Abstract

A sensor having multiple magnet blocks unevenly distributed in a housing, comprising, sequentially connected, a sensing element, a power-assist model processor (21), a digital-to-analog converter (27), and an operational amplifier (28). The sensing element comprises permanent magnet blocks (2) and a Hall element (3) arranged in a cavity fitted together by a rotating disk (1) and a fixed disk (40). Fixedly arranged on the rotating disk (1) are the multiple permanent magnet blocks (2) in a circular-annular distribution, while the spacing-intervals of the multiple permanent magnet blocks (2) are different. On a certain side of the rotating disk (1), the magnetic polarities of adjacent permanent magnet blocks (2) are opposite, that is, the magnetic polarities of all of the permanent magnet blocks (2) on the certain side of the rotating disk (1) are distributed in a pattern of N pole, S pole, N pole…; the Hall element (3) arranged on the fixed disk (40) is arranged at a position in proximity to the permanent magnet blocks (2). The N pole-S pole distribution of the magnetic polarities allows the Hall element (3) to acquire a rectangular wave signal, to add a digital processing for setting a power-assist model; the rectangular wave signal is allowed to express the positions of the permanent magnet blocks (2) on the rotating disk (1), and to determine the uses of different rectangular waves; the relative positions of the permanent magnet blocks (2) and of the Hall element (3) are fixed, and signal output is reliable.
