摘要： The present disclosure relates to an electromagnetic actuator of the type producing a force due to the current that remains substantially constant over the entirety of its useful travel Y and that has a low force in the absence of current, including at least one stator structure, at least one electrical supply coil, and a moving member, the stator structure having, on the one hand, a central pole running perpendicular to the direction of the travel Y and having a width YC1 in the direction of the travel and terminating at its end in a width YC2 that is greater than or equal to the travel Y of the moving member, YC2 being greater than YC1, and, on the other hand, two lateral poles having widths YL1 in the direction of the travel and terminating at their end in a width YL2 greater than YL1.
