| 摘要 |
The invention relates to an electromagnetic actuator having a magnetic generator comprising a coil surrounding a mobile magnetic core (4) capable of moving by means of the magnetic field generated by the coil, said core being guided between an inoperative position and operative positions. Said actuator is characterised in that it comprises at least two coils (2, 3) connected to first (6) and second (7) independent control means, respectively, at least one primary coil (2) being managed by the first control means (6) with a view to controlling the movement of the mobile core (4), and at least one secondary coil (3) being positioned relative to the primary coil(s) (2) and actuated by the second control means (7) in order to modify the magnetic field generated by the primary coil(s) (2). |
