20090027823 | Electromagnetic actuator with at least two windings - An electromagnetic actuator comprises a yoke, a core, at least two windings and switching means of the windings from a series position to a parallel position and vice-versa. It comprises control means comprising regulating means of the electric current flowing in the windings. The control means comprise inrush means controlling the voltage supplied to the windings during a closing operation, and controlling the switching means to place the windings in parallel mode. The control means also comprise holding means controlling the current supplied to the windings during a holding operation of the actuator in the closed position and controlling the switching means to place the windings in series mode. | 01-29-2009 |
20120293287 | Electromagnetic Actuator With Magnetic Latching and Switching Device Comprising One Such Actuator - An electromagnetic actuator comprising a core moving between a latched position and an open position, a permanent magnet, a coil designed to generate a first magnetic control flux to move the core from an open position to a latched position, and a second magnetic control flux designed to facilitate movement of the moving core from the latched position to the open position. The permanent magnet is positioned on the moving core so as to be at least partly outside the fixed magnetic circuit in which the first magnetic control flux flows in the open position, and to be at least partly inside the fixed magnetic circuit used for flow of a magnetic polarization flux of the magnet in the latched position. | 11-22-2012 |
