Definitions

  • the invention relates to a monostable electromagnetic rotary armature relay with two armature legs, which are connected via a ferromagnetic center piece and each form a working air gap with two laterally opposed yoke legs of an excitation coil.
  • a polarized rotating anchor system monostable (DT-AS 24 54 967).
  • DT-AS 24 54 967 Such a relay has one so-called H-armature with two parallel ferromagnetic webs and at least one permanent magnet in between. It was proposed to arrange the ferromagnetic webs offset by a certain section of their length in relation to one another in order to bring about monostable switching behavior, so that pole surfaces of pole shoes and armature webs of different sizes lie opposite one another.
  • this measure alone cannot ensure a monostable switching behavior. Rather, a monostable characteristic must also be brought about in this case by additional means, such as separating plates and additional springs attached on one side.
  • the object of the invention is to design a rotary armature relay of the type mentioned at the outset by polarizing the armature so that a clear monostable switching behavior is achieved without additional reset means.
  • this object is achieved in a relay of the type mentioned at the outset in that a pole piece is arranged parallel to each of the two armature legs, which is magnetically coupled to the armature leg in question and, together with this, forms the associated yoke leg in the form of a plier, forming a further working air gap, where at least one of the pole pieces is magnetically coupled to the parallel armature leg via a permanent magnet.
  • the arrangement of the pole pieces on the armature according to the invention causes the two pole pieces to lie essentially in series in the flux circle of the permanent magnet or magnets.
  • the armature then assumes its rest position when the two pole pieces lie against the yoke legs, so that the continuous flow circuit can close via the yoke.
  • the armature is expediently provided with two permanent magnets, so that both pole pieces are each coupled to the associated parallel armature leg via a permanent magnet.
  • the polarity of the permanent magnets is chosen so that both are in series in the same direction over the middle part of the armature.
  • the magnetic asymmetry of this monostable relay is determined by the magnetic resistances> between the ferromagnetic center piece of the armature and the two pole pieces.
  • the idea of the invention is of course also realized if, instead of a continuous air gap, a ferromagnetic intermediate web is present between the pole pieces and the middle piece, the magnetic resistance of which ensures sufficient asymmetry of the forces.
  • the coupling of the center piece to the two armature legs must be selected appropriately, with various possibilities, from ferromagnetic coupling to continuous air gaps, also being considered here.
  • an embodiment is also possible in which only one pole piece is coupled via a permanent magnet and the other pole piece is connected ferromagnetically to the center piece or the associated armature leg.
  • the bearing point could also be arranged offset from the center between the two arm legs, the length of the arm legs and the air gaps also being able to be different.
  • FIG. 1 shows the magnet system for a monostable rotary armature relay. It contains an excitation coil 1, the core 2 of which forms two yoke legs 3 and 4. In the middle between the ends of the yoke legs 3 and 4, an armature 6 is arranged on an axis of rotation 5, which armature consists of two armature legs 7 and 8 arranged symmetrically to the axis of rotation 5 and a ferromagnetic center piece 9. This center piece 9 is magnetically connected to the armature legs 7 and 8 in a suitable manner via the coupling surfaces 9a and 9b.
  • the armature legs 7 and 8 with the middle piece 9 can consist of an iron piece, or in another case the coupling surfaces 9a and 9b can be designed as air gaps.
  • the armature leg 7 forms with the yoke leg 3 a working air gap S1
  • Two permanent magnets 10 and 11 are used to reset the armature, which are each arranged on the armature legs 7 and 8 and each carry a pole piece 13 and 14 parallel to the associated armature leg.
  • This Pole pieces together with the parallel armature leg form approximately pliers-shaped the respective end of the associated yoke leg 3 or 4.
  • the pole piece 13 with the yoke leg 3 forms a further air gap S3 and the pole piece 14 with the yoke leg 4 forms the further air gap S4.
  • the two permanent magnets 1o and 11 are polarized so that they are magnetically in series over the center piece 9 of the armature 6.
  • 0 1 means the excitation flux generated by the coil; it is drawn as a continuous line.
  • the asymmetry of the magnet system arises from the fact that in the working air gaps on the idle side, i.e. in the air gaps S3 and S4, there is always a greater continuous flow than in the working air gaps S1 and S2 on the working side of the armature.
  • the two partial flows 0 11 and 0 12 of the permanent magnets add up, on the working side they subtract.
  • the magnetic resistances R1 between the center piece 19 of the armature and the pole pieces 13 and 14 determine this asymmetry. Together with the magnetic resistor R2 in the symmetry zone (area around the bearing point) of the center piece 19 and the magnetization states of the magnets 11 and 12, these magnetic resistors R1 are to be dimensioned in such a way that an optimal adaptation to the set of springs occurs.
  • the magnetic resistors R1 and R2 can be both air gaps and iron cross sections of a suitable dimension.
  • the force-displacement curve of the magnet system shown in FIGS. 1 and 2 is shown in FIG. 3.
  • the force P is plotted over the path s.
  • the magnet system curves are designated by m and the spring rate curve by f.
  • the spring set is completely symmetrical, so curve f goes exactly in the middle between the rest side R and the working side A through the zero point.
  • the magnet system curve lies below the spring rate curve f; the anchor is pulled to working side A.
