Sensing element with unevenly distributed multiple magnetic sheet locations and magnetic flux inside casing
InactiveCN103383270AUnlimited quantitySimple structureConverting sensor output electrically/magneticallyRider propulsionControl signalMagnetic polarity
The invention discloses a sensing element with non-uniform distribution of multiple magnetic block positions and magnetic flux in a casing and belongs to a technology of providing a control signal by multi-point magnetic induction. Permanent magnet blocks and a Hall are arranged in an inner hollow casing formed by embedding a rotary disk with a fixed disk; a plurality of permanent magnet blocks which are circularly distributed are fixedly arranged on the rotary disk; the permanent magnet blocks are different in space and magnetic flux; magnetic polarities of adjacent permanent magnets on a certain surface of the rotary disk are opposite, i.e., the magnet polarity distribution mode of all permanent magnet blocks on the certain surface is N pole, S pole, N pole and the like; and the Hall on the fixed disk is arranged at a position close to the permanent magnet block. The sensing element has the advantages that the magnetic polarities of adjacent permanent magnets are in an NS opposite distribution mode, so that the Hall can acquire a rectangular wave signal which is conveniently and digitally processed; by using the characteristics that the spaces and the magnetic fluxes are respectively different, the rectangular wave signal can express the position of the permanent magnet blocks on the rotary disk and determine purposes of different rectangular waves; and a relative position between the permanent magnet blocks and the Hall is fixed, and thus the reliability in signal output is realized.
