Electric motor with undulating membrane for watercraft

Flange for electric motor

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.

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 present invention relates to an undulating-membrane fluid circulator having an intake port (), a pump housing () delimiting a propulsion chamber (), a discharge port (), and an undulating membrane () paired with a drive means permitting an undulating movement of the membrane () between the upstream () and downstream () edges thereof, the undulating membrane () being capable of moving a fluid towards the discharge port (). According to the invention, the circulator further comprises at least one means () for guiding the fluid, said means being disposed in the fluid propulsion chamber () near one of the edges () of the undulating membrane () and making it possible to channel the fluid flow in a direction substantially parallel to the displacement of the wave along the membrane ().
