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.

Electric motor with stator and mobile armature with suspending leaf springs which prevent movement in transverse direction and is in airgap plane that is perpendicular to first loop plane

A ripple diaphragm circulator includes a body inside which there is an internal chamber comprising an inlet opening and an outlet opening for fluid; and a flexible diaphragm placed in the chamber so as to be able to ripple there. The circulator further includes an actuating mechanism including at least one motor and a mechanical linking part linking the motor to the first edge of the diaphragm so as to move it in a reciprocating motion. The circulator also includes a device for detecting at least one value representative of a movement of the diaphragm, a power supply unit delivering an electrical power supply signal to the motor according to a detection signal.

The invention concerns a blade () designed to be fitted to the rotor of a rotating machine, said blade being characterized in that it exhibits a modular construction including: a rigid, median module () formed by a coffer (), which is itself formed by joining two side panels () that are connected to one another by at least one side rail (), the side panels () being connected by at least one weld executed on an internal protuberance on the said side panels that is set back from the intrados () and the extrados (E) of the blade (), an upstream module () forming a leading edge and added onto the upstream portion of the median module, a downstream module () forming a trailing edge and added onto the downstream portion of the median module. Blades for rotating machines and corresponding fabrication methods.
