Rotation detection assembly, electronic equipment and detection method

The invention discloses a rotation detection assembly, electronic equipment and a detection method, and belongs to the technical field of electronics. The rotation detection assembly comprises a first part and a second part which can rotate relatively; one end, close to the second part, of the first part is provided with an eddy current induction piece, and one end, close to the first part, of the second part is provided with a first coil and a second coil which are used for loading alternating current; the orthographic projection of the first coil on the plane perpendicular to the axial direction and the orthographic projection of the eddy current induction piece on the plane perpendicular to the axial direction have a first overlapping area. The orthographic projection of the second coil on the plane perpendicular to the axial direction and the orthographic projection of the eddy current induction piece on the plane perpendicular to the axial direction have a second overlapping area, and in the process that
