Definitions
- This invention relates to a linear electric generator of the type disclosed in parent U.S. Patent Application Ser. No. 10/170,715, and more particularly to a linear electric generator that includes one or both of the following:
- the magnetic elements and windings are in linearly reciprocal motion relative to each other.
- This linear reciprocal motion causes a diamagnetic effect that resists the motion of the magnetic elements within the windings, reducing the electromotive force .
- the moving part of the generator is an armature consisting of a single magnet arranged to move linearly through a coil.
- the accelerating elements may be in the form of resilient elements, such as rubber plugs or metal springs situated at the ends of travel of the moving magnets to impart a mechanical rebounding force as the magnets engage the resilient elements and reverse direction, in the form of a magnetic material or system that generates a repulsive force as the moving magnets approach the end of their travel, or in the form of a combination of mechanical and magnetic elements.
- Such linear generators are compact and efficient, and can be used to convert motion of the generator into a source of recharging power for a variety of electronic devices, such as cellular telephones (which are the subject of copending U.S. Patent Application Ser. No. 10/170,717), personal CD players, handheld electronic game players, and the like.
- This eliminates the need to obtain charging power from the electrical power grid, saving energy and reducing pollution associated with electricity generation, and also promotes the use of rechargeable batteries, reducing environment hazards associated with disposable non-rechargeable batteries .
- a limitation on the commercial development of such power sources has been the relatively low magnetic efficiency of suitable sized and priced magnets and coils, which typically have a relatively low flux density and/or provide an inefficient distribution of magnetic lines.
- magnets or magnet/coil structures are known, such as the rare earth magnets disclosed in U.S. Patent No. 5,347,186 and 5,818,132; the composite armature and multiple coil structure of U.S. Patent No. 4,500,827; the wound magnetic core disclosed in U.S. Patent No. 4,709,176; or the composite coil and stack neodymium disc magnets disclosed in U.S. Patent No . 5,975,714, the previously proposed magnet and/or coil structures are generally expensive to manufacture and/or too large for the applications mentioned above. Further, while distribution of magnetic lines from a coil can be improved by adding a permeable material to the coil structure, the permeable material has the disadvantage not only of adding to the complexity of the structure, but also to the diamagnetic resistance effect.
- a linear electric generator made up of plurality of axially aligned windings and a multiple pole armature arranged to reciprocate linearly within the windings, and which further includes accelerating elements that may be in the form of:
- resilient elements such as rubber plugs or metal
- the multiple pole armature is made up of a plurality of individual magnets, each including a north pole and a south pole, arranged in series.
- a linear electric generator made up of a plurality of axially aligned windings surrounding and arranged to reciprocate linearly relative to a stationary multiple pole magnet structure.
- the multiple pole magnet structure preferably includes a single multiple pole magnet positioned within the axially aligned windings, and may further include parallel magnet structures positioned outside the windings, or coaxial magnet structure positioned both inside and outside the axially-aligned windings.
- the armature or stationary multiple pole magnet structures may be constructed of pairs of magnets joined by an adhesive, sintering, welding, soldering, bonding, or similar material or technique, or by any combination of two or more such joining methods, applied to a planar surface of at least one of the magnets such that like poles of the two magnets in the pair face each other to form pole structures.
- Pole structures of N-S alternate polarity are then joined at ends of the respective magnets to form a rectangular parallelepiped shaped multiple pole magnet.
- the flux density within such a magnet structure has been found to be substantially higher than that of a corresponding conventional four pole magnet structure .
- the winding may consist of a core-less or air core double winding structure in which the coil includes at least one first clockwise winding and at least one second counterclockwise winding in a multi-layered stacked arrangement that maximizes passage of the magnetic lines through the armature and/or stationary multiple pole magnet structure and facilitates the distribution of the lines to maximize interaction with flux in the armature and thereby generate maximum energy.
- Fig. 1 is a schematic diagram of a linear electric generator constructed in accordance with the principles of a first preferred embodiment of the invention, including a stationary coil and a movable multiple pole magnetic armature magnet with a series of N-S-N-S alternating arrangement.
- Fig. 2 is a schematic diagram of a linear electric generator according to a second preferred embodiment, including a stationary coil and a movable multiple pole magnetic armature magnet with a series of N-S-S-N alternating arrangement.
- Fig. 2A and 2B are cross section views of Fig. 2, taken along line IV-IV of Fig 2.
- Fig. 3 is a schematic diagram of a specific implementation of the linear electric generator constructed in accordance with the principles of the second preferred embodiment of the invention, including a movable coil and a stationary multiple pole magnetic stator structure with a series of N-S-S-N alternating arrangement.
- Fig. 4 is a schematic diagram of a variation of the generator of Fig. 3, including a plurality of stationary multiple pole magnetic stator structures with a series of N-S-S-N alternating arrangement.
- Fig. 5 is a cross-sectional view of the generator of Fig. 4, taken along line V-V.
- Fig. 6 is an alternate cross-sectional view of the generator of Fig. 4, also taken along line V-V.
- Fig. 7 is yet another alternate cross-sectional view of the generator of Fig. 4, taken along line V-V.
- Fig. 8 is a schematic diagram illustrating the construction of a multiple pole armature magnet or stator structure for use in the linear electric generators of Figs. 1-7.
- Figs. 9A and 9B are schematic diagrams of a multiple pole armature magnet or stator structure constructed using the method illustrated in Fig. 8.
- Fig. 10 is a schematic diagram of a multiple winding arrangement suitable for use in the linear electric generator of Fig. 1.
- a linear electric generator 1 includes a plurality of stationary coil windings 11 and movably multiple pole armatures 12, each made up of serially connected dipole magnets and/or N-S alternating single pole structures 14S and 14N.
- Figs. 2A and 2B show cross section views taken along line IV-IV of Fig.2.
- the serially connected dipole magnets may optionally be constructed of pairs of dipole magnets, as illustrated in Figs. 8, 9A and 9B and described below.
- the invention is not limited to multiple pairs of dipole magnets. Instead, the invention may be implemented by a single pair of pole structures.
- the linear electric generator 1 of the two preferred embodiments as shown in Figs. 1 and 2 includes accelerating elements 13A and 13B at each end of the windings, in the path of the respective armatures 12 as shown in Figs. 1 and 2.
- the accelerating elements 13A, 13B may be made of a resilient material such as rubber, springs, or a combination thereof, a magnetic material or system which will generate a repulsive force against the armatures 12, or a combination of resilient and magnetic elements.
- the accelerating elements may also be part of a machine, device, or system for generating the rebounding or repulsive force.
- the windings 11 of this first embodiment may be movable and the armatures 12 may be stationary, with the accelerating elements being arranged for the windings 11 and generate a repulsive force against the windings rather than the armatures.
- the stationary coil and movable armature magnets of Figs. 1 and 2 may be replaced by a stationary multiple pole magnet structure 32 positioned within a movable coil or coils 31, as illustrated in Fig. 3.
- the stationary multiple pole magnet structure 32 may have the same construction as the multiple armature of Figs. 1 and/or 2, but is fixed with respect to a housing (not shown) .
- the accelerating elements (not shown) can also be arranged for generating the repulsive force against the movable windings 31.
- the configuration of these accelerating elements may be, but are not required to be, similar to those of described in connection with armatures 12 in Figs 1 and 2.
- the generator of Figs. 2 and 3 may be modified to include additional stationary magnet structures 42 which are not limited to one layer of magnet structure and can be positioned outside the coil(s) 31, as illustrated in Figs. 4 and 5.
- Magnet structures 42 are also constructed of multiple serially connected dipole magnets, although the individual dipole magnets need not necessarily have the same construction as those of the central magnet structure.
- Fig. 6 shows a variation of the generator structure illustrated in Figs. 4 and 5, in which multiple pole magnet 32 is made up of two half cylindrical structures joined together, and in which multiple pole magnet 42 has a hollow cylindrical structure including two arc-shaped structures oined together, co ⁇ l(s) 31 and magnets 32 and 42 being coaxially aligned.
- the external magnet structure may consist of multiple magnets 42 having approximately semi-circular cross-secti o ns, or be replaced by multiple magnets (not shown) having arc-shaped cross-sections that extend around a third, quarter, or smaller sections of the circumference of the generator. It will of course be appreciated by those skilled m the art that the multiple magnets 42 are not restricted to the illustrated shapes.
- the pole magnet structures 12, 32, or 42 of any of the embodiments illustrated in Figs. 1-7 are preferably constructed of N-S alternating series-connected pairs of magnets 1,2; 3,4; and 5,6 that form pole structures 14S and 14N of Figs. 9A and 9B.
- Each pair of magnets 1,2; 3,4; and 5,6 consists of at least two individual parallelepiped-shaped dipole magnets having ends 7, 8 and laterally oriented like and/or opposite magnetic poles between the ends and/or, m the case of cylindrical magnet structures, individual half-cylindrical dipole magnets (not shown) having ends corresponding to ends 7,8 and laterally oriented like and/or opposite magnetic poles between the ends.
- the alternating pole structures may be made by magnetizing a metal core, or in a preferred method by joining separately magnetized pole structures, although the invention is not intended to be limited to a particular method of forming or constructing the alternating poles structures.
- Each magnet in a pair is joined to the other -nember of the pair by coating of an adhesive on at least one lateral face 9 of one of the magnets, or by welding, bonding, soldering, sintering, or any other suitable joining method, or by any combination of two or more different joining methods, such that like poles of the respective magnets face each other.
- the pairs of magnets 1,2; 3,4; and 5,6 are joined together in series by adhering, welding, bonding, soldering, sintering, or the like or by performing combinations of any two or more of i he above joining methods on respective ends 7, 8 of the magnets together to form the multiple pole magnetic armature 12 or multiple pole magnetic stator structures 32.
- the flux density of the illustrated multiple pole magnet structure is substantially higher than that of a multiple magnet structure that is not constructed of pairs of individual magnets in the illustrated manner.
- a first winding 11A may be wound in a clockwise direction
- a second winding 11B may be wound in a counterclockwise direction when viewed along an axis of the coil
- a third winding 11C may be wound in a clockwise direction
- a fourth winding 11D may be wound in a counterclockwise direction.
- the spacing and number of windings 11 and/or 31 can easily be adjusted depending on the spacing and number of poles of the respective pole magnet structures 12 and/or 32 to optimize distribution of magnetic lines for a simulated motion of the pole magnet structures in order to achieve an ideal magnetic line cutting efficiency and maximum energy output for the generator.
- the number of windings of the invention is not to be limited to that shown in the drawings, so long as at least one coil winding is included.
- the windings may be at least one layer of a multi-layered stacked arrangement.
- the windings 11 and/or 31 are preferably not provided with a permeable material .
- the individual dipole magnets and pairs of dipole magnets may be joined together by means other than the use of adhesives, such as by welding, soldering, bonding, or sintering, or by any combination of two or more such joining methods.
- the number of magnetic pole structures may be any number greater than one, i.e., at least two, and the structural shapes of pole magnets are not limited to those of the above embodiments, but rather may include triangular, elliptical, or other geometric shapes.
- the arrangement of pole magnet structures is also not limited to N-S-N-S and/or N-S-S-N polarity, but rather can extend to other combinations of N-S alternating polarities. It is therefore intended that the invention not be limited by the above description or accompanying drawings, but that it be defined solely in accordance with th ⁇ appended claims .
