Definitions

  • the present invention relates to an electromagnet with movable equipment with permanent magnet, in particular for contactor.
  • the known electromagnets of this center comprise a movable assembly consisting of a permanent magnet and two pole pieces conducting the flux fixed respectively to each pole face of said magnet perpendicular to the magnetization axis of the magnet.
  • These pole pieces have arms projecting from the pole faces, and at least one of the pole pieces has arms whose ends are bent at right angles defining, with at least one arm of the other pole piece, two airgap zones cooperating with a cylinder head mounted on a coil which cooperates magnetically with the magnet.
  • These airgap zones are arranged on either side of the supply axis, said magnetization axis of the magnet being perpendicular to that of the coil, the fisxed yoke surrounding the two ends of the coil and planar parts of the cylinder head parallel to the magnetization axis each penetrating respectively into an air gap area so that, for at least one stable position of the moving element, a planar part of the cylinder head is in contact with one of the pole pieces while the other flat part is in contact with the other pole piece.
  • the cylinder head has been arbitrarily considered as carrying a fixed reference with respect to which the armature is movable. It goes without saying, however, that the movements of the cylinder head and of the armature seen in relation to other references may be different.
  • electromagnets are in rotary movement, others in translational movement. These are better suited for controlling contactors.
  • the parallelism and the nominal spacing of the plane parts of the cylinder head are dependent on the following tolerances: cambering angles in the cylinder heads, length of the core , crushing and perpendicularity of the crimps of the core on the cylinder heads, thickness of the cylinder heads.
  • cambering angles in the cylinder heads cambering angles in the cylinder heads
  • length of the core crushing and perpendicularity of the crimps of the core on the cylinder heads
  • thickness of the cylinder heads a correction of the bearing surfaces of the flat parts of the cylinder heads cannot be carried out when the coil is in place.
  • the present invention aims to produce an electromagnet which, by eliminating the aforementioned drawbacks, provides improved magnetic coupling between the coil, the air gaps and the permanent magnet, and a higher efficiency.
  • the moving assembly is located inside the coil and that guide means are provided to allow its translational movement along the axis of the coil so to form a plunger core.
  • the core of the coil has a substantially rectangular section occupied by the magnet and the pole pieces; the airgap zones are arranged at the two ends of the coil, and the fixed cylinder head is parallel to the axis of the coil and situated outside the coil so as to magnetically join together the flat parts of the cylinder head .
  • the entire flux of the coil is used to counter the flux of the permanent magnet.
  • the entire flux of the permanent magnet cooperates with the flux of the coil.
  • the location of the plunger core makes it possible to ensure precise guidance in a simple manner.
  • each pole piece forms two arms extending respectively on either side of the axis d magnetization. At least one pole piece has ends of its arms bent at right angles and the ends of one pole piece are cambered beyond the arms of the other pole piece relative to the magnetization axis.
  • the first pole piece envelops the second and its cambered ends are outside the cylinder head, while the ends of the second are inside the cylinder head.
  • the first pole piece in one position, touches a flat part of the cylinder head, while the other pole piece touches the other flat part of the cylinder head. In the other position, the roles of the flat parts of the cylinder head are reversed with respect to the pole pieces, and there are thus two stable positions.
  • a first pole piece forms a single arm extending on a first side of the axis d magnetization, while the other pole piece has, on the first side of the magnetization axis, an arm the end of which is arched at right angles beyond said single arm of the first pole piece with respect to the magnetization axis, and, on the second side of the magnetization axis, two magnetically joined arms, the ends of which are respectively bent at right angles one beyond the other with respect to the axis of magnetization.
  • the magnetic circuit In a first position, which is only stable, the magnetic circuit is closed by the single arm of the first pole piece and by the other pole piece. In the other position, the first pole piece remains off and this position is not stable.
  • the cylinder head comprises two U-shaped half-cylinder heads, which fit together in an adjustable manner so as to be able to adjust the spacing between the flat parts of the half-cylinder heads.
  • the movable assembly is preferably provided with a guide rod arranged along the axis of the coil, and sliding in bearings fixed on stirrups which are fixed respectively on each half-cylinder head.
  • the moving assembly comprises two magnets with parallel axes, between which the guide rod passes, and the magnets are immobilized by plates arranged perpendicular to the guide rod and comprising tongues crimped in holes or slots in the pole pieces.
  • a compression coil spring is disposed on the guide rod, between; on the one hand, the body of the movable assembly and, on the other hand, a washer applied by said spring against a shoulder of the guide rod, a fixed stop cooperating with said washer being provided to define the point of the stroke of the moving part where the spring begins its return action.
  • one of the pole pieces can have its arms arched opposite the axis of the coil, said. coil then comprising a winding produced on a frame formed by two separable half-frames before winding.
  • one of the pole pieces can have its arms arched, one towards the axis of the coil and the other in the opposite direction, the coil then comprising a monobloc frame.
  • the breech is in a U to at least partially wrap the ends of the coil, the pole piece furthest from the breech having its arms arched towards the breech to at least partially wrap the branches of the U of the cylinder head, and the other pole piece being straight.
  • the electromagnet comprises a coil 1 with its coil 2 wound along the axis 3 of the coil.
  • a fixed yoke 4 surrounds the coil going from one end of the core of the coil to the other end of this core.
  • this cylinder head comprises two half-cylinder heads: 4a, 4b in the shape of a U, fitting one into the other along the axis 3 of the coil. and held together by screws 5.
  • Elongated holes 5a made in one of the half-cookers allow this interlocking to be adjusted.
  • a plunger core capable of moving in translation along the axis 3 of the coil.
  • This plunger core is constituted by a movable assembly which comprises, on the one hand, a permanent magnet 6 arranged so that its magnetization axis 7 is perpendicular to the axis 3 of the coil and on the other hand two pole pieces flux conductors 8 and 9, fixed respectively to each pole face, N, S of the magnet 6, perpendicular to its magnetization axis 7.
  • Each pole piece 8, 9 has two arms 10a, 10b and respectively 11a, 11b projecting of the polar faces N, S of the magnet 6.
  • the magnet 6 consists of two magnets 6a, 6b with axes 7a, 7b for purely constructive reasons. In what follows, all of these two magnets will generally be designated by the reference 6 for convenience.
  • the arms of the pole pieces are bent at right angles to the axis 3 of the coil, by determining parallel ends 12a, 12b and respectively 13a, 13b. More precisely, the ends 12a, 12b of the pole piece 8 are located respectively beyond the ends 13a, 13b of the pole piece 9 with respect to the magnetization axis 7.
  • a guide rod 17 is made integral with the movable assembly and is guided along the axis 3 of the coil by bearings 18 fixed on stirrups 19, themselves fixed on each half-yoke 4a ⁇ 4b by screws.
  • the guide rod 17 passes between the magnets 6a, 6b (FIG. 2) and passes right through the mobile assembly while being fixed to the latter by nuts 20 (FIG. 1).
  • the core of the coil 1 has a substantially rectangular section (Figure 2), almost filled with magnets and pole pieces.
  • the closed air gaps 12a-14a and 13b-14b give forces in the same direction which keep the moving element in its extreme low position.
  • the pole piece 109 here has only one arm 111a, arched at 113a.
  • another arm 110c parallel to the arm 11 Ob of the pole piece 8, another arm 110c has been added magnetically joined to the arm 110b and having an end 112c bent at a right angle so as to be in the plane which the end previously occupied. 13b of the arm 11b in the embodiment of FIG. 1.
  • the pole piece 209 is rectilinear and has no arched ends, the surface of the air gaps being given directly by the edge (or cross section) of the arms 211 a and 211 b.
  • the decrease in the airgap area gives a greater slope to the force curve as a function of the stroke, which may be acceptable or desirable in. certain cases.
  • the ends. curved 212a and 212b of the pole piece 208 are curved outward with respect to the axis 203 of the coil. It follows that the forces are generated further from the axis 203, but the corresponding torque can be collected by the guide rod 217. On the other hand these outward curvatures require for the assembly to realize the framework of the coil 201 into two separable parts before winding.
  • the air gap 12a-14a of FIG. 1 is now replaced by an air gap 212a-214a, the flat part 214a of the half-yoke 204a being at the same level as the flat part 14a of FIG. 1.
  • air gap zone therefore remains valid if these zones are defined with reference to the magnetization axis 7 or 207.
  • This arrangement limits the leakage flow between the pole pieces 208 and 209 and it facilitates the installation of a return spring.
  • a coil spring 222 is disposed on one end of the guide rod 217. This spring is compressed between the plate 215a and a washer 223, itself abutting on an elastic ring 224 inserted in a groove of the rods guide 217. Another elastic ring 225 can replace the nut 20 of FIG. 1.
  • the bearing 218a can be screwed more or less deeply on the stirrup 219a and locked by a nut 226.
  • a shoulder 227 of the bearing 218a serves as a fixed stop for the washer 223, in. the movement of the latter towards. the corresponding end of the race. It can therefore be seen that the moment of travel can be adjusted when the spring 222 exerts its restoring force on the moving assembly.
  • pole piece 309 has only one arm. 311a, and la. pole piece 308 has a third arm 310c magnetically joined to the arm 310b.
  • the curvature 312a of the pole piece 308 is still directed towards the outside, but the curvature 312b is directed towards the inside as well as the arm 310c. This arrangement facilitates mounting and allows the use of a one-piece coil frame.
  • the cylinder head 404- comprises a single U-shaped part which at least partially envelops the ends of the coil 401, the ends of the branches of the U constituting flat parts 4.14a, 4-14b.
  • the moving equipment is analogous to. that shown in Figure 3, with this difference quie, if the pole piece 408 has arms 410a, 410b, arched at 412a, 412b so as to wrap the branches 414a; 414b of the U of the cylinder head, the pole piece 409 is rectilinear as in the case of FIG. 4 and only works by the song of the arms 411 a, 411 b.
  • the clearance between the moving part and the reel is expected to be very small, so that it is the framework of the reel which serves as a guide for this crew.
  • Elastic blades. 430 of non-magnetic material are attached to the cylinder head to play a role. reminder.
  • the electromagnet is bistable. We could make it monostable by the modifications exposed above.
