Definitions
- -Electromagnetic actuator comprising a solenoid coil integral with a permanent magnet, and method of assembling such an actuator
- the invention relates to an electromagnetic actuator having an electromagnet whose coil is so ⁇ lidaire a permanent magnet, and a method of assembling such an actuator
- Electromagnetic actuators comprising a movable actuating member under the action of at least one electromagnet comprising a coil associated with a core arranged to channel a magnetic flux generated by the coil so that it closes in the actuating member, the coil comprising a coil of conductive wire covered with a casing and one electromagnet comprising at least one permanent magnet arranged relative to the core so that it can channel a flux generated by the permanent magnet so that it closes in the actuating member.
- the actuator assembly therefore requires mani ⁇ puler many independent elements, which complicates 1 assembly.
- the invention relates to an electromagnetic actuator whose assembly is simplified.
- an electromagnetic actuator of the aforementioned type in which the envelope of the coil includes at least a portion of the magnet per ⁇ manent so as to secure the permanent magnet the winding of conductive wire, so that the coil of conductive wire and the permanent magnet form a unitary unitary assembly adapted to be attached to the core.
- the invention also relates to a method of assembling an actuator comprising an actuating member and an electromagnet comprising a core, a coil comprising a winding of conductive wire and an additional element, which comprises the step of solidari ⁇ add the additional element to the coil prior to assembling the coil and core.
- the actuator of the invention comprises two electromagnets 1 arranged facing each other and each comprising a core 2 made of a stack of sheets made of ferromagnetic material. than.
- the upper electromagnet core appears only in the form of a silhouette in phantom.
- the electromagnets 1 are integrated in a casing 50 obtained by overmolding the cores 2.
- Each of the cores 2 comprises branches which are separated by recesses which form a housing in which a coil 3 extends.
- the sheets forming the cores 2 are cut to allow insertion into the core of perma ⁇ nent magnets 4.
- the magnets permanent 4 separate the sheets of the core 2 into three independent portions forming as many packages of sheets.
- the actuator further comprises a pusher 7 the the
- the pusher 7 has a free end protruding from the housing 50 and intended to cooperate with an element to be actuated, for example a distribution valve of a heat engine, while the other end of the pusher 7 is secured to a pallet 8 which extends between the electromagnets 1.
- the plate 8 is movable between two extreme positions in which the pallet 8 is in contact with one of the cores 2 of the electromagnets 1, under the effect of the electromagnets 1 which selectively attract the pa ⁇ lette and secondly of unrepresented springs which act on the pusher 7 to recall it to a position of equilibrium substantially halfway between extreme positions.
- Each of the coils 3 comprises an envelope 20 covering a winding of conductive wire 21.
- the envelope 20 protects the conductor wire 21 and prevents any electrical contact between the latter and the corresponding core 2.
- the casing 20 also makes it possible to improve the thermal continuity between the coil 3 and the corresponding core 2, by increasing the exchange surface between these two elements.
- the envelope 20 comprises protuberances 22 which extend to receive the extremities of the permanent magnets 4.
- the protuberances 22 so ⁇ lidarise the permanent magnets 4 to the coils so that the coil and the magnets form a unitary unitary assembly.
- a non-conductive material for example a polymer
- a non-ferromagnetic material for example aluminum
- the invention is not limited to the particular embodiments described above, but on the contrary encompasses any variant within the scope of the invention as defined by the claims.
- the illustrated actuator comprises two electromagnets
- the invention also applies to an actuator comprising only one electromagnet.
- the protuberances cover only a part of the permanent magnet (in this case, in the example illustrated, the end of the magnets)
- the envelope may include the totality of the additional element.
- the permanent magnet may be secured by means other than a protrusion, for example by a boss of the envelope.
