Abstract:
An angle sensor arrangement for measuring the rotational angle of a shaft (1) having a defined rotational angled measuring range, of more than 360° in particular, comprising a first gear wheel (2) and a first magnetic encoder (4) having at least one encoder lane, comprising one or more pole pairs, wherein said first gear wheel (2) and said first magnetic encoder (4) rotate with said shaft (1), and a second gear wheel (3) and a second magnetic encoder (5) having at least one encoder lane, comprising one or more pole pairs, wherein said second encoder (5) rotates with said second gear wheel (3) and said first and second gear wheels (2, 3) work together, and wherein said first encoder (4) and said second encoder (5) are each associated with at least one magnetic field sensor element (6, 7), wherein said first and said second gear wheels (2, 3) are implemented in regard to their shared transmission ratio and said first and second magnetic encoders (4, 5) are implemented in regard to their pole numbers so that the magnetic field sensor element (6, 7) associated with the first or the second encoder (4, 5) detects n poles or pole pairs in relation to the overall rotational angled measuring range of the angle sensor arrangement, and the magnetic field sensor element (7, 6) associated with the second or the first encoder (5, 4) detects n-l+Δ poles or pole pairs in relation to the overall rotational angle measuring range of the angle sensor arrangement, wherein Δ is defined as a real number between 0 and 1 and n is defined as a natural number.
