Abstract
According to the invention, the position sensor is characterized in that the correction means (3) are achieved by at least one saturated magnetic pole, a so-called stabilization pole (Ps), having a sign opposite to the sign of the irregular pole (Pi) which is also saturated, each stabilization pole (Ps) extending from one to the other edge of the magnetic ring, by being inserted in the irregular pole, so as to stabilize the magnetic signal delivered by the passage of the poles adjacent to the irregular pole, said magnetic signal delivered between the passage of the adjacent poles not passing through the zero value.
