Definitions
- the invention relates to a magnetic linear drive with a first iron core, which passes through a first current-carrying coil and at least one magnetic flux enforced by a magnetic gap and having a first permanent magnet having movable armature, wherein in a first end position of the armature of the first permanent magnet at least partially fills a gap of the first iron core.
- a magnetic linear drive is known, for example, from European Patent Application EP 0 867 903 A2.
- the local linear drive serves to move a contact piece of an electrical switch.
- a movable armature has a permanent magnet, which moves in the direction of the coil during energization of an electrical coil due to the force acting between the permanent magnet and the energized coil magnetic forces. This movement is used to switch on a breaker unit of the circuit breaker.
- spring packages are tensioned.
- the permanent magnet adheres to an iron core.
- a magnetic linear drive of the type mentioned is known for example from DE 39 42 542 A1.
- a permanent magnet is moved along an axis by a coil which can be charged with current.
- the end positions beats the permanent magnet each at so-called stop poles.
- the distance of the movable armature is limited.
- An impact occurs relatively undamped and abrupt. This can cause vibrations, which shorten the life of the magnetic linear drive.
- the invention has the object of providing a magnetic linear drive of the type mentioned in such a way that in a simplified construction a possible low-vibration positioning of the armature is made possible in an end position.
- the object is achieved in a magnetic linear drive of the aforementioned type according to the invention that in a first end position of the armature of the first permanent magnet at least partially fills a gap of the first iron core and a yoke disposed on the armature rests against an edge of a gap of the first iron core.
- An iron core can consist of various suitable materials which have ferromagnetic properties (for example iron, cobalt, nickel, core sheets of special alloys).
- the at least partial filling of a gap in the first iron core by means of a permanent magnet permits a transition of the magnetic field lines emanating from the permanent magnet into the first iron core with low losses. Due to the abutment of the yoke at the edge of a gap, the guidance of the magnetic flux is improved by the magnetic flux is also guided within the yoke. The reluctance results in a force effect. The force effect is particularly great when the distance between the yoke and iron core is minimized.
- the gap which fills the permanent magnet, as well as the gap, at the edge of which the yoke is applied, one and the same gap or are also different from each other column.
- the magnetic flux generated within the first iron core is so strong that the armature is held in its final position. It can only be moved out by an external force or by energizing the coil.
- the first iron core consists of at least two sections, between which gap (s) is / are formed, which is enforceable by a magnetic flux producible in the first iron core.
- the division of the iron core into at least two sections allows advantageous guidance of the magnetic flux in the interior of the first iron core.
- the iron core can be designed in one piece, wherein the iron core itself is subdivided into a plurality of sections by a corresponding arrangement of cuts. The incisions are then regarded as a column in which, for example, the first permanent magnet is moved with the armature.
- specific regions can be specifically designed on the iron core, at which the magnetic flux extends in preferred directions, for example in order to be able to enter or exit perpendicular to a surface.
- the first iron core is formed at least in two parts and respectively pole faces are arranged on a first core body and on a second core body of the first iron core, between which a first and a second gap are formed.
- a division of the first iron core into a plurality of core bodies allows a modular assembly of the first iron core.
- different iron cores can be formed from a small number of core bodies.
- two identical core bodies may be used, between which a first and a second gap are formed.
- the two core bodies are configured as U cores, with the free ends of the legs being arranged opposite one another on the front side. The end faces of the legs then form the pole faces. Between Pol vom each having a first and a second gap is formed.
- the legs of the U-shaped core body are adapted to receive the first current-exciting coil and serve as attachment points of the yoke.
- a further advantageous embodiment can provide that in the first end position of the armature, the yoke is held by a magnetic flux emanating from the first permanent magnet.
- a further advantageous embodiment can provide that in the first end position, a magnetic force caused by the magnetic flux acts against a force emanating from an additional element.
- An additional element may for example be an elastic element, which is tensioned during a movement of the armature in the first end position.
- Elastic elements are, for example, springs, hydraulics, pneumatics, etc.
- the holding force of the armature caused by the magnetic flux is greater than the force exerted by the elastic element.
- the held by the elastic member force is now available to move the armature from the first end position.
- the impetus for a move out The outer force required for the armature from the first end position only has to have an amount which is greater than the difference between the magnetic force and the force exerted by the elastic element.
- the external force can be generated for example by energizing the electric coil.
- a magnetic field can be generated, which passes through the gap transversely to the direction of movement of the armature.
- a magnetic field oriented transversely to the direction of movement of the armature can be generated, for example, by winding the coil onto a leg of a U-shaped core body. This makes it very easy to replace the coil itself and the effect of the magnetic field generated by the first coil is directly amplified by the iron core. It can also be provided, for example, that the coil extends on two opposite sides of a gap of the iron core. Thus, a symmetrical force is generated at the gap or on the permanent magnet. In this case, the magnetic field in the gap can preferably run perpendicular to the direction of movement of the armature.
- a further embodiment may advantageously provide that the armature has a second permanent magnet which cooperates with a second iron core interspersed with a second current-carrying coil, which has at least one magnetic gap which can be penetrated by a magnetic flux, wherein a magnetic gap of the second iron core is in a second end position of the armature is at least partially filled by the second permanent magnet and the yoke bears against an edge of a magnetic gap of the second iron core.
- the magnetic flux generated by the first or by the second permanent magnet can be used to provide the holding forces.
- a reinforcement of the forces available for moving the armature is made possible in a simple manner.
- one or both coils can generate a force effect on the armature.
- this makes it possible to increase the drive power or to produce the same drive power with two smaller-sized coils as with a single coil.
- it is possible to dispense with the elastic elements which provide a restoring force.
- elastic elements continue to be used, for example, to effect an emergency breaking capacity or braking or additional acceleration of the armature.
- the yoke in the first end position at an edge of a gap of the first Iron core and in the second end position abuts an edge of a gap of the second iron core.
- the yoke on the first iron core and on the second iron core serves as a mechanical stop.
- the yoke is designed with sufficient mechanical stability to absorb the impact and abutment forces.
- the iron cores and the yoke are mechanically stable as bearing elements and keep vibrations away from the coils.
- a mirror-symmetrical design makes it possible to construct the drive in a modular way and to use similar modules.
- the mirror axis may, for example, be parallel or congruent with the axis of movement of the linearly displaceable armature.
- a further advantageous mirror axis may, for example, be an axis perpendicular to the direction of movement of the armature. With such a shape, it is possible to design the first and second iron cores in a same manner. This makes it possible to produce drives of different shapes with few components.
