Electromagnetic actuator with at least two coils

The actuator has recall and maintaining units (21, 23B), an electrical current regulation unit (22) and a control subunit (24) for controlling voltage provided to windings (L1, L2) during actuator closing operation, and for controlling a winding switching unit (10) to place the windings in parallel mode to generate recall magnetic flow to close the actuator. The units and the subunit control current provided to the windings during maintenance operations of the actuator in close position, and control the unit (10) to place the windings in serial mode to generate maintenance magnetic flow. The windings are cylindrical and aligned along same longitudinal axis.
