Definitions

  • the invention relates to a permanent magnetic drive according to the preamble of claim 1.
  • Such a drive is for example from the DE 43 04 921 C known.
  • the yoke or the core is formed by two U-shaped yoke halves, in which the armature is guided longitudinally displaceable.
  • the anchor according to the DE 43 04 921 C is laminated.
  • the object of the invention is to further improve a permanent magnetic drive of the type mentioned, so that with improved efficiency, the production of the drive is simplified.
  • the anchor is made according to the invention of solid material; In order to avoid eddy currents, it receives slots which extend in the direction of movement and, in particular in the case of cuboidal anchors, are introduced into the material perpendicularly to the respective surface both on the broad side and on the narrow longitudinal side. It is advantageous for magnetic reasons to make the slots as narrow as possible.
  • these slots could also be filled with insulating material.
  • a particularly advantageous embodiment of the invention can be taken from the features of claim 4.
  • the tightening force can be optimized by a suitable embodiment of the width of the spacer between the Jochschenkelenden.
  • the spacer in the region of the bore have a widening, wherein in each bore depending on a Bearing part can be used, which is adapted to the serving as anchor guide rods bolt.
  • the yoke plates which abut perpendicular to the spacer, have in the region of the widening other leg dimensions;
  • patches are used, which, when the spacer is made of non-magnetic material, are made of ferromagnetic material. In this way it is achieved that the leg ends of the yoke plates are all the same length, so that a uniform Jochblechform can be used.
  • Another way of optimizing the tightening force is to change the anchor surfaces in the end regions adjacent to the yokes, in which according to claim 9, a stepwise constriction or according to claim 10, a stepwise broadening is provided. In this way, the transition area between the yoke plates to the anchor can be varied as needed.
  • Another way to optimize the tightening force is to use a ferromagnetic spacer with a stepped constriction or broadening.
  • the yoke plates are made according to a preferred embodiment of an iron with low silicon content. As a result, the saturation polarization increases and the same yoke cross section can be used for higher holding forces. Loss of magnetization losses, which are generally reduced by high silicon content, are of little importance here, since they are already sufficiently reduced by the lathed design of the yoke.
  • the yoke plates are composed of two U-shaped punched Jochblechabitesen that are set with the free leg ends, if necessary, with the interposition of the intermediate piece against each other.
  • each yoke plate closed in a ring of a single sheet metal part whereby the intermediate pieces are eliminated.
  • the bolts or the armature guide rods are then guided in bearing bushes, which are inserted directly into the transverse webs, which extend perpendicular to the direction of movement of the armature.
  • the individual sheets are layered, preferably welded together in the region of the transverse webs, and then the holes are introduced, in which the bearing bushes are used. The welding of the individual sheets then has to be done so that a bore can be introduced without the plates move against each other.
  • the permanent magnetic drive 10 owns, like out Fig. 2 it can be seen, a yoke 11, which is composed of two yoke parts 12 and 13. Both yokes 12 and 13 have a substantially U-shape with a Jochsteg 14 and two yoke legs 15 and 16; the yoke legs 15 and 16 of the two opposing yokes 12 and 13 are directed against each other and placed with the interposition of an intermediate piece 17 and 18 against each other. In the middle between the yoke legs 15 and 16, the yokes 12 and 13 have parallel to the legs 15 and 16 extending serving as pole leg projections 19 and 20.
  • the armature 23 is composed of two anchor parts 26 and 27.
  • On the anchor part 26 are a first armature guide rod 28 and the anchor member 27, a second armature guide rod 29, which pass through holes 30 and 31 in the intermediate pieces 17 and 18.
  • the anchor 23, the in Fig. 3 As shown in one piece, has an upper armature guide rod 28 and a lower armature guide rod 29. It is formed of a cuboid, solid material, which is provided to avoid eddy currents with slots 32 and 33.
  • the slots 32 and 33 extend perpendicularly from the narrow side surfaces 34 and 35 inwardly to the central axis defined by the armature guide rods 28 and 29; the slots 33 are perpendicular to the broad side 36 and 37, wherein the slots 32 pass through the entire anchor line in the direction of movement P, whereas the slots 33 at a distance from the side surfaces 38 and 39, where the armature guide rods 28 and 29 connect ends; the slots 33 then do not interrupt the side surfaces 38 and 39.
  • the slots 32 and 33 serve to reduce eddy currents within the solid material anchor.
  • the 4 and 5 show two different views, for example, the intermediate piece 17.
  • the intermediate piece 17 has a bore 40 in its center, within which a bearing bush 41 is inserted, which serves to guide the armature guide rods 28 and 29.
  • the intermediate piece 17 is elongated narrow and has in the region of the bore 40 on both sides of a widening 42 and 43rd
  • yoke plates 44 and 45 are required. Those yoke plates which end in the region of the widening 42 and 43 are shorter than the yoke plates 44.
  • an intermediate layer 48, 49, 50 and 51 whose thickness corresponds to the step depth t, so that then the length of the yoke legs 52 over the entire length or width of the intermediate piece 17 may be equal.
  • the intermediate piece 17 may be made of non-magnetic material; then the spacers 48 to 51 are formed of ferromagnetic material.
  • the holding force can be optimized in this way by changing the area A taking into account saturation effects.
  • the optimum width of the intermediate piece is narrower than the required width for the anchor guide.
  • armature 60 is provided with a step 61 and 62, so that the end face 63 of the armature is smaller than the cross-sectional area of the remaining area, or it exists the ability to provide the end portions of the armature 70 with spacers 71 and 72, so that the end face 73 of the armature is larger than the rest of the cross section.
  • the intermediate piece 17 may be made of ferromagnetic material.
  • the yoke 11 is according to Fig. 2 composed of two yoke parts 12 and 13, which are approximately U-shaped and are pressed with the interposition of the spacers 17 and 18 against each other.
