Magnet rotation angle sensor

摘要

An adjustable unit (11) is provided, connected with the Hall sensors (1,2), and is controlled by adjusting values (P). In which at least one of the measurement signals (x,y) is multiplied with function valves (w) of a function (f). The function (f) is so selected, that for each angle of rotation(alpha) of a sector, an unambiguous adjusting value (P) is given. With which the output signals of the adjusting unit (11) are of equal size. A comparator (6) is provided, to which at least one output signal of the adjusting unit is supplied, for comparison with a reference signal. A control unit (8) alters the adjusting value (P), until the adjusting value (P) allocated to the angle of rotation (alpha) is found.
