Definitions
- a combined support, drive and power ⁇ transmission device for a magnetic levitation vehicle be ⁇ known.
- This device has a threaded along a roadway long stator, which is equipped with a magnet core having a plurality of successive track in the longitudinal direction ssen ⁇ parallel grooves which run transversely to the longitudinal track direction ⁇ ; in the grooves, a 3-phase alternating ⁇ current winding is inserted. Due to its length, the long stator can not be produced in one piece with regard to the magnetic core and the alternating-current winding, but rather consists of individual magnetic blocks which are arranged abutting one behind the other along the travel path.
- the long stator is associated with a support magnet of a magnetic levitation railway vehicle, which is to be moved along the travel path formed by the long stator.
- the supporting magnet is also composed of individual netblöcken Mag ⁇ , the terminal posts with grooves for ⁇
- a linear generator which serves for the energy supply of the magnetic levitation vehicle on domestic duktivem ways.
- the invention has for its object to further reduce ripple forces.
- a magnetic ⁇ block for a magnetic levitation system having a first Mag ⁇ netblöcke having long stator and a netblöcken from second Mag ⁇ composite supporting magnet having a plurality of paral ⁇ Lelen grooves in pole heads for receiving windings of a linear generator, each first magnet block having a plurality of pa ⁇ rallele grooves extending transversely to the longitudinal direction of each ers ⁇ th magnet block by one slot pitch oblique, and wherein the grooves extend to the grooves in the first magnet blocks accordingly in the polar heads with a bevel entspre ⁇ .
- the invention is namely based on the knowledge that additional Ripple theory result from edge effects of the magneti ⁇ rule fields and also characterized in that the point of attack of the Kraftan ⁇ emanating from a pole head sum force egg ne changing position in the direction of travel has.
- This sharmlichen to ⁇ Ripple guide are considerably reduced by the inventively ⁇ provided oblique course of the grooves in the magnet blocks of the long stator, and by a entspre ⁇ sponding slope of the grooves in the linear generator an impairment of the power supply of the magnetic levitation vehicle is prevented. According to the invention, therefore, the ripple forces of the individual pole heads themselves are reduced.
- a further solution to the above-mentioned object is a magnetic block for a magnetic levitation system having a first magnet stator long stator and a second magnet blocks composed of supporting magnet with multiple parallel grooves in Polkmün for receiving Wicklun ⁇ conditions of a linear generator, each pole head between the parallel grooves each having an intermediate tooth and extending along the outer grooves outdoor areas, according to the invention is that the outer regions changed each pole piece in the direction of the grooves in the width such verän ⁇ and are designed complementary to the Bacbrei ⁇ te of the two outer regions along the grooves always corresponds to the width of a tooth.
- Magnet ⁇ blocks An essential advantage of this invention Magnet ⁇ blocks is that it can be used to produce a magnetic levitation system with long stator and supporting magnet, in which the additional Ripple protector are largely reduced. This is achieved with advantageously little effort alone by changing the width of the outer region of the pole heads of the supporting magnet; the long stator and the linear generator can remain unchanged compared to known design.
- the outer regions of the pole heads can be varied in their width in different ways. It is important that the width of the outer areas is not constant, as is the case in the prior art. Thus, for example, the width of the outer regions per ⁇ of the pole head in the direction of the grooves can be changed sinusoidally complementary.
- the invention further relates to a method for producing a method for producing a magnet block for a magnet made of magnet blocks supporting magnet of a maglev system having a plurality of parallel grooves in Polkmün for receiving windings of a Lineargenera- sector, each pole head between the parallel grooves each having an intervening tooth and outer regions extending along the outer grooves, and according to the invention provides that the outer widths of each pole head, which are so varied and complementarily shaped in width, that the total width of the two outer regions along the Grooves always corresponds to the width of a tooth, sheets with outer areas each egg ⁇ ner corresponding to a tooth width in the Polkopf Symposium be pre-punched and then each successively with a for the outer areas only the width of a single tooth beschreib be punched visually punching tool, wherein the formation of the magnetic block successive sheets are stamped with each lateral offset.
- This method is advantageous above all in that since ⁇ with a relatively complicated shaped magnet block for supporting magnets of a magnetic levitation system made of sheet metal with simple punching tools in two punching steps relatively ein ⁇ way can be produced.
- Figure 1 is a perspective view of a pole head of an embodiment of the magnetic block according to the invention for a support magnet and in
- Figure 2 reproduced the processing of a sheet for producing such a pole head.
- a pole piece 1 of a magnetic block, not shown, of a supporting magnet in the region of its pole head 2 is provided with grooves 3, 4, 5 and 6, between which teeth 7 lie with a width a.
- These grooves 3 to 6 lie in the Y direction of the coordinate system likewise shown in FIG. 1 and thus transversely to the X direction, which indicates the travel direction of a magnetic levitation train equipped with the illustrated elements or the longitudinal direction of the carrying magnet.
- a leg 8 connects to the bottom, around which a Gleichstrom ⁇ winding is set as a field winding in the fully assembled state ge.
- the pole head 2 is in the extending along the grooves 3 to 6 outer region 9 or
- the sheet 20 in this case has a width B in the region 21 which is greater by a total of the width a of a toothed part 24 than is required for pole pieces of known supporting magnets; This width results from the fact that the outer part 23 as well as another outer part 25 by half the width a of the tooth part 24 is larger.
- the sheet 20 is, after the first sheet section and Stanz ⁇ step by means of a second cutting die 26 punches nachge ⁇ containing 20 gives the sheet the final width in the range 21 to form the pole piece.
- the different Konfigu ⁇ ration of the individual sheets 20 in the area 21 and thus a slope in the outer region 9 and 10 of the pole head 2 (see Fig. 1) is achieved in that the forming the pole 1 sheets 20 for punching successively laterally are moved, wherein the sheet 20 is displaced by a vorge given step relative to the cutting position of the tool 26.
- a metal sheet 20 is formed by the re-punching process, which forms the pole head with an ⁇ sch manendem leg approximately half the length of the grooves 3 to 6.
- a piece of sheet metal 20 is in a position bezüg ⁇ Lich the position of the cutting tool 23 in which the right edge 27 is located the cutting tool 26 above the position 28, the result is a plate 20, as at the ends of the grooves 3 and 6 using Can be found.
