Description

S P E C I F I C A T I O N MAGNETIC LEVITATION TRANSPORT SYSTEM
FIELD OF INVENTION The present invention relates generally to magnetic levitation transport system but more particularly to a magnetic levitation vehicle that levitates using a spin stabilized magnetic disc assembly using permanent magnets arranged in an electromagnetic array or in a U or C shaped array, in an intermittent arrangement, and a dynamic magnetic suspension stabilizer that will attain stable and economical magnetic levitation using permanent magnets that allowed to spin freely combined with a linear solenoid assembly that will act as a secondary repulsive levitation system and linear electric generator at the same time. BACKGROUND OF THE INVENTION The concept of a magnetic levitation vehicle has been around for more than 60 years now. This was a brainchild of a German Scientist Hermann Kemper. On August 14, 1934, he received a patent for the magnetic levitation of vehicles in Germany.
In the mid 1900s, Britain became the first country to introduce a magnetic levitation service. It was to link two terminals at Birmingham airport about 400 meters long and a top speed of about 10-mph. However it was recently replaced with a bus service due to difficulty of getting spare parts.
Since then, there has been a lot of research and experiments for Magnetic Levitation Vehicles in countries like Germany, Japan or USA. The German TRANSAPID Electro Magnetic System (EMS) is now successfully operational for commercial use in China that connects the Podung Airport to Shanghai metropolis. The journey time will be no more than 60 minutes for the 292-km giving rise to an impressive 292kph average speed. In Japan, after fundamental tests in the laboratory to verify the feasibility of high-speed running at 500 kph, the construction work of a 7-km test track began in Japan's Miyazaki Prefecture in 1975. The manned two- car vehicle registered a speed of 400.8 kph in 1987. In 1997, the project in a three-car vehicle set achieved world speed records, attaining a maximum speed of 531 kph in a manned vehicle run on December 12 and a maximum speed of 550 kph in an unmanned vehicle on December 24. On April 14, 1999, a five-car vehicle set surpassed the speed record, attaining a maximum speed of 552 kph in a manned vehicle run. The principle of a magnetic vehicle is that it floats on a magnetic field using electromagnetic principle, superconductivity, Halbach Array (invented by Klaus Halbach) permanent magnets and electromagnetic array and is propelled by a linear synchronous, induction motor or dynamic electromagnetic wheel. They follow guidance tracks with magnets. These vehicles are often referred to as Magnetically Levitated, which is abbreviated, to Maglev.
Maglev is a system in which the vehicle runs levitated from the guide way (corresponding to the rail tracks of conventional railways) by using electromagnetic forces, super conducting magnets, Halbach Array permanent magnets or Electromagnetic Array on board the vehicle and coils on the ground. A maglev vehicle levitates about 10mm or more above the guide way on a magnetic flux cushion depending on the levitation principle used on the maglev system. It is propelled by the guide way itself rather than an onboard engine by changing magnetic fields. Once the vehicle is pulled into the next section the magnetism switches so that the vehicle is pulled on again. The Electro-magnets run the length of the guide way.
The primary advantage of a magnetic levitated vehicle is maintenance. Because the vehicle floats along a frictionless magnetic guideway, there is no contact with the ground and therefore no need for any moving parts. As a result there are no components that would wear out. This means that vehicles and tracks would need no maintenance at all. The second advantage is that because maglev vehicles float; there is no friction and noise. And finally, the speed as a result it is more viable for said maglev vehicle to travel extremely fast, i.e. about 500kph or more depending on the environment it is cruising, say if the vehicle travels along the vacuum, therefore it can attain up 800kph or more because there is no wind resistance acting against its body.
However, there are several disadvantages with maglev vehicles. Maglev guide paths are bound to be more costly than conventional steel railways. Most existing maglev system requires a continuous magnetic, electromagnetic and superconducting plate that runs the length of the guideway. This means it is costly to build just the guideway system. The other disadvantage is lack of existing infrastructure. For example, if a highspeed line between two cities is built, then high-speed maglev vehicles can only serve both cities but would not be able to serve other lines or normal railways branching out therefrom which require normal speed. This means that maglev vehicles are strictly limited only to high-speed lines and not flexible enough to serve other lines.
Although the Maglev technology has been around for quite some time now, however its application was concentrated on the use of mass transportation and the cost to build it is very expensive especially using superconductivity or electromagnetic principles of levitation.
Currently there are three Major Categories of Maglev System, the EDS, the EMS and the Inductrak. These are some of the draw backs of these existing Maglev Systems now already in commercial application, on the test line and on the laboratory: EDS: Electro Dynamic System Japanese Superconducting Maglev
1. It is based on the principle of superconductivity to attain magnetic levitation. Therefore, it is needed to have a frigid temperature to attain magnetic levitation. In Japan they are using cryogenic or refrigeration system with Nitrogen and Helium on board the vehicle and on the track or maglev guideway to attain superconductivity making the vehicle heavier and with complicated sub-systems;
2. Since the system requires superconducting, the passengers must be shielded so they will not be exposed to a high magnetic field. As a result, electromagnetic field EMF insulation system would be needed for protection.
3. Although the levitation is higher at about 8 inches because of superconductivity, the need to maintain the right temperature is crucial. Absence of this factor, would affect the levitation performance. As a result, this system becomes applicable only in cold countries like Japan or the Northern Hemisphere and cannot be used in tropical or warm countries. Building one like this in warm countries would only mean higher operational and maintenance cost. 4. With this system, the levitation and propulsion system is integrated, making it very difficult to assess and trouble shoot where a system fails.
5. Needs auxiliary wheels during initial propulsion and landing.
6. The guideway is bulky and massive and very complicated to build or maintain and needs refrigeration system making it expensive.
7. Because of the guideway design it is difficult for the vehicle to make sharp curves and U turn.
8. The propulsion and levitation uses the same guideway system. EMS: Electro Magnetic System German Transrapid Electromagnetic Maglev
1. It is based on the principle of electromagnetism to attain attractive magnetic levitation. Therefore, it is needed to have an on board battery pack or power system to attain and maintain levitation and propulsion. With out power, the vehicle will not levitate, and if there is power failure while the vehicle is running at high speed, this might end to a possible fatal and dangerous magnetic levitation crash. 2. As a result, the system is likewise expensive as there is a need to maintain additional operational cost on power system for its levitation. In fact, there is a need to constantly monitor the air gap between the vehicle and the guideway. Monitoring is done using sensors and transmission antenna to the control station to make sure that everything is on the right track. Failure of one of these systems can be dangerous.
3. There's a lot of subsystem needed to monitor the Levitation and Propulsion System and the levitation is a very low 10mm. Sometimes during propulsion the gap between the guideway and the electromagnetic propulsion and levitation device is at a critical 1mm gap of clearance. Any wind or natural disturbances may cause fatal contact to the guideway.
4. For propulsion it uses the linear synchronous motor. 5. The guideway is simplified but needs electricity which is distributed precisely where the vehicle is located again, a system that requires a lot of electronic and navigational controls and power. 6. With this system, the levitation and propulsion system is integrated in one location. These means that it will be difficult to assess and trouble shoot where a system failed.
. 7. It needs constant electricity supply to operate the propulsion and the levitation systems, rendering it necessary to have a battery power system on board, making the vehicle much heavier. EMS: Electro Magnetic System American Version American lnductrack Maglev
1. The system is based on the principle of electromagnetism to attain repulsive magnetic levitation. The levitation is attained during propulsion at a certain speed as a result of induced electricity produced by the short-circuited coils and the Halbach array permanent magnets. 2. As a result the system is less expensive than the previously mentioned two maglev systems (the EDS and EMS)..
3. Like the two other systems, the levitation and propulsion systems are integrated making it difficult to conduct trouble shooting on defective systems.
4. It uses a linear induction motor for propulsion.
5. Needs auxiliary wheels during initial propulsion and landing.
After a careful and thorough research and conceptualization of the Principle of other Magnetic Levitation System, a break through technology has been adapted wherein this new generation of maglev system will answer the major draw backs of existing maglev systems developed in countries like Germany, Japan and USA. This new Dynamic Maglev System will certainly transform the way people move in the future because it uses only permanent magnets that are made to spin freely to attain stable magnetic levitation that will make the levitation system cheaper than superconductivity system or electromagnetic systems develop in Japan and Germany respectively. At the same time we use the same moving magnetic field on the vehicle to generate electricity if it is engaged on a solenoid linear guideway system. This added functionality of a maglev system is an important breakthrough in urban or countryside electric power generation because this time the magnetic guideway becomes an electric generating device that may power the lights and operation of the maglev system and perhaps power a suburb or a city. This will also compensate in time the cost of building this exorbitant maglev guideway system because of the potential revenue the maglev operator may gain in this unorthodox means to generate renewable and sustainable artificial alternative electricity generator. This system will seamlessly be integrate in the urban or countryside for their source of free electricity in the future at the same time as a means of cheap and efficient mass transportation. The primary object of this invention therefore is to provide a Magnetic Levitated transport system that solves the drawbacks inherent to the existing Maglev vehicle systems.
Another object of this invention is to provide a magnetic levitation transport system using a Segmented Electromagnetic Array (SEMA) synchronous motor or servo motor in one roof for high speed propulsion or low speed digital propulsion.
Another object of this invention is to provide a Magnetic Levitated vehicle that runs on a linear magnetic generator, using intermittent spaced apart spinning permanent magnetic disc in a Halbach Array, U or C shaped array or Electromagnetic Array configuration.
Still an object of this invention is to provide a magnetic levitation transport system that is environment friendly since no air pollutants that comes off the vehicle nor noise that is being produced thereof because it uses an on-board battery recharged continuously using the on-board linear alternator or can be powered by hydrogen fuel-cell or hydro-fuel-cell system using on-board water electrolysis and fuel-cell energy generator ecosystem or can be powered from an external power supply.
Another object of this invention is to provide a magnetic levitation transport system having the ability to produce electricity as the moving vehicle body is engaged in the linear solenoid coil assembly located along the guideway that will act as a linear electric generator apparatus and at the same time a secondary levitation guidance device. The electric output can be stored to re-chargeable back-up or standby batteries, or other applications as deemed necessary.
Yet, an object of this invention is to provide a magnetic levitation transport system having a polarity similar to the polarity of the magnetic guideway using permanent magnets in a spinning Circular Halbach Array, Circular U or C shaped array or Circular Electromagnetic Array, that when engaged, the vehicle attains stable repulsive magnetic levitation or suspended in mid-air on a magnetic flux cushion. The spinning of both the guideway and the magnetic suspension stabilizer on the vehicle's body will make the levitation stable using rare earth permanent magnets in a circular Halbach Array or any Magnetic Array configuration.

Said magnet array could also be of U-shape permanent magnet being
5 wound by copper wires. Said magnetic disc 18 is rotatably enclosed by an electromagnetic bearing 20 or any other type of bearing that serves the purpose. Each passive magnetic disc assembly 16 is supported in a concrete or reinforced plastic housing 21 inclinedly secured to said concrete support 13.
10. Said linear guideway electric generators 17 are stationary located between the spaced apart passive magnetic discs assemblies 16 along said magnetic levitation guideway 12 and are respectively made of an iron core (not shown) and copper coils 22 wound around said iron core.
The ferromagnetic attractive propulsion guideway 14 which is laid
15 out in between said pair of parallel vehicle levitation guideways 15 on said concrete support 13 is basically a continuous I-beam 23 mounted with a metal sheet 24 mounted thereon.
The magnetic levitation vehicle 11 includes a conventional vehicle body 25 being provided with an inclined magnetic suspension stabilizer 26
20 at the lower opposing sides of said train body 25 and in communication with the respectively parallel vehicle levitation guideways 15. Said magnetic suspension stabilizer 26 is being defined by a plurality of magnetic array spinning discs 27 spacedly disposed in a linear pattern thereof. Said magnetic array spinning discs 27 react with said passive magnetic discs
25 assemblies 16 of said vehicle levitation guideways 15 in a repulsive behavior resulting to the levitation of said vehicle body 25. Each of said magnetic array spinning discs 27 is arranged in a circular magnet array such as Halbach array, electromagnetic array. Said magnet array could also be of U-shape permanent magnet being wound by copper wires. The
30 magnetic array spinning discs 27 are respectively coupled with a pinion and gear combination 28 and 29 that are securedly mounted on a common axle 30 which in turn is drivenly coupled to a motor 31. Said motor 31 causes the rotation of said magnetic array spinning discs 27 at a predetermined speed. As shown in Figures 2 and 3, the pinions 28 of the adjacent magnetic array spinning discs 27 are opposedly oriented so that each magnetic array spinning discs 27 would rotate in a different direction with respect to the adjacent magnetic array spinning discs. This counter rotation is necessary to prevent the sideward movement effect of the vehicle body 25 being brought by the rotation of the spinning discs 27.
The degree of inclination of the magnetic suspension stabilizer 26 is similar to the inclination of the magnetic discs 18 of the passive magnetic levitation guideway 12. The magnetic discs 18 would rotate dynamically when engaged with a passing maglev vehicle magnetic suspension stabilizer 26 due to the forces of repulsive and attractive magnetic force of engaged Halbach Array spinning disc, frictionless torque and gravity. This is the primary passive magnetic suspension levitation that will allow the maglev vehicle to suspend in a frictionless magnetic space with or without the use of electricity. The magnetic array spinning discs 27 makes the levitation higher or stronger depending on the load or use of the vehicle. This can be so if the magnetic array spinning discs 27 is charged with high voltage of electric current. The stronger the current the higher the levitation and vice versa.
At the same time the sloping design of the passive magnetic levitation guideway 12 makes the vehicle slide towards the center of gravity providing balance and stability of magnetic levitation as shown in the drawings. This alternating or intermittent levitation guideway system will cut up to 50-70% of the required permanent magnets on the guideway using the conventional levitation technique. This means that the cost on building the magnetic guideway will be reduced.
Moreover, the linear guideway electric generators would generate electricity as the magnetic array spinning discs 27 of said inclined magnetic suspension stabilizer 26 passes over. Since said linear guideway electric generators said is made of an iron core and a copper coils wound around the core, said linear guideway electric generators becomes a dynamic electric generating device and transmission line at the same time, where the electric output will be stored or recharged on a replacement battery, transformer, or electrolyze water in a water electrolysis device located strategically in every Maglev vehicle station, or used to light the guideway system, vehicle station or other electric or power needs like power the elevator or escalator and so on.
Along the line of the magnetic array spinning discs 27 is an on-board electric generator 32 being constructed similarly with said linear guideway electric generators 17 and generates electricity when passed through said passive magnetic discs assemblies 16. Said on-board generator 32 acts as an alternator to charge the on-board battery pack 33 provided on said vehicle body 25. In between said magnetic suspension stabilizers 26 and at the lower portion of said vehicle body 11 is a plurality of spaced apart pairs of magnetic propulsion wheel assemblies 34. Said pair of magnetic propulsion wheel assemblies 34 are basically disposed linearly at the middle bottom portion of said vehicle body 25. Said magnetic propulsion wheel assemblies 34 are responsible for the forward and backward movement of said vehicle body 25. Each of said magnetic propulsion wheel assemblies 34 consists of a conical wheel 35 defined by a conical housing 36 confining a conically shaped plurality of electromagnets 37, each being defined by a U-shaped magnetic array 47 wound with copper wire 48 rotatably communicating with a commutator (not shown) provided therewith. Said U-shaped magnetic array 47 are supplied by electric power from an on-board battery pack 33. Said electromagnets 37 are held together at the center thereof that is rotatably connected to a servo or synchronous motor 38 secured thereat. As best seen in Figure 5 and 6, said conical wheel 35 is disposed angularly such that a portion of the surface thereof is held horizontally at the lowest portion of said magnetic propulsion wheel assembly 34. The electromagnets 37 at this horizontal surface portion 38 are held very near the surface of the ferromagnetic attractive propulsion guideway 14. Hence, once the conical wheels 35 start to rotate in the forward direction, the electromagnets 37 would attract the metal sheet 24 of said ferromagnetic attractive propulsion guideway 14 causing the entire vehicle body 25 to move forward while in levitation due to the repulsive force present between the magnetic suspension stabilizer 26 and the magnetic levitation guideway 12. Furthermore, as shown, the engagement area of the horizontal surface portion 38 of the pair of conical wheels 35 covers only the entire width of the metal sheet 24. This means therefore that disengagement of the conical wheels 35 from said metal sheet 24 can be attained if the said conical wheels 35 are rotated so that the horizontal surface portion 39 would be outside said metal sheet 24. Such situation is ideal when said vehicle body 25 reaches a desired speed whereby it's momentum would just be the one propelling said vehicle body 25.
To disengaged said conical wheels 35 with the ferromagnetic attractive propulsion guideway 14, each of said magnetic propulsion wheel assemblies 34 is provided with a cylindrical casing 40 wherein said conical wheel 35 and motor 38 are securedly disposed. The base 41 of said cylindrical casing 40 is provided with an annular gear 42 that is engageably provided with a pinion 43 and an electric motor 44 coupled therefore. The motor 44 drives the pinion 43 and rotate said cylindrical casing 40 by 180°. This will also rotate the conical wheel 35 by 180° thereby disengaging the electromagnets 37 with the metal sheet 24 of said ferromagnetic attractive propulsion guideway 14.
Another feature of the present invention is in the provision of rubberized landing gears 45 that are spacedly disposed below the vehicle body 25. Said rubberized landing gears 45 supports said vehicle body 25 specially during loading of passengers in a loading station. This will also protect the levitation mechanisms such as the magnetic suspension stabilizer 26 and magnetic propulsion wheel assemblies from damage, Side bumpers 46 are also provided at the sides of said vehicle body 25 to protect the sides of the vehicle body 25 from getting in contact with the guideways railing during curve turns and the like.
Figure 8 shows another embodiment of the vehicle body 25' wherein the ferromagnetic attractive propulsion guideway 14' and the associated magnetic suspension stabilizers 26' are disposed in a horizontal manner.
