Title: Rotation speed detecting device
Inventor: FUKUSONO HIDEKI
IPC: G01P3/488
Filed: 1994-09-14
Abstract: PURPOSE: To provide a rotation speed detecting device capable of detecting not only the speed but also the direction of rotation. CONSTITUTION: A plurality of sawtoothed portions 1a are provided in such a way as to project from the outer peripheral surface of the periphery of a rotor 1. A detecting coil 3 producing a high-frequency magnetic field is placed close to the rotor 1. A magnetic field is produced by an eddy current occurring in the rotor 1, varying the oscillation amplitude of the detecting coil 3. A gap between the rotor 1 and the detecting oil 3 varies as the rotor 1 rotates, because of the toothed portions 1a. Since the portions 1a are sawtoothed, an output taken out of a detecting portion 2 and being proportional to the toothed portions 1a changes its way of varying according to the direction of rotation of the rotor 1.  This output is differentiated by a differentiating circuit 8 and thereby a differential signal corresponding to the direction of rotation of the rotor 1 is obtained and compared with a reference value at a direction discriminating circuit 9 consisting of a comparator, and a binary signal corresponding to the direction of rotation of the rotor 1 is obtained so that the direction of rotation can be determined.
