Description
Technical field
The present invention relates to a kind of parts of generator, particularly a kind of disc magnetic balancer.
Technical background
Faraday in 1821 finds that electrified wire can rotate around permanent magnet, has invented magneto.The Hui Sitong of Britain in 1857 replaces permanent magnet with electromagnet, has invented electric excitation mode, has started new era of electro-magnetic motor.But above motor all is the instrument of power conversion.
The basic principle of existing generator all is conductor cutting magnetic line and induced electromotive force and produces electric current, and the enough mechanical energy of process need consumption of conductor cutting magnetic line is with the soft iron that overcomes the assembly conductor and the suction between the magnet.
Observe as long as carefully go; We can find an interesting phenomenon: the suction effect in magnetic field can not go to explain with classical mechanics simply; Under the prerequisite of not considering friction; If according to classical mechanics, rotor iron should be in the opposite direction, equal-sized by inhaling toward the power of magnets of stator and the required power that overcomes that rotor iron leaves magnets of stator, but in fact; This but can't oneself cancel out each other to seeming equal-sized power, so the generator cutting magnetic line need consume a large amount of kinetic energy.Yet,, can use a pair of magnetic field repulsive force in the opposite direction, equal-sized that it is offset though this can not oneself cancel out each other to opposite, the equal-sized suction of direction.
The present invention utilizes a pair of magnetic field repulsive force in the opposite direction, equal-sized to go the principle of a pair of magnetic field in the opposite direction, equal-sized of balance suction; For generator provides the disc magnetic balancer of suction between a kind of stator that can offset special topological structure and the rotor, make generator no longer rely on external impetus and can generate electricity voluntarily.
Summary of the invention
The present invention is achieved in that a kind of disc magnetic balancer; Mainly comprise rotating disk (2), magnets of stator (3,9) and rotor magnet (4), it is characterized in that: magnets of stator has two or more, is symmetrically or evenly distributed on track ring (5) or the end cap (8); The pole orientation of magnets of stator is for radially; Facing to casing, perhaps, the S utmost point faces toward the axle center facing to casing, the N utmost point to the S utmost point facing to axle center, the N utmost point; Symmetry or average mark are furnished with two or more pole orientation and are radially rotor magnet on the rotating disk, the pole orientation of magnets of stator is identical with the pole orientation of rotor magnet, and promptly magnets of stator and rotor magnet are set at and repel each other; Magnets of stator is that bar magnet, rotor magnet are bar magnet, and perhaps, magnets of stator is that bar magnet, rotor magnet are " U " shape magnet, and perhaps, magnets of stator is that " U " shape magnet, rotor magnet are bar magnet.
Said magnets of stator and rotor magnet are bar permanent magnet or bare electromagnet or " U " shape permanent magnet or " U " shape electromagnet.Permanent magnet is processed with ferrite or rare earth material, like barium ferrite, strontium ferrite, neodymium iron boron or the like.Electromagnet is made up of unshakable in one's determination and excitation winding, and the iron core of bare electromagnet is " worker " font, and the iron core of " U " shape electromagnet is " worker " font of distortion, and promptly " worker " word extends to a side, and centre unshakable in one's determination is wound with excitation winding.Unshakable in one's determination process with soft iron material, as being cast as an integral body with electrical pure iron, or become an integral body with silicon steel plate stacking, excitation winding forms with the enamelled wire coiling, like enamel covered wire, enamel insulated aluminium wire, enamelling alloy wire.
Magnetic balanced device of permanent-magnet disk that said disc magnetic balancer is single segment structure or dual segment structure or the magnetic balanced device of mixing exciter panel type or the magnetic balanced device of electric excitation disc type.The magnets of stator of the magnetic balanced device of permanent-magnet disk and rotor magnet all are permanent magnets, and the repulsion size of rotor permanent magnet and stator permanent magnet is fixed, and can not regulate repulsion through the size of regulating magnetic field intensity.Existing permanent magnet has electromagnet again in the magnetic balanced device of mixing exciter panel type, and permanent magnet is located on the rotor, and electromagnet is located on the stator, and perhaps, magnets of stator is made up of electromagnet and permanent magnet.The magnetic balanced device of mixing exciter panel type can be regulated the repulsion of magnets of stator and rotor magnet through the magnetic field intensity of regulating magnet.The rotor magnet and the magnets of stator of the magnetic balanced device of electricity excitation disc type all are electromagnet.Electricity excitation disc type magnetic balanced device provides in the coaxial electrical function under the prerequisite of rotor-exciting power supply and uses, and special brushgear should not be set, in order to avoid increase cost.
The disc magnetic balancer of single segment structure is because magnets of stator and rotor magnet when repelling each other, and rotating disk will bear bigger axial thrust, so bearing will adopt and can bear the bearing of radial load and axial load simultaneously, like taper roll bearing, angular contact ball bearing etc.
The magnets of stator of the disc magnetic balancer of dual segment structure has two groups, lays respectively at the both sides of rotating disk; Rotor magnet has one group or two groups, if rotor magnet has only one group, then rotating disk is provided with through hole, and rotor magnet is fixed in the through hole, and the both sides of magnet are exposed in the both sides of rotating disk; If rotor magnet has two groups, then two group rotor magnet are separately fixed at the both sides of rotating disk, and the pole orientation of two group rotor magnet is opposite; The pole orientation of two groups of magnets of stator is also opposite; Perhaps, the pole orientation of two group rotor magnet is identical, and the pole orientation of two groups of magnets of stator is also identical.When the pole orientation of two group rotor magnet was opposite, suitable magnetizing earlier reinstalled rotating disk, and when the pole orientation of two group rotor magnet was identical, suitable earlier magnet steel being fixed on the rotating disk magnetized again.Therefore the disc magnetic balancer of dual segment structure can adopt the bearing that can bear radial load because the both sides of rotating disk all receive repulsion.
Rotating disk is provided with and is used to inlay magnet steel or groove or through hole unshakable in one's determination, and rotor magnet is fixed on the rotating disk with the method for welding or glue; Track ring or end cap are provided with and are used to inlay magnet steel or groove unshakable in one's determination, and magnets of stator is fixed on track ring or the end cap with the method for welding or glue.
Because magnets of stator and rotor magnet repel each other, when rotor and stator all had permanent magnet, needs were with special method installation rotating disk or track ring.Rotating disk can be threaded to predetermined rotating shaft position with the method that is threaded, then with methods such as pin or screw or nut or spring washer or nylon washer or self-locking nut fix, locking and thrust.The also available method that is threaded of track ring is threaded to predetermined casing position, and does locking processing.
The magnets of stator of the magnetic balanced device of single segment structure is identical with the pole orientation of rotor magnet; If the S magnetic pole of magnets of stator faces toward casing facing to axle center, the N utmost point; Then the S magnetic pole of rotor magnet faces toward casing facing to axle center, the N utmost point; If facing to casing, then the N magnetic pole of rotor magnet faces toward casing facing to axle center, the S utmost point to the N magnetic pole of magnets of stator facing to axle center, the S utmost point.When magnets of stator and rotor magnet repelled each other, the main active force that rotor is produced was tangential torsional moment and the axial thrust that is parallel to axle perpendicular to axial plane.
The repulsion that magnets of stator and rotor magnet repel each other is two-way, when both near the time, stop mutually the other side near, when both leave, push off the opponent mutually.Two-way suction is opposite when repulsion that this is two-way and generator cutting magnetic line, the two-way suction that the two-way repulsion that therefore magnetic balanced device produces produces in the time of can being used for the generator cutting magnetic line of balance special topological structure.
The two-way repulsion that magnetic balanced device produces can be expressed with curve; The equidirectional maximum repulsion point, minimum repulsion point and reciprocal maximum repulsion point, the minimum repulsion point that produce are continuously linked up and be waveform; The different waveforms that all can cause two-way repulsion to produce of speed of the distance difference between the magnetic pole of magnetic balanced device, the difference of magnetic field intensity and rotor rotation are different; Can be sinusoidal wave; Also can not be sinusoidal wave, the height of ripple be represented the size of repulsion, the width means wavelength of ripple.The repulsion that magnetic balanced device produces is used for the suction that the balancing generator cutting magnetic line produces, if both waveforms are in full accord, representes that then repulsion and suction can cancel out each other fully.The characteristic of the suction ripple that repulsion ripple that magnetic balanced device produces and generator cutting magnetic line produce is different; The magnet spacing of magnetic balanced device is close more, and the repulsion wave height of generation is more little, and maximum repulsion is more and more littler; Minimum repulsion also is more and more littler; And the magnet of generator is close more, and the maximum suction that produces during cutting magnetic force is constant, and minimum suction is increasing.Therefore the magnet spacing of magnetic balanced device can not be too close, and the magnet of the generator that matches with it can not be too close.Spacing between the adjacent magnets of stator of general small-sized magnetic balanced device and the spacing between the adjacent rotors magnet are between 2cm to 5cm; Spacing between the adjacent magnet of miniature magnetic balancer is between 0.5cm to 2cm; Generally be not less than 0.3cm, the spacing between the adjacent magnets of large and medium-sized magnetic balanced device then reaches more than the 5cm.
The magnets of stator of magnetic balanced device is identical with the quantity of rotor magnet; Also can be inequality, but will be complementary with the ratio of the number of magnetic poles of generator stator and rotor, the suction synchronized generation that repulsion that magnetic balanced device produces can be produced with generator; For example: generator is 6/4 utmost point; The magnetic balanced device that matches is 6/4 utmost point, and generator is 6/6 utmost point, and the magnetic balanced device that matches is 6/6 utmost point or 6/2 utmost point.
The number of magnetic poles of magnetic balanced device is identical with the number of magnetic poles of generator; Also can be inequality; As long as suction with repulsion can produce simultaneously, enhancing synchronously, synchronously weaken just passable, as: the stator and rotor of magnetic balanced device are 6/2 utmost points, and the stator and rotor of generator are 6/3 or 6/6 utmost point.
The repulsion size of electric excitation type and the magnetic balanced device of composite excitation formula can be regulated; Through regulating the size of exciting current; Just can make magnetic balanced device stator and rotor repulsion identical with the size trend of the stator and rotor suction of generator; Therefore magnetic balanced device of electric excitation disc type and the magnetic balanced device of mixing exciter panel type are provided with outlet box (10) and field regulator, through regulating the voltage of input excitation winding, the magnetic field intensity of magnetic balanced device can be regulated.The general magnetic field intensity that only needs to regulate stator of electric excitation type and the magnetic balanced device of composite excitation formula just can reach the purpose of regulating the repulsion size.Field regulator generally is located at outlet box, and outlet box is located on the casing, and field regulator is located in the outlet box.
The repulsion size of the magnetic balanced device of permanent-magnet disk also can be regulated, but must adjust the distance of stator and rotor magnet with the method for machinery.
The electric current that inserts magnetic balanced device of electric excitation disc type or the magnetic balanced device of mixing exciter panel type is a direct current, and the magnetic field that electromagnet produces is the stationary magnetic field.
Rotor turntable and track ring are processed with non-magnet material or ferrimagnet.
Also can produce heat energy during the magnetic balanced device work of the electricity magnetic balanced device of excitation disc type and mixing exciter panel type, be located in the same casing as if magnetic balanced device and generator, then can common fan, cooling device such as fin.
General and the generator of magnetic balanced device is located in the same casing, and is coaxial with the rotor of generator, also can make special magnetic balanced machine, and independently casing, outlet box and fan are arranged, and is connected with generator through shaft coupling.
