Inductive position sensor

An angular position sensor for determining an angular position of a conductive target, the position sensor comprising:

• at least one transmit coil;
• a first, second and third receive coil enclosed by the transmit coil, wherein each receive coil has a predefined electrical period which is the same for each receive coil and wherein each receive coil comprises a first conductive strand and a second conductive strand, wherein the complete first strand of a receive coil is obtained from a single conversion of a substantially sinusoidal primitive function to polar coordinates given the electrical period, and wherein the primitive function of the second strand is the primitive function of the first strand shifted over 180°, and wherein both strands are electrically connected so that a continuous coil is formed with two open ends, and wherein the primitive function of a strand of the second receive coil is the primitive function of a corresponding strand of the first receive coil shifted over 120°, and wherein the primitive function of a strand of the third receive coil is the primitive function of the corresponding strand of the first receive coil shifted over 240°;
• the conductive target with a surface parallel with a surface of the receive coils, and orthogonal to a rotation axis of the conductive target and wherein the surface of the conductive target overlaps with the surface of the receive coils and wherein the conductive target is a circular target with N protrusions, with N being a natural number;
• an integrated circuit which is configured for exciting the transmit coil, thus inducing signals on the receive coils, and for reading the signals from the receive coils or a combination of the signals, and for processing these signals, wherein the position sensor is configured for removing a common mode signal from these signals.
