Definitions

  • the invention relates to an arrangement of magnetic bodies in a rotating drive device with a rotor and a stator.
  • the generation of rotary motions in drive devices is generally accomplished by appropriate juxtaposition of magnets and their activation to obtain a continuous mutual repulsion and to produce counteracting moments which do not inhibit repulsion. This has been achieved so far by periodically switching on and off of the magnetic flux in the rotor or stator.
  • An object of the present invention is to provide an arrangement in which the periodic interruption of the magnetic flux in the rotor or stator does not occur by switching on and off the generation of individual magnets. This object is achieved by the inventive arrangement of magnetic bodies and the shape of the rotor.
  • FIG. 1 shows an axial section through the drive device along line I-I in Figure 2
  • Figure 2 is a horizontal section along line II-II in
  • FIG. 1 A first figure.
  • Figure 3 is an axial section along line 1-7 in Figure 2
  • Figure 4 is an axial section along line 2-8 in Figure 2
  • Figure 5 is an axial section along line 3-9 in Figure 2
  • Figure 6 is an axial section along line 4-10 in Fig
  • Figure 7 is an axial section along line 5-11 in Fig. 2
  • Figure 8 is an axial section along line 6-12 in Fig. 2
  • Figure 9 is an axial section along line 1-7 in Figure 2 in working position with schematically shown
  • Figure 10 shows an axial section along line 1-7 in Figure 2 in the rest position with schematically shown
  • the drive device comprises a preferably cylindrical housing 1 in which a thrust bearing 3 carries an annular plate 5. On the plate 5 sits an annular, acting as a rotor magnet 7 with an annular bottom 8 and a cylinder jacket-shaped periphery.
  • the permanent magnet 7 is rotatably connected to the plate 5.
  • the connection is preferably made by a bond. Bonding, not only for attaching the magnet 7 to the plate 5 but for brittle magnetic materials, can also protect the magnet from destruction by the centrifugal and centripetal force at high speeds.
  • the magnet 7 forms the rotor of the arrangement.
  • the magnet 7 may also be inserted in a pot made of aluminum, which is fastened on the plate 5.
  • a plurality n of magnetic bodies 11 are arranged above the upper surface of the magnet 7, which is provided with a topography, suspended from a support plate 9 and arranged on a concentric circle with respect to the axis of rotation A of the rotor.
  • the magnetic bodies 11 are cylindrical and connected as electromagnets via a wiring 12 with a power source or preferably designed as a permanent magnet. If electromagnets for Use, these can be periodically switched on and off.
  • the magnetic body 11 may also be mounted axially displaceable against a spring 13 against the support plate 9 and enclosed with a jacket made of aluminum.
  • the support plate 9 in turn, together with the magnetic bodies 11 axially adjustable in the direction of the arrows P to make the distance a between the surfaces of the magnet 7 and the magnetic body 11 adjustable.
  • the adjusting device for the support plate 9 is not shown. You, ie the adjustment, can be done via a spindle or by a pneumatic or hydraulic cylinder.
  • the annular magnet 7 is in the example shown north N above and south S below.
  • the north poles N are at the bottom and the south poles S at the top.
  • the magnet 7 and the magnetic body 11 repel accordingly in the axial and horizontal directions.
  • the support plate 9 with the magnetic bodies 11 form the stator.
  • the stator could become the rotor and the rotor the stator. It is also possible to use the arrangement, i. instead of arranging the axis of rotation A of the rotor horizontally and supporting the rotor on two radial bearings (not shown).
  • a ring 17 made of MU metal is inserted in the upper area.
  • MU-metal is a metal alloy with which the magnetic field of a magnet can be shielded.
  • Such material is offered for example by the company VAC VACUUMSCHMELZE in Hanau (see also article about MU-metal production and applications in Wikipedia).
  • the ring 17 axially covers only a part, namely the inner circumferential surface of a spirally extending web 27. The latter will be described later in more detail.
  • the upper ring surface in the example of the north pole N of the magnet 7, is not flat, but has the cross sections of the magnet 7 shown in FIGS. 3 to 10. These cross-sectional shapes result from the topography of the magnet 7 designed according to the invention.
  • This topography results from a helical or approximately spiral-shaped axial first recess 19 with a base area 21 which tapers conically with respect to the axis A.
  • the first recess 19 begins at the point "12" (see FIG. 5, right) and its width increases continuously, in FIG Clockwise considered until its end at "9" reaches zero (see Figure 8, left).
  • a second recess 23 extends at a distance b radially within the first recess 19, wherein the Base 25 perpendicular to the axis of rotation A runs.
  • the radially outer wall of the first recess 19 thus has a lower height than the radially inner wall, which is bounded by the web 27.
  • the outside wall of the recess 19 is shortened by a conical third recess 29, which starts in the upper annular surface of the magnet 7 and starts at a distance C from the periphery ( Figure 4).
  • the inner end of the third recess 29 ends below the lying closest to the axis A lateral surface of the magnetic body 11.
  • the magnetic body 11 may also have a smaller diameter, so that no direct overlap with the web 27 takes place.
  • an output shaft which is rotatably connected via the plate 5 with the magnet 7, that is connected to the rotor.
  • the shaft 31 is preferably made of an inox material.
  • the magnet 7 may consist of a plurality of assembled smaller magnets, which are suitably connected to each other.
  • the device can also be operated with an arrangement of the magnetic poles N-S (attraction), instead of N-N or S-S.
