Description

BACKGROUND OF THE INVENTION

The generator of the present invention is based upon the same laws of electromagnetism utilised in conventional generators, butts different in its configuration and mode of operation. Most prior generators are characterised by relative mofion between a coil of wire and a magnetic field such that the wire cuts through the lines of force of the magnetic field to generate electricity in the coiL This requires electrical windings on a rotor, the use of sUp rings or brushes to accommodate the rotation of the windings and the maintenance of a rotating electrical connection. Some of the problems associated with such a design. include the continuous attention required by slip rings or brushes and the serious operational hazards arising from the continuous arcing and sparking as the rotor contacts move past the stationary brush. Slip rings and brushes also degrade operational efficiency through electric power loss from the electrical resistance of the brush contact and through mechanical friction oss from the drag oIthe brushes on the rotor. The presence of windings on the rotor also significantly increases the weight or mass of the rotor, necessitating slower rotational speeds and more energy from the prime mover. Still further, th.e constant rotation an.d heating of the coils causes them to fatigue and fail with time.

Some prior generators function without slip rings and brushes, but have other inherent limitations not found in the more common generator designs. For example, the inductor alternator varies magnetic path induction by means of a wireless toothed rotor. The field is maintained by electromagnets on the stator and the armature coils are also mounted on the stator. The inductor alternator has not found widespread acceptance since it is more bulky and less efficient than more traditional generator types.

Further aspects oIprior generators which detract from performance include full reversal of the magnetic field, resulting in hysteresis loss, eddy current loss and heat production; and Lenz's reaction and harmonics which reduce output quality and efficiency.

The present invention incorporates virtually aU of the positive characteristics of all previous generator types including but not limited to those discussed herein. Further, it eliminates or mitigates many of the problems associated with such generator designs.

The present invention utilises stationary permanent magnets, stationary armature windings and a rotor with no windings. Motion of the rotor acts as a magnetic switch and varies the reluctance of a magnetic circuit and generates an alternating current. The rotor moves in a mandatory direction which is perpendicular to the plane into which lies the magnetic circuit. Thus Lenz's reaction created into the magnetic circuit from collecting windings is always directed in perpendicular direction relatively to the direction of moving of the rotor, which means less input power is needed from the prime mover.

Because of the specific particularities of the rotor, low revolutions per minute are needed for induction of the alternating current. The stator can be configured from many independent magnetic circuits which means that they can be configured in many other different phase conFigurations. The physical qualities of the generator include no slip rings or brushes and fewer moving parts, which make it more reliable, easier to service and quieter, Similarly, since tis smaller and lighter, it is adaptable for applications with limited space and has an enhanced portability. Its operational characterstics include the use of a smaDer prime mover to obtain th.e same power output, higher efficiency, ower operating costs, higher reliabUity. ower initial cost arid quieter operation.

SUMMARY OF THE INVENTION

This invention relates to an AC generator with transverse flux switched reluctance of a plurality of magnetic circuits for production of an alternating current so that, due to the constructive particularities, the variation or switching of the magnetic flux needed for an induction process is achieved through a mechanical movement between two halves of a magnetic circLrit which two halves are a magnetic switch. Every one magnetic circuit contains a permanent magnet, a core divided into two halves and air gap between these two halves connected in a close loop which lies in a plane. Generally for switching of the magnetic flux flowing nto this magnetic circuit is needed relative movement between these two halves of the magnetic circuit. In a common case one half is stationary and it is connected to the stator. A collecting winding is coiled transversely to the direction of flowing of the magnetic flux on the stationary hail of the core. The other hail of the core is movable and it is connected to the rotor.

The rotor contains ordered halves core and empty spaces between them. In a process of moving of the rotor relatively to the stator the reluctance of the magnetic circuit changes itself periodically and alternating current is induced into the collecting winding coiled on stationary half of this magnetic circuit. Every one magnetic circuit can be spaced at a different distance to the next one and therefore appears a phase difference between these two alternating currents induced into these two independent magnetic circuits. Thus can be configured multiphase AC system. That half of the magnetic circuit which collects produced electricity by collecting windings on it is a stationary half therefore of that electricity can be collected without brushes. The stator contains a plurality of independent magnetic circuits. Every one magnetic circuit lies in a plane in parallel to next one plane and its magnetic circuit. Every plane and its magnetic circuit remain transversely to the direction of movement of the rotor. Thus the Lenz's reaction remains perpendicularto the direction of movement of the rotor, not against it ILKe in standard electric generators, which. means less input mechanical power is needed for production of electricity comparable to existing technologies and methods for production of the same quantity of electncity.

According to the invention a first embodiment of a multiph.ase, brushless. AC generator, applicable for Rail Systems is composed on board of a carnage, for powering of all board consumers. The carriage moves on a rail system driven by a locomotive. Iii this case, for brushiess collecting of produced electricity on the carriage is situated collecting winding with its half of the magnetic circuit. The second half of the magnetic circuit needed for switching of the magnetic flux is on the raiI system. Rail system contains ordered halves of a magnetic core and empty spaces. This rail system can be built in preliminary selected trajectory or a special type of mathematical curve. When the carriage moves the second half of the magnetic circuit periodically switches the magnetic flux and induces AC into the colIecting winding on board of the carriage. In process of moving the magnetic circut lies in a piane which always remains perpendicuiar to the direction of movement. In this way the resistive load for the locomotive which drives the carriage remains ow. If powering of stationary object along the rail system is needed then the configuration can be reversed.

In the second embodiment, a rotational configuration of a rnultiphase bmushless AC generator is shown, wherein the stator with. coiled windings on it, is in a stationary position and the rotor is a rotating part of the magnetic switch. Thus induced AC in the windings is collected without brushes and it is proportional to the speed of movement and number ol the windings, the frequency of induced AC depends of number of magnetic switches arid a phase difference of induced AC depends of a space difference between the core halves with windings on them relatively to the rotating part of the magnetic switch.

in the third embodiment, there is shown a hub midtiphase brushless AC generator. This embodiment contains an outer rotating rotor and a stationary stator.

in the fourth embodiment there is shown a modular, brushless, multiphase, AC generator, wherein, can be added a numbers of modules, until needed generator power is reached.

These and other features of the present inventon can be best understood from the following drawings.

DETAILED DESCRIPT1ON OF THE DRAWINGS Referring to FIGS. 1 2 and 3 the multiphase brushiess AC generator of the present invention generally includes a magnetic circuit which contains two halves Ml and M2. One of these two halves Ml in one embodiment according to FIG.1 is connected to an unmovable base 5, thus it is stationary and it is named the stator. The second half M2 in this case moves relatively to the stator Mi and it is named the rotor. The half Mi contains a permanent magnet 3 situated in the middle of the half, two pieces of core I with high magnetic conductivity situated symmetrically to the magnet 3 and two collecting windings 2, coiled transversely to the direction of the magnetic flux F, electrically connected in series and symmetrically situated on pieces core 1 to the magnet 3. Thus the collecting windings 2 provide a brushless collecting of induced alternating current. The second half M2 contains a magnetic core I with high magnetic conductivity. These two halves Mi and M2 in process of relative movement to each other remains situated in parallel to each other and connected magneticahy by a changing air gap 4. A magnetic flux F flows from one pole of the magnet 3 to its opposite pole through magnetic core 1 and airgap 4, Thus Mi and M2 through air gap 4 create a magnetic circuitwith switching conductivity. When M2 is against Ml and they are in parallel position each to other, then the magnetic conductivity of the closed magnetic circuit is high and the magnetic flux F has its maximum. When M2 passes MI, but it is stiU in. parallel position to Ml the reluctance of the magnetic circuit changes its value. When the hall M2 is not in opposite position against Mi, but in parallel position, then the magnetic flux F has its minimum. Thus these two halves of the magnetic circuit Ml and M2 simultaneously are two halves of a magnetic switch which switches the conductivity respectively the reluctance olthe magnetic circuit. Switched magnetic reluctance ol the magnetic circuit inducts an alternating current into collecting windings 2. Thus, when there is relative movement between Mi and M2, then an alternating current is induced into collecting windings 2. That means that Ml can be rotor and M2 stator. When the reluctance of the magnetic circuit is switched, then a Lenz's reaction L is directed against the magnetic flux F. The Lenz's reaction L lies in the same plane G in which flows the magnetic flux F. Thus the Lenz' reaction L remains perpendicular to the direction of the relative movement of M2 to Ml. Thus a less input mechanical power is needed for generatincl of the same quantity of electricity comparable to standard methods in which the Lenz's reaction is in opposite direction of the input mechanical power. The halves Ml and M2 in the process of dynamic movement each to other have to be always in parallel. In case of a linear AC generator, this condition can be provded by a linear rail system 6 connected with M2, which connection holds M2 to be always n parallel movement relative to Ml. In this case the base 5 and the mall system 6 are connected by a wheel system for example which is not shown. In all next explanations this condition will be assumed.

Thus the chrection of flowing magnetc flux F. swtched reluctance of the magnetic circuit, respectively the Lenz's reaction remains transversely to the direction of the mechanical movement ft FIG. 2 shows a second embodiment of the magnetic circuit, wherein the permanent magnet 3 is situated in the middle of the half M2. In this case the collecting winding 2 is coiled transversely on the core I and provides a brushless coecting 01: induced alternating current. Switching of the magnetic rehictance of the magnetic circuit is provided in the same conditions as shown in FIG.1 FIG. 3 shows a third embodiment ola magnebc circuit wherein are used two magnets 3 connected magnetically in series. The first one is situated in the middle of Mi. The second magnet is situated in the middle of M2, In this case the magnetic flux F is biggerthan in FIG.1 and FiG. 2, which means more electricity can be generated if are provided needed sizes of the core I. Switching of the magnetic reluctance of the magnetic circuit is provided in the same conditions as shown in FiG,l FIG.4a shows one embodiment of a linear brushiess AC generator will': one magnetic circuit. This magnetic circuit contains one hail Ml connected to a base 5 as a stator and second half M2 connected to a rail system 6 as a rotor. The rail system 6 is connected to the base 5, These two halves Ml and M2 are connected magneticaHy through an air gap 4, which prodes switching mode of this embodiment. Switching of the magnetic reluctance of the magnetic circuit is provided in the same conditions as shown in HG.l FIG. 4h shows a graphic of the switched magnetic flux F into the air gap 4. The shape of this graphic is defined by the shape of the end faces of the cores thmugh which flows the magnetic flux F into air gap 4. The graphic ot the generated alternating current generally has an impulse shape and this shape is determined from the switched magnetic flux, from the inductance of the collecting windings 2, from the character of the load current, from the speed of the movement and from the parameters of the magnetic core 1. One possible shape of generated alternating current is shown in FIG. 4c. By modeling the improvement process and defining ot all needed parameters shown in this paragraph above, can be reached an approximate sinusoidal shape of generated alternating current as shown in FIG. 4d.

The rail system 6 is connected to the base 5.The rail system 6 provides that the halves M2 in the process of their movement to Ml always remains transversely to the direction of movement E. FIG. 5b shows the shape of induced sinusoidal pulses into collectin.g winding 2. As can be seen there is a pause g between every one sinusoidal impulse and the next one. The length of this pause g is defined by the distance 8 between these four halves M2. If this distance 8 is defined properly then the length g can he eliminated and an approximate sinusoidal shape of generated altern.ating current can be reached.

The rail system 6 provides that in the process of movement these four halves M2 remains transversely to the direction of movement E The halves Ml are connected to base 5. The rail systemS is connected to the base 5 The collecting windings of the halves Mi are connected in two couples A and B. The geometrical distance 9 between these two couples defines the phase difFerence between these two independently generated couples A and B. By modeling and calculations of this distance 9 can be reached a phase difference 180 degrees between A and B as shown in FIG. 7b.

The rail system 6 provides that in the process of movement these three halves M2 remains transversely to the direction of movement The halves Ml are connected to the base 5. This is the stator of the generator, which provides brushless collecting of the generated alternating current. Every half Ml generates its own independent alternating current, thus these are three independently phases A, B and C. The phase difference between every phase is defined by the geometrical length of the distance 9 between the halves Ml. By proper calculations and modeling of this distant-e 9, the phase difference between all three phases can be adjusted to he 120 degrees.

FIG. Sb shows a graphic of a three phase A, B ar.d C, hrushless, alternating current generator, where the phase difference is 120 degrees between all three phases FIG. 9a shows an embodiment of a linear, brushiess. four phase AC generator.

The rail system S provides that in the process of movement these four halves M2 remains transversely to the direction of movement D. The halves Ml are connected to the base 5. This is the stator olthe generator, which provides brushless collecting of the generated alternating current. Every one half Mi generates its own independent alternating current in the process of movement, thus there are four independent phases A, B, C and D The phase difference between every phase is defined by the geometrical length of the distance 9 between every half Ml.

This is the rotor of the generator The rotor of this generator is connected by bearings 12 to the stationary body ot the generator. The stationary body of the generator contains sx independent halves Mi connected in the same distances 9 to a ring 5 produced from nonmagnetic material. The ring 5 is connected to an unmovable base 5a. in this case the distance 9 is 60 degree between every one half Mi. This s the tator of this embodiment. This embodiment provides that in the process of rotation of ail 36 halves M2 every one of them remains transverseiy to the direction ci movement E. A switching process is prov;ded between every one half M2 when it passes to every one half Mi. Thus every half Mi generates its own alternating current.

Thus these independent six generating halves by their coHecting windings can be connected in different mulhphase systems. For example [these six collecting windrngs are connected in a system of three pairs of windings that means we have a three phase system clan AC generator. In this case every pair windings. contains two windings 2.. connected eiectricahy in series.

This embodiment of a rotating AC generator allows gen.eratin.g of 36 impulses from each collecting winding for every one revolution of the rotor. In case of velocity of the rotor 240 revolutions per minute we will have 4 revolutions per second and thus will be generated 144 (i.e. 4x36) impulses per second from every one coflecting winding, because per revolution are generated 36 mpulses. This particularity allows successful generating of this generator in condition of low input revolutions per minute. This embodiment of the generator is applicable for wind generators in direct drive mode for example. The stationary assembling of all six halves Ml allows brushless collecting of generated alternating current.
