Abstract
An electromagnetic machine includes a stator, a movable armature and a device for mechanically connecting the movable armature to the stator. The connecting device includes a plurality of leaf springs. The stator includes at least one first electrical coil and at least one first magnetic core forming at least one open loop between first and second terminal ends of said first loop in order to define an air gap between said terminal ends. The plurality of leaf springs extends on a single side of an air gap plane perpendicular to a first loop plane. The plurality of leaf springs is arranged so as to authorise the translation of the movable armature in relation to said stator in a direction that is perpendicular to the loop plane and to prohibit any movement of said movable armature in any direction within said loop plane.
