摘要： A speed detecting device (1) includes a magnetic flux producing unit (2) for producing a magnetic flux changing at a predetermined frequency so that a magnetization pattern (7) is formed on a principal surface (6a) of a relative moving body (6) as the relative moving body (6) moves or rotates. This flux producing unit may be a rotor having permanent magnets, whose rotational speed is controlled, a coil which is excited at a controlled frequency, or a permanent magnet coupled to a voice coil which is excited at a controlled frequency.
A magnetic flux detecting unit (3) is arranged to detect an induced voltage, induced based on a magnetic flux produced by the magnetization pattern (7).
A magnetic flux frequency control unit (4) is arranged for controlling the predetermined frequency such that the induced voltage detected by the magnetic flux detecting unit (3) becomes zero, and a speed estimating unit (5) is arranged for estimating a moving or rotating speed of the relative moving body (6) in a state where the induced voltage detected by the magnetic flux detecting unit (3) is zero, based on the predetermined frequency controlled by the magnetic flux frequency control unit (4).
Alternatively, a rotor 8 having permanent magnets 8a may be driven by a magnetic flux produced by eddy currents generated in the moving body, to rotate passively at a speed with is lower than the speed of the moving body. This rotor speed will be measured. Additionally a voltage induced in a magnetic flux detecting unit 3 will be measured. With such an arrangement, it is possible to determine the speed of the moving body, based on a table or an arithmetic formula expressing a relationship between rotor speed, induced voltage and the speed of the moving body.

摘要： A speed detecting device (1) includes: a magnetic flux producing unit (2) configured to change, at a predetermined frequency, magnetic flux passing over the principal surface of the relative moving body; a stress detecting unit (3) for detecting a stress and outputting an electric signal corresponding to the stress; a stress transmitting member (4) for transmitting to the stress detecting unit (3) a Lorentz force produced in the magnetic flux producing unit (2) in accordance with magnetic flux produced by eddy currents occurring on the relative moving body (7) in accordance with a moving or rotating speed of the relative moving body (7); a frequency band extracting unit (5) for extracting a frequency component related to the Lorentz force from the electric signal; and a speed estimating unit (6) for estimating the moving or rotating speed of the relative moving body (7) based on the extracted frequency component.
The changing magnetic flux can be generated by a coil driven with an AC signal, or by a permanent magnet combined with a voice coil, and driven such that the gap between the magnet and the moving body changes at the predetermined frequency.
It is also possible to use a differential arrangement of two stress detecting units, one being responsive to both Lorentz forces and external disturbances, the other only to the external disturbances. In this case, also a unit producing a constant magnetic flux may be employed.
