Description

MULTI-CAR CYCLIC MAGNETIC ELEVATOR WITH GRAVITY LINEAR ELECTRIC GENERATOR/MOTOR

The present invention relates generally to elevators but more particularly to a scalable multi-car cyclic magnetic elevator cars with gravity linear electric generator including a repulsive magnetic guide assembly to minimizing undesirable movements of the elevator via non-contact magnetic repulsive system. It also uses rotary permanent magnet array magnetic wheel with reinforced gear wheels for attractive magnetic propulsion rather than using an electromagnetic wheel or linear motor propulsion system that is dangerous if used on vertical propulsion because electromagnets are dependent on electricity to attain attractive propulsion, and due to gravity the elevator cars needs to be vertically secured which is what is offered by this present designed magnetic elevator propulsion system with rotary passive magnetic array propulsion wheel. This elevator system is scalable because of the nature this elevator system has to offer, meaning it can accommodate a multiple car system on mono-directional shafts and will deploy or add elevators cars on a need to use basis making this economical elevator system compared to conventional elevator systems.

A conventional traction type elevator includes a cab mounted in a car frame, a counterweight attached to the car frame by a rope or cable, and a drive assembly including a machine driving a traction sheave that engages the rope. As the machine turns the sheave, friction forces between the sheave and the rope move the rope and thereby cause the car frame and counterweight to raise and lower.

A limiting factor in the use of ropes or cable, however, is their durability. As the ropes pass through the sheave they have the tendency to migrate from side to side and contact the sheave rope separators. Contact with the separators increases frictional forces that cause significant abrasion and can degrade the rope materials. Such undesirable migration and resulting friction may also be problematic for flat ropes such as coated steel belts (CSB) that are guided through additional elevator drive components such as rope support roller assemblies attached to the car frame and counterweight.

In some instances, many have thought of guiding the rope at particular locations throughout the elevator drive system to restrain undesirable movement and vibration of the rope. Others have tried to minimize contact between the guide system and rope to further reduce undesirable frictional forces. These, however, have not solved the problem in the use of ropes as above-mentioned.

After a careful study about the existence of these mechanical cable electric elevators, a breakthrough technology was invented where future elevators will no longer need cables or ropes or weight to pull up and down the elevator. Using magnetic levitation and attractive magnetic array propulsion principles, the magnetic elevator was enclosed in a passive magnetic frictionless shaft or guide way and the means of propulsion was using a combination of magnetic array rotary propulsion wheel with gear tooth safety system where the plurality of propulsion motor were attached to the said magnetic array rotary propulsion wheel. The magnetic array rotary propulsion wheel uses a special magnetic array where the North-South-North- South Magnetic field will attract along the length of the magnetic propulsion guide- way using either a Halbach Array, Stetler Array, Alternating Recessed Curve (A.R.C.) or Alternating Recessed Magnetic (A.R.M.) Array where the magnetic field will sum up algebraically following the U shape or Halbach Array vector rotation theorem on both the rotating magnetic wheel attach to the Elevator Car compartment and on the magnetic propulsion guide-way mounted along the length of the elevator shaft.

A physically contacting secondary gear wheel system mounted on the magnetic array rotary propulsion wheel and along the length of the guide-way will give extra safety feature. The air gap is maintained by a roller to maintain a non- contact system between the rotating magnetic field of the magnetic array rotary propulsion wheel and the stationary magnetic array propulsion guide way. This non- contact propulsion system means less maintenance is necessary and wear and tear of the gear tooth wheel is remote. And this time it uses a servo-motor or any types of motors and an attractive magnetic electromagnetic wheel or propulsion system to attain magnetic propulsion that will bring the elevator up and down faster, safer and intelligently using servo motors to control motion. Because the propulsion mechanism is now mounted on the moving elevator compartment, thus eliminate the need for cables or ropes and therefore with this important breakthrough, it is likely that this new magnetic elevator system can adopt a multi-car elevator system.

The advantage of having a multi-car elevator system is that it allows more than one elevator car. or cab that can travel along the length of the cyclic elevator mono-directional shaft. That means that in the future, fewer shafts will be needed to cater multiple cars thus decongesting the traffic flow of the passengers that moves to and pro in the building using at least only two shafts rather than using multiple shaft system. Considering the cost and revenue generating spaces of the elevator shaft which is a possible rentable space real estate wise, the space saving shaft provided by a cyclic multi-car elevator system is a plus factor for the landlords and real estate developers.

Therefore the mono-directional shafts will strictly be used for either upward or downward movement of the traffic in a continuous rotating or cyclic manner. Unlike older multi car system they use cables to move the elevator car, here, with this new invention, having a cable-less system non-contacting magnetic array elevator system means less complicated and more dynamic in terms of changing lanes or shaft direction, etc. A special service bays will be provided along the length of the shaft for troubleshooting of the elevators cars and towards the ends of each loop, a special transition point or terminal or service bay will be provided to change the elevator cars using a mechanical systems either using a robotic arm hydraulic system or electromagnetic lifting system.

What's more, with a magnetic elevator, it is now possible to cater ultra high elevators on a single shaft and the elevators can move extremely fast serving to a pro more traffic in a given time than using a regular cable based elevator system. Especially now a days that the buildings are soaring high at least at more than 110 stories means faster multi-car elevator system is needed to move the people inside the building. A special linear synchronous segmented electromagnetic array or induction motor/generator will be employed for hi-speed magnetic elevator system.

What's more this elevator is equipped with an onboard linear motor/altemator/generator system that can charge the rechargeable battery on board the elevator and the guide way shaft has copper or conductor coils arranged to maximize the axial flux cutting of the field that is directly engaged with a permanent magnetic array on board the elevator such that as soon as the magnetic field is cut through by the copper or conductor coil along the shaft caused by the motion of the elevator either upward or downward by virtue of Faraday's Law of Induction, the copper coil located along the shaft can produce alternating current or direct current that can act as an electric generator to power the whole building or infrastructure converting Kinetic Energy to Electrical Energy. The Mass of the free falling elevator by virtue of gravitational fall will be converted to a valuable and storable energy— ELECTRICITY. Another advantage with this elevator is that since it can produce electricity, the passenger will no longer worry about brownouts and at the same time this elevator is worry free because there is no longer cables that is needed in the whole operation that could easily corrode, wear and tear in time especially in prolonged daily operation.

The primary object of the present invention therefore is to provide a magnetic elevator that uses a combination of passive magnetic array rotary propulsion wheel and gear tooth wheel system to drive elevator cars up and down of a building in a continuous cyclic manner through a mono-directional shaft system having a transition bay in both ends of the elevator shaft.

Further object of this invention is the use of multi-car or multi-cab elevator system thus allowing more traffic flow on a mono-directional shaft with at least one shaft catering the passengers that want to go up, and another shaft that caters passengers that will want to go down, the said elevator shaft is connected by a transition service bay where the elevator cars will change lane or change shaft by means of a special shifting mechanism or lifting mechanism, i.e., hydraulics or electromagnetic robotic arm.

Another object of this invention is the scalable nature this multi car elevator system is. All the building developer or Architects needs to do is to develop only at least two elevator shafts and there is no need to develop more shafts because of the scalable nature this multi-car cyclic magnetic elevator system is. AU they need to do is to add additional elevator cars on a need to have or addλasis, say assuming the number of traffic has increased, and thus require additional cars. This is beneficial to the real estate developer because they not only save the rentable space of the elevator shaft, but they can add additional elevators cars as traffic increase. This system can be adopted to existing conventional elevator system.

Also another object of this invention is the invention of service bays intermittently located along the length of the elevator shaft. These service bays will cater defective elevator car thus allowing the continuous flow of traffic of other elevators. A special gear system is mounted on the gearbox assembly of the magnetic array rotary wheel so that the elevator cars will only move strictly on one direction for safety considerations.

Another object of this invention is a magnetic elevator having a gravity linear electric generator having a plurality of magnetic array propelling system that suspends the elevator car in midair and driving said elevator car up and down the elevator shaft.

Still an object of this invention for a magnetic elevator having a gravity linear electric generator that generates electricity to supply electric requirement of the propulsion motor thereof to run the magnetic array propelling system. Another object of this invention is the life-saving feature this elevator will offer in cases of emergency. When engaged to emergency mode, the elevator will shut down areas affected by natural and man made catastrophe such as fire or earthquake. Thus when the elevator is on an emergency mode, it will deploy the passenger from the unaffected floors to come down as fast as possible to bring people down on a much faster mode. Since there is no more cable to cut along the entire length of the elevator shaft thus safeguarding the people from man made or natural catastrophe. On the event that a fire or an airplane will struck at a certain floor of the building, event on this uneventful catastrophe, the magnetic elevator will continue to bring to a pro of people or goods to safety. A special locking mechanism will be provided on every floor to protect the magnetic elevator guide way from debris. These and other objects and advantages will come to view and be understood upon a reading of the detailed description when taken in conjunction with the appended drawings:

(A.R.C.) Array showing the recessed arrangement of circular magnetic array; Figure 8D is the isometric view of the passive Stetler Magnetic Array; Referring now to the several views of the drawing in detail, there is shown a magnetic elevator herewith can also be referred as a multi-car cyclic magnetic elevator system with gravity linear electric generator generally designated as reference numeral 1. Figure 1 shows the elevation view of the cyclic multi-car magnetic elevator system 1 disposed along the length of a building with a plurality of cyclic multi-car magnetic elevator car 10 which is disposed in every location shown along the entire length of the parallel upward mono-directional shaft 2 that goes strictly upwards and an another downward mono-directional shaft 4 that strictly goes downwards. The cyclic multi-car magnetic elevator car 10 will run along the length of both mono-directional shafts 2 and 4 via a linear magnetic array guide way 7 by virtue of the rotating magnetic array rotary wheel 8. To complete the cyclic pattern of this cyclic multi-car magnetic elevator system 1, an upper end transition bay 3 and lower end transition bay 5 is provided both to function as a transition area or service area or terminal to store as many multi-car elevator cars 10 as possible. On the upper end transition bay 3 has a upper bay mechanical electromagnetic arm 3 a will attract the cyclic multi-car magnetic elevator car 10 and move it anywhere in the upper end transition bay 3 or to the upper end terminal bay 3 e or to the downward mono- directional shaft 4 to continue the rotation of elevator service. The upper bay mechanical electromagnetic arm 3 a is attached to a mechanical or hydraulic conveyor system 3b driven by a motor 3c and a gear box 3d. Once the upper bay mechanical electromagnetic arm 3 a will lock and secure the cyclic multi-car magnetic elevator car 10 to the downward mono-directional shaft 4, it will continue its elevator service down to the lower end transition bay 5 where the lower bay mechanical electromagnetic arm 5 a will attract the cyclic multi-car magnetic elevator car 10 and move it anywhere in the lower end transition bay 5 or at the lower end terminal bay 5c for service, repair, storage or move it back to the upward mono-directional shaft 2 to complete the magnetic elevator cyclic pattern. This is attained using a hydraulic or mechanical arm system 5b that pulls the lower bay mechanical electromagnetic arm 5 a forward or backward.

The advantage with this cyclic multi-car elevator system is the scalable nature this multi car elevator system is. All the building developer or Architects needs to do is to develop only at least two elevator shafts (upward or downward shaft) and there is no need to develop more shafts because of the scalable nature this multi-car cyclic magnetic elevator system is. All they need to do is to add additional elevator cars on a need to have or add basis, say assuming the number of traffic has increased, and thus require additional cars.

A computer control navigation system 9 that controls the orderly flow of the cyclic multi-car magnetic elevator system 1, if it detects some defects or warning signal triggered by some sensors (not shown) located on the cyclic multi-car magnetic elevator car 10, one of the middle service bay 6 will be opened to facilitate the defective cyclic multi-car magnetic elevator car 10 for immediate repair. This middle service bay 6 will help facilitate the continuous non stop flow of traffic of elevators within the building especially if one of the cyclic multi-car magnetic elevator car 10 is experiencing technical problems in the middle of the building. An elevator door 17 is mounted on every cyclic multi-car magnetic elevator car 10. Figure 2, 3, 3A, 3C, 4 and 5 are the perspective view, side view, sectional, isometric and top view respectively of the preferred embodiment for a magnetic elevator with gravity linear electric generator according to the present invention having a plurality of rotary magnetic array propulsion wheel 8 where the said propulsion wheels are attached with a magnetic array propulsion rotor 8b arranged in a North-South-North-South Alternating Recessed Curve (A.R.C.) Array or Halbach Array, Stelter Array using permanent magnets such as Neodymium Iron Boron or other Rare Earth Magnets or magnets having stronger attractive force. The said magnetic array propulsion rotor 8b is enclosed by a plurality of propulsion gear wheels 8a that is connected to an axle 13a that is driven by a motor 12 attached to a gear box 13.

The propulsion gear wheels 8a will act as a back up in case the magnetic array propulsion rotor 8b is not sufficient enough to carry the load or will act as a secondary physically contacting gear propulsion system. The said magnetic array propulsion wheel 8 will be in non contact engagement with linear magnetic array guide way 7 that will act as a stator. The said linear magnetic array guide way 7 is composed with a linear magnetic array stator 7a which is made of permanent magnets ideally Neodymium Iron Boron or other Rare Earth Magnets or having stronger attractive force arranged in an North-South-North-South Alternating Recessed Magnetic (A.R.M.) Array or Halbach Array, Stelter Array. A linear gear guide way 7b will sandwich the linear magnetic array stator 7a that is mounted on a linear guide way holder 7c. A roller 8c will maintain the necessary air gap so that the rotary magnetic array propulsion wheel 8 will attain the non-contact attractive magnetic propulsion with respect to the linear magnetic array guide way 7. A non contact magnetic levitation is attained when the cyclic multi-car magnetic elevator car 10 is mounted with the plurality of magnetic array levitator 11a arranged in a mono-polar Alternating Recessed Magnetic (A.R.M.) Array, monopolar Halbach Array, U-shaped Array, mono-polar Stetler array that is in repulsive non contact engagement with the intermittently spaced apart magnetic array levitation guide way l ib arranged in a mono-polar Alternating Recessed Magnetic (A.R.M.) Array, mono-polar Halbach Array, U-shaped Array, mono-polar Stetler array that is mounted along the entire length of the mono-directional shaft 2 and 4. A roller stabilizer l ie will help the non-contact magnetic levitation.

However if cost is prohibitive for the magnetic levitation guide way configuration, a simple traditional roller guide will be used instead of the magnetic levitation guide way system. In Figure 3B shows the conventional roller guide system where the plurality of conventional roller stabilizer l ie connected to a roller holder l ie will be securely engaged in a physically contacting conventional guide that will follow the length of the conventional rail guide way 1 If located at least in two sides of the mono-directional elevator shaft (not shown). The said multi-car cyclic elevator system with gravity linear electric generator

1 is designed to generate electricity my converting kinetic energy to electricity by virtue of the falling mass which is the elevator and its load. This will help recover the energy by using gravity to produce electricity using the Faraday Law of Induction. An axial flux cutting using linear segmented electromagnetic array will be used to produce maximum electricity through LORENZ FORCE LAW. A reverse can be attained if the stator, instead of producing electricity can be converted to a high torque motor by supplying electricity to the linear segmented electromagnetic array stator coils. It can be said that a motor can be a generator or a linear motor can be a linear generator and vice versa. And if we apply the principle of LENZ LAW the same mechanism and design can be used to attain non contact levitation or attain magnetic braking that will be activated in cases of emergency or emergency braking system. In Figure 6, 6A shows the segmented electromagnetic array linear gravity generator/motor/levitator/brake having copper conductor stator 15 wounded in a plastic bobbins iron-less core 15a arranged in an axial flux cutting to maximize the electric generation and or high torque motor. A magnetic array linear rotor 14 is arranged in a Halbach Array, Stetler Array or Alternating Recessed Magnetic (A.R.M.) Array using strong permanent magnets such as Neodymium Iron Boron or other Rare Earth Magnets such as Samarium Cobalt Nickel or Aluminum Nickel Cobalt. Electricity can be stored on board the elevator battery pack 16 or in a central power storage UPS system located within the building (not shown). However this linear generator system can also be used as a linear motor, where instead of generating electricity, the segmented electromagnetic array linear gravity generator having copper conductor stator 15 will be supplied with electricity controlled by an electronic system (not shown) that will drive the alternating North-South-North-South magnetic array linear rotor 14 is arranged in a Halbach Array to move upward or downward depending on the polarity of the electricity supplies to the copper conductor stator 15.

Figure 7 is another embodiment of the magnetic propulsion system, ideal for industrial or heavy loads. A magnetic propulsion track 18 having a magnetic array traction foot 18a mounted to steel belts 18b that is rotated by the sprocket 18c to attain attractive magnetic propulsion. A motor 12 is connected by an axle 19 that will drive one of the sprockets located at the magnetic propulsion track 18. A symmetrical magnetic propulsion track 20 can be mounted on any side of the elevator body to increase performance and carrying capacity.

Figure 8 is a Halbach Array configuration showing the true south magnetic pole 21a and true north magnetic pole 21b where a lateral magnet 21c is arranged in such a way that flux lines will follow the vector rotation theorem of Halbach Array or U-shape magnet represented by a dotted flux line 21 d.

Array configuration showing the true south magnetic pole 21a and true north magnetic pole 21b where a lateral magnet 21c is arranged in such a way that flux lines will follow the vector rotation theorem of Halbach Array or U-shape magnet represented by a dotted flux line 2 Id. A slightly recessed arrangement was attained where the (X) 21 e is => 1- 99% recessed away from the base to increase the magnetic flux density increasing the magnetic field strength of the array than the Halbach Array. This magnetic array is ideal for concentrated attractive magnetic purposes like linear magnetic guide way where the flux density is concentrated on one side of the array, and cancels on the other side of the array according to Halbach Array vector rotation theorem thus increase the attractive engagements of permanent magnets thus increase also it load carrying capacity.

Figure 8C is an Alternating Recessed Curve (A.R.C.) Array configuration showing the true south magnetic pole 21a and true north magnetic pole 21b where a lateral magnet 21c is arranged in such a way that flux lines will follow the vector rotation theorem of Halbach Array or U-shape magnet represented by a dotted flux line 2 Id. A slightly recessed arrangement was attained where the (X) 21 e is => 1- 99% recessed away from the base to increase the magnetic flux density increasing the magnetic field strength of the array than the Halbach Array. This magnetic array is ideal for concentrated attractive magnetic purposes like rotary magnetic array wheel where the flux density is concentrated on one side of the array, and cancels on the other side of the array according to Halbach Array vector rotation theorem thus increase the attractive engagements of permanent magnets thus increase also it load carrying capacity and magnetic traction on the linear magnetic array guide way. Figure 8D is a Stetler Array configuration of passive magnetic array where the strength of all magnetic fields will sum up algebraically thus increase the repulsive or attractive performance of a passive magnetic array. The true south magnetic pole 21a or the true north magnetic pole 21b is sandwiched from all its sides by lateral magnet 21c to increase the strength of either the true north magnetic pole 21b or true south magnetic pole 21a. The settler array can be configures to become mono-polar or bipolar depending on the use or application of the said magnet either for propulsion or for levitation. It can be used on the linear propulsion guide way, rotary propulsion magnetic array wheel or mono-polar magnetic levitation purposes.
