Title: Apparatus for detecting rotational displacement angle
Inventor: KONDO TAKESHI
IPC: G01D5/48
Filed: 1990-09-28
Abstract: PURPOSE:To improve detecting accuracy by providing a plurality of magnetic bodies around the turning locus of a magnet, attenuating the magnetic elastic waves generated in the magnetic bodies with exciting means by the magnet which is fixed to the rotary shaft, and measuring a rotational displacement angle. CONSTITUTION:A permanent magnet 2 is fixed to the outer surface of a rotary shaft 1. Manetic bodies 4 and 5 are fixed to a supporting plate 3 so as to divide the turning locus of the magnet 2 into two parts. Exciting coils 6 and 7 and 8 and 9 are provided at both end parts of the magnetic bodies 4 and 5. The coils 6 and 7, and 8 and 9 generate magnetic elastic waves in opposite phases. Detecting coils 11 and 12 are further provided at the central points of the magnetic bodies 4 and 5 and detect the magnetic elastic waves which are propagated in the magnetic bodies 4 and 5 as the voltages. When the rotary shaft 1 is rotated, the magnetic elastic waves which are generated in the magnetic bodies 4 and 5 with the magnet 2 are attenuated. Thus, the amplitudes and the phases of the magnetic elastic waves detected with the coils 11 and 12 are changed in response to the position of the magnet 2. The rotational displacement angle of the rotary shaft 1 can be accurately detected based on the values.
