Definitions
- the present invention provides
- FIGS. 10 and 11 and also FIGS. 13 to 16 add electrically excited magnets to already known permanent magnetic support / levitation arrangements in a manner which is suitable for adding the magnetic resistance within to change the magnetically partially saturated material so that a force arises which acts on the permanent magnet and thereby causes its movement.
- the present invention further provides
- the door leaves are provided at their upper ends with rollers which can be moved back and forth on a rail.
- the movement takes place by means of an electric motor, gear, belt or chains via deflection rollers.
- the electrical energy that the electric motor absorbs is converted into mechanical energy via an air gap on the rotor of the electric motor. In the present invention, this conversion takes place without inference through an air gap.
- Magnetic carrying or levitation systems are known from the TRANSRAPID high-speed train.
- the load (vertical) and its movement (horizontal) are carried by electronically controlled electromagnets, the electromagnetic force fields of which act on the moving vehicle via an air gap from the stationary track. In the present invention, this conversion occurs without inference through an air gap.
- US Patent 4,324,185 (Vinson) relates to a permanent magnet levitation and transport system.
- the arrangement consists of ferromagnetic material, permanent magnets and electrical coils.
- the movement arises from the fact that the electromagnetic force fields cause the permanent magnets to move via an air gap.
- magnetic saturation is not required for the movement and would even have a disadvantageous effect.
- the magnetic levitation system with permanent magnets DE 3719587 AI (Weh) relates to a combined carrying and guiding behavior, but in contrast to the present invention with the main purpose of generating lateral guiding forces and preventing the excitation part from migrating out of its central position.
- the object of the invention is to bring about a movement of the load with the greatest possible use of the components which have already been used for the floating and carrying effect, and with low energy and wear without any conclusion about an air gap.
- two ferromagnetic carrier profiles 1 which are arranged parallel to one another are mechanically connected to one another by means of electrical coils 3 with iron core 2 which are fixedly arranged and spaced apart from one another.
- at least one horizontally magnetized permanent magnet 4 is arranged between the mounting rails, the width of which is smaller than the clear width of the two mounting rails, so that an empty space is created.
- the magnet is to be guided centrally between the mounting rails by means of rollers, sliding material or other mechanical means.
- This arrangement creates a permanent magnetic levitation effect without first charging the electrical coils 3 with current.
- the dimensions of the mounting rail 1, permanent magnet 4 and coil core 2 are selected so that the mounting rail and coil core are in the state of partial magnetic saturation.
- the present drive system is characterized in that the coupling of the electromagnetic field with that of the permanent magnets takes place largely in the carrier profile and not in an air gap. This leads to a very small magnetic resistance of the entire system, an essential (positive) difference to rotating electrical machines in which the stator and rotor fields are coupled in the air gap (prior art).
- a ferromagnetic carrier profile 1 and a plurality of permanent magnets 4 are arranged such that a stable floating and wearing state of the permanent magnet group is achieved.
- the movement of the magnet group is achieved in that several electromagnets are arranged perpendicular to the carrier profile, the ends of the coil cores facing away from the carrier profile are each connected in pairs or continuously with a yoke 7 made of ferromagnetic material (FIG. 4 ). If the individual coils are charged with suitably polarized electrical energy, the magnetic saturation changes in the carrier profile by coupling the magnetic fields, which ultimately leads to a movement of the magnet group 4, 5.
- a ferromagnetic carrier profile 1 and a plurality of permanent magnets 4 are arranged such that a stable floating and wearing state of the permanent magnet group is achieved.
- the movement of the magnet group 4, 5 is achieved in that a plurality of electromagnets 2, 3 are arranged in parallel on the upper side of the mounting rail, the two ends of the coil cores being connected to the mounting rail with pole pieces 9 made of ferromagnetic material (FIG. 6).
- the magnetic saturation changes in the carrier profile by coupling the magnetic fields, which leads to a movement of the magnet group 4, 5.
- a ferromagnetic mounting rail 1 and a plurality of permanent magnets 4, 5 are arranged in such a way that a stable floating and wearing state of the permanent magnet group is achieved.
- the movement of the magnet group 4, 5 is achieved in that several electromagnets 2, 3 are arranged vertically on the mounting rail, the ends of the coil cores facing away from the mounting rail are connected in pairs or continuously to a yoke 7 made of ferromagnetic material (FIG . 8th). If the individual coils are charged with suitably polarized electrical energy, the magnetic saturation changes in the carrier profile by coupling the magnetic fields, which leads to a movement of the magnet group 4, 5.
- a ferromagnetic mounting rail 1 and a plurality of permanent magnets 4 are arranged such that a stable floating and wearing state of the permanent magnet group is achieved.
- the movement of the magnet group 4, 5 is achieved in that several electromagnets 2, 3 are arranged perpendicular to the mounting rail, the coil core ends of which are remote from the mounting rail are each connected in pairs to a ferromagnetic yoke 7 (FIG. 11).
- the coil pairs 3 connected by a yoke 7 are arranged at an angle overlap on the mounting rail.
- the magnetic saturation changes in the carrier profile by coupling the magnetic fields, which leads to a movement of the magnet group 4, 5.
- the oblique overlap of the coil arrangements enables a higher step accuracy, i.e. a more precise positioning of the movement.
- a horizontally aligned ferromagnetic carrier profile 1 and at least one permanent magnet 4 are arranged in such a way that the permanent magnet 4 is in a stable state of wear, with a support wheel 11 ensuring that the permanent magnet is spaced apart from the carrier rail.
- the movement of the permanent magnet 4 is achieved in that a plurality of electromagnets 2, 3 are arranged vertically on the opposite side of the support magnet 4, that is to say the upper side of the support rail, the coil core ends of which remote from the carrier profile are connected in pairs or continuously to a ferromagnetic yoke 7 are (Fig. 12, 13).
- the magnetic saturation changes in the carrier profile by coupling the magnetic fields, which leads to a movement of the magnet group 4, 5.
- a horizontally aligned ferromagnetic carrier profile 1 and a vertically reversed polarity of the permanent magnet pair 4 are arranged such that a stable state of wear of the permanent magnet is achieved, with a support wheel 11 for spacing the permanent magnet from the mounting rail ensures.
- the movement of the permanent magnet 4 is achieved in that a plurality of electromagnets 2, 3 are arranged in parallel on the opposite side of the support magnet 4, that is to say the upper side of the support rail, the two ends of the coil cores being connected to the support profile with a yoke 9 each made of ferromagnetic material .
- a sensor system can detect the respective position of the permanent magnetic load suspension.
- all coil windings can additionally be supplied with a weak alternating current (high frequency). This can also result in a superimposition of the direct current.
- the overall evaluation of all coil currents (measuring and evaluating the magnetic saturation of the individual coil cores) permits precise localization of the permanent magnets.
- the switching of the coil current can also be controlled by suitably positioned, commercially available sensors of various working principles.
- REPLACEMENT BUTT (RULE 26) Prevention of turning / tilting movement when moving off
- a load hangs on at least two carrying heads, that is, on two magnetic levitation / carrying systems (FIG. 16).
- this is prevented by supplying the coil 13 (FIG. 16) lying ahead in the direction of the desired movement with a direct current, the polarity of which exerts a pull 17 on the first permanent magnet group 4 (viewed in the direction of travel).
- This train 17, which arises from the change in the magnetic saturation in the mounting rail 1 and in the core of the coil 13, counteracts the turning / tilting force 16 in such a way that a resulting force or driving vector 18 remains, its Effect in the most positive case shows exactly in the direction of travel.
- the turning / tilting behavior of the load can also be reduced by supplying the coil 14, which is arranged behind the last permanent magnet group in relation to the direction of the desired movement, with a direct current, the polarity of which is at an angle 20 downward in the direction of travel on the last permanent magnet group (seen in the direction of travel).
- the turning / tilting vector 19 is optimally created by the thrust of the coil 14, caused by the change in the magnetic saturation in the mounting rail 1 and in the core of the coil 14, with a suitable design of all components, current strengths and directions of the turning / tilting behavior counteract. In such a case, the thrust vector 21 resulting from 19 and 20 points exactly in the direction of travel (FIG. 16). Lowering
- Automatic door leaves have an air gap of several millimeters compared to the uneven floor surface (currently up to about 7 mm).
- power and hand-operated door leaves, gates and other horizontally movable objects for example at night during the locked state
- This object can be achieved according to the invention in that the coils located precisely over the respective permanent magnet groups are supplied with a stronger direct current pulse than is necessary for moving, which is oriented in such a way that an electromagnetic field opposed to the supporting magnetic field is produced.
- This superimposed field compensates the permanent magnetic field required for carrying so strongly that the holding / floating function is no longer guaranteed and the load (e.g. door leaf) drops to the floor.
- the permanent magnet group with the load is to be raised again to the operating level, this object can be achieved according to the invention in that the coils located exactly above the permanent magnet groups are provided with an opposite current pulse with the effect of building up an electromagnetic field which is the carrying magnetic field strengthened in such a way that the load is raised back to normal holding / floating / operating level.
