Title: Rotation detector
Inventor: ARAKAWA MIYAO
IPC: G01D5/244
Filed: 1980-06-09
Abstract: PURPOSE:To easily obrain many pieces of rotating information by a continuous part and a discontinuous part from one magnet and increase strength by providing the discontinuous material part in a rotary magnet for detecting rotation. CONSTITUTION:A rotary magnet 1 of a cylindrical shape is alternately magnetized in a circumferential direction, and includes a discontinuous material part 1-1. The discontinuous part is constituted of a material (for example, rare earth cobalt) which is magnetized stronger than other parts of the magnet 1 or the density of ferrite is made higher. A magnetism converter 2 is so disposed as to detect the magnetic flux of the rotary magnet, and 2-1 detects the magnetic flux on the circumferential surface including the discontinuous part and 2-2 detects the magnetic flux on the circumference of only the continuous part. In this way, many pieces of rotation information are easily obtained from one magnet, and since there are no shape defects, the strength is high; in addition, the magnet is magnetized after molding and therefore, its accuracy is good.

Abstract: PURPOSE:To reproduce a speed signal which approximates an actual speed and on which the influence of a mechanical resonance point is little, by allowing a signal obtained by differentiating the position signal of a magnetic head to pass a notch filter or the like and synthesizing this signal with the current of a voice coil motor. CONSTITUTION:The signal obtained by differentiating the position signal of the magnetic head is allowed to pass the notch filter or a low-pass filter and is synthesized with the current signal flowing to the voice coil motor by an electronic tachometer to reproduce the speed signal of the magnetic head. The influence of oscillation of the mechanical resonance point is reduced because the signal obtained by differentiating the position signal of the magnetic head is allowed to pass the notch filter or the low-pass filter, and the speed signal is reproduced with the current flowing to the voice coil motor by the electronic tachometer to interpolate the band where the phase is delayed by gain reduction due to the notch filter or the low-pass filter.
