Definitions

  • the invention relates to the field of electromagnetic actuators.
  • So-called self-holding magnets are generally known and used (see e.g. E. Kallenbach, R. Eick, P. Quendt, T. Ströhla, K. Feindt, M. Kallenbach: Elektromagnete (2008), chap. 9.2 Polarized magnets, p. 298 ).
  • the shunt reduces on the one hand the electrical power required to compensate for the field generated by permanent magnets; on the other hand, the permanent magnet or magnets are protected from demagnetization.
  • self-holding magnets are combined with springs and together with these they form electrically triggered spring accumulators.
  • the spring thus acts on the armature in order to open the working air gap or gaps.
  • the self-holding magnet is designed in such a way that if the air gap falls below a certain minimum, a residual air gap remains to hold the spring in the tensioned state.
  • magnets locking units
  • a self-holding magnet according to the preamble of claim 1 is from WO 99/33078 known. Further self-holding magnets are off DE 10 2011 014192 A1 , DE 943 479 C , U.S. 6,130,594 A , GB 765 411 A , U.S. 3,444,490 A and U.S. 2,130,870 A known.
  • a low trip current is particularly desirable in battery operated locking units.
  • Trip devices, especially residual current trip devices should also react as quickly as possible, that is to say have short dead times.
  • Such triggers must also be designed in such a way that excessive counter-excitation does not inadvertently prevent or slow down the triggering inadmissibly:
  • An overcompensation of the permanent magnetically generated field and thus the associated holding force can namely cause a holding force to develop as a result of the Result in a linked flux tripping current, so that the self-holding magnet triggers delayed or not at all.
  • Trigger magnets must of course be quite insensitive to vibrations, unintentional triggering as a result of blows or other vibrations should be made very difficult, which is why the desired high electrical sensitivity - i.e. the desired low trigger currents or outputs - cannot be easily achieved by magnetic holding force and spring force are aligned as closely as possible.
  • the invention is based on a self-holding magnet with a spring, the self-holding magnet having a stop for the armature and a magnetic shunt.
  • the armature of the self-holding magnet In the tensioned state, the armature of the self-holding magnet is held permanently magnetically against the spring force, the working air gap (or the working air gap, if an armature with several pole faces is used) is closed except for a (working) residual air gap given by the stop, whereby the frame of the self-holding magnet (as an anchor counterpart) itself can serve as a stop, if necessary with an anti-adhesive film or similar.
  • the shunt has a particularly low reluctance:
  • the shunt is to be dimensioned so that its reluctance in the clamped state is of the same order of magnitude and as large as possible as the reluctance of the (working) residual air gap (or the sum of the reluctances of the remaining working air gaps, provided that several working air gaps are connected in series; this is the case, for example, with pole plates where two poles act on the same surface).
  • the working air gap (s) and shunt are magnetically connected in parallel. However, they are connected in series with regard to the flux that can be generated by the coil.
  • the reluctance of the shunt is of the same order of magnitude as the reluctance of the (working) residual air gap and, if possible, the same size as this. Flux-carrying parasitic residual air gaps must also be taken into account according to their arrangement. In any case, an electrical counter-excitation of the self-holding magnet leads to the flux density in the Working air gap (s) is reduced while the flux density in the shunt increases.
  • the shunt partial circuit can also be designed with regard to the flux-carrying cross-sections occurring in it so that due to magnetic saturation the reluctance of the iron circuit "seen" by the coil increases with increasing counter-excitation so that even a comparatively strong counter-excitation does not hold the armature against the spring force able (because the flux density in the shunt increases with increasing counter-excitation).
  • the shunt pitch circle can have the smallest effective cross section possible over a certain (minimum) length.
  • the shunt can be defined geometrically; however, it can also be formed from a soft magnetic material with a comparatively low (macroscopic) permeability, in particular a sintered material with a distributed air gap, which can simplify production.
  • a self-holding magnet according to the invention also has a resilient stop.
  • the stop In conventional self-holding magnets with springs (“storage springs”), the stop can be regarded as rigid to a good approximation. In these drives, the armature only starts to move when, as a result of the electrical counter-excitation, the magnetic holding force falls below the acting (releasing) spring force of the storage spring. This is not the case if the stop is able to compress itself. However, in order to meet the requirement for low tripping capacities with sufficient insensitivity to vibrations, the residual air gap produced with the help of the stop should be small. Accordingly, the resilient stop should be of suitable rigidity: On the one hand, the stop should be much stiffer than the "first" spring of the self-holding magnet (“storage spring”) serving for elastic energy storage.
  • the resilient stop should be far less stiff than a solid stop (made of an iron material) would be.
  • the stop is 100 bis 10,000 times stiffer than the "first" spring (accumulator spring).
  • the stop should in no way have a linear characteristic, but can also be degressive, for example, and be built up with the help of spiral springs, in particular a disc spring.
  • the resilient stop can also be preloaded.
  • the stop can be configured to be adjustable, for example with a fine thread, so that its preload and / or rest position can be adjusted in order to match the triggering characteristics.
  • the "first" spring (storage spring) and the “second” spring, namely the resilient stop, together form a combined spring with a highly progressive characteristic curve, based on their effect on the armature.
  • the resilient stop allows a very small counter-excitation to cause a certain (small) movement of the armature. Since, however, according to the invention, the shunt has a very small reluctance, even very small deflections of the armature from its (closed, tensioned) initial stroke position result in the flow over the shunt increasing considerably and the flow over the working air gap (s) decreases noticeably, with the associated magnetic holding force naturally developing proportionally to the square of the flux density in the working air gap.
  • the self-holding magnet according to the present invention can further be a have the following configurations:
  • the reversing solenoid can have a variably designed shunt. This means that when the armature is detached - i.e. while the working air gap is still of the order of magnitude of its remaining air gap - a movement of the armature which increases the working air gap results in a reduction in the reluctance of the shunt.
  • the invention can be designed as a reversing stroke magnet, one end face of the armature forming the working air gap of the self-holding magnet together with the frame.
  • the opposite end of the armature can form the shunt, the shunt being designed as an armature-armature counterpart system, which is preferably designed so that the highest "force constant" occurs at the start of the stroke (i.e.
  • the armature is supplied with a permanent magnetically generated magnetic flux, which is distributed to the working air gap (without influencing the characteristic curve) and shunt (with influencing the characteristic curve, acts to open the working air gap) according to the associated reluctances.
  • the counter-excitation with the help of the associated coil then causes an increase in the reluctance force acting on the armature at the shunt and a decrease in the reluctance force at the "holding surface", ie at the working air gap.
  • the shunt and accumulator spring exert force on the armature in the same direction (to open the working air gap).
  • a reduction in the flux-carrying shunt air gap can also take place with the aid of a second armature (“shunt armature").
  • This anchor is movably arranged that it is able to close the shunt air gap, which is small anyway, except for a residual air gap.
  • the reluctance force acting on the shunt armature can be transmitted to the armature via a mechanical or hydraulic device with or without transmission to open the working air gap (the force on the "shunt armature” should therefore be applied in the same direction to the (working) )
  • Anchors of the self-holding magnet act like the force of the accumulator spring).
  • a simple plunger is suitable for power transmission.
  • the shunt armature In the tensioned state of the drive, the shunt armature is in a position in which the reluctance of the shunt is as equal as possible to the series reluctance of the (working) residual air gap (s). If a counter-excitation is now generated, the force acting on the shunt armature increases and is transferred to the (working) armature in the direction of the (storage) spring force acting on the (working) armature, i.e. it acts to remove it from its initial stroke position to solve. At the same time, the magnetic holding force is reduced by the counter-excitation. Movement of the armature and shunt armature ultimately causes a decrease in the reluctance of the shunt and an increase in the reluctance of the working air gap.
  • Fig. 1a and Figure 1b shows an exemplary embodiment for a self-holding magnet according to the invention with a spring, which has a shunt armature. A resilient stop is not shown, but can advantageously be added.
  • Fig. 1a shows a section through the approximately rotationally symmetrical drive. The drawing is not to scale, but offers the developer a good basis for FEM optimization. The exemplary embodiment serves only for explanation and is in no way to be seen as a restriction.
  • a coil body can be dispensed with if, for example, the groove in which the coil lies is coated with an insulating coating.
  • ⁇ 10 and ⁇ 11 are the working air gaps (connected in series) in the tensioned stroke start position and are therefore closed except for residual air gaps (not shown).
  • ⁇ 20 is the shunt air gap that is used by the shunt armature 21 to do work.
  • the inner frame part 31 is chamfered in the area of the working air gap ⁇ 10.
  • Figure 1b shows a top view of the drive with removed armature guide and removed working armature and ram.
  • the permanent magnets made up of radially polarized circular segments can be seen, which are located in recesses in the (soft magnetic) frame.
  • 33 are structural magnetic shunts, the magnets being dimensioned in such a way that these structural magnetic shunts 33 saturate, so that a magnetic tension occurs between the inner frame part 31 and the outer area with the outer frame part 30, 32 and flux return 41.
  • the construction with radially polarized circular segments, constructive (saturated) shunts, etc. is comparatively complex, but enables a particularly high dimensional accuracy and thus meets the basic requirement for small residual air gaps.
  • Secondary air gap ⁇ 20 is in the illustrated stroke start position (panned state) of the same reluctance as possible as the series connection ⁇ 10, ⁇ 11 (but with a larger cross section). From the point of view of the coil, this can result in a polarized (sic! Magnetic circuit with low reluctance, which enables large force constants (N / A).
  • the shunt anchor 21 acts via the driver 20 on the plunger 10 welded to the working anchor and thus additionally helps to maintain the holding force which is imparted via ⁇ 10 and ⁇ 11 overcome and accelerate the working anchor.
  • the (electrical) sensitivity of this drive can be further increased by equipping it with a resilient stop of suitable rigidity.
  • This stop (not shown) can, for example, make use of a plate spring and act on the plunger 10. Pre-tensioning the disc spring or changing its rest position, whereby the fine adjustment can be carried out by means of screws with fine threads, then enables the electrical sensitivity of the drive to be adjusted.
  • It can be advantageous to connect the drive according to the invention in series with a diode and to connect a varistor in parallel to the drive, because during opening a voltage is induced in the coil which is opposite to the trigger voltage. Such an external circuit can shorten the tripping time considerably.
  • triggering proceeds as follows: Electrical counter-excitation reduces the flow through working air gaps ⁇ 10, ⁇ 11 and increases that through the shunt air gap ⁇ 20.
  • the resilient stop even a minimal supply of current leads to a certain amount of rebound.
  • ⁇ 10 and ⁇ 11 increase, while ⁇ 20 decreases accordingly (since the shunt armature 21, accelerated by reluctance force, follows the plunger 10).
  • the air gaps mentioned are all small, this small deflection of the system - the rebound - leads to a markedly different distribution of the permanent magnetically generated flux:
  • the flow through the working air gaps ⁇ 10, ⁇ 11 decreases, that through the shunt increases.
  • the rapid increase in the force acting on the shunt armature 21 contributes to the triggering of the self-holding magnet and also enables a considerable shortening due to the additional force transmitted to the working armature 11 via the driver 20 and plunger 10 and the magnetic "short-circuiting" of the working air gaps ⁇ 10, ⁇ 11 the achievable actuating times, because in the vicinity of the stroke start position only small forces from the difference between the spring force and the reluctance force to accelerate the armature are available with conventional self-holding magnets, at least with low release powers.
  • the reluctance force inhibiting the armature movement is short-circuited with the associated flux as a result of the movement of the shunt armature, while the working armature 11 is driven by the reluctance force acting on the shunt armature 21 in addition to the spring force).
