranging an exciting winding to generate a changed magnetic field and the changed magnetic field is input to an input stator. The changed magnetic field is input to a magnetic core of a rotor by the input stator, and then, the rotation angle of the magnetic core of the rotor is output to an output stator armature by the magnetic field change of the magnetic core of the rotor to be transformed into electrical signals to be output, thus the measurement to the angular displacement of the magnetic core of the rotor can be realized. The angular displacement sensor can measure the rotation angle of +/-90 DEG of the magnetic core of the rotor by installing a magnetic circuit. The angular displacement sensor is novel in structure and convenient to process, and can not only realize functions of the angular displacement sensor, but also avoid disadvantages of the traditional structure, such as poor additional technology, low output precision, high installation difficulty, low product passing rate and the like.
