Abstract

An angle sensor is disclosed. The angle sensor has a disc, a first magnetic pattern disposed on a side of the disc and including a number N1 of first portions of spirals regularly distributed in a first ring, and a second magnetic pattern disposed on a side of the disc and including a number N2 of second portions of spirals regularly distributed in a second ring. The numbers N1 and N2 are coprime and N1 is different from N2, N2−1, and N2+1.
