Abstract
A linear electromagnetic actuator includes a stator excited by at least one electric coil arranged around an axis of symmetry and two ferromagnetic stator poles positioned axially on either side of the coil, as well as at least two independent moving members, each of the moving members being formed of a ferromagnetic material, where the linear electromagnetic actuator includes at least three magnetized poles arranged inside the coil, with respectively a first magnetized pole positioned in the vicinity of the median plane separating the two moving members and containing the axis of the coil, and a second and third magnetized pole arranged laterally on either side of the moving members, between the moving members and the coil.
