LINEAR ELECTROMAGNETIC ACTUATOR COMPRISING TWO INDEPENDENT MOVING MEMBERS

摘要

The invention relates to a linear electromagnetic actuator comprising a stator (1) excited by at least one electric coil (2) arranged around an axis of symmetry (15) and two ferromagnetic stator poles (13, 14) positioned axially on either side of the coil (2), as well as at least two independent moving members (7), each of said moving members (7) being formed of a ferromagnetic material, characterized in that said linear electromagnetic actuator comprises at least three magnetized poles (4.5) arranged inside the coil (2), with respectively a first magnetized pole (4) positioned in the vicinity of the median plane separating the two moving members (7) and containing the axis (15) of the coil (2), and a second and third magnetized pole (5) arranged laterally on either side of said moving members (7), between said moving members (7) and the coil (2).
