CN102820834A - Magnetic levitation generator - Google Patents

The invention provides a magnetic levitation generator and relates to the field of generators. The magnetic levitation generator is composed of a generator rotor, a generator stator, a magnetic levitation track, a magnetic levitation running device and the like. When the generator is driven by a hydraulic turbine, a steam turbine, a diesel engine or other motive power machines, the generator rotor is in a levitation state, so that running speeds of the generator rotor are increased, consumption costs are reduced, and a generating capacity is increased; and the magnetic levitation generator has the advantages of being high-speed, lubrication-free, abrasion-free, pollution-free, high-accuracy, long in service life, low in cost, large in generating capacity and applicable to electricity generation in various areas.

Magnetic suspension generator

The technology neck

The invention provides a kind of magnetic suspension generator, relate to electrical generator fields.

Background technology

electric energy is one of topmost energy of modern society.Generator is the plant equipment that other forms of energy conversion is become electric energy; It is driven by the hydraulic turbine, steam turbine, diesel engine or other dynamic power machines, with current, and air-flow; The Conversion of energy that fuel combustion or nuclear fission produce is that mechanical energy is passed to generator, converts electric energy into by generator again.Generator is in industrial and agricultural production, and national defence has been widely used in science and technology and the daily life.Along with the fast development of modern economy, human demand for electricity increases rapidly, and China's some areas power cuts to limit consumption situation is serious at present, and some local appearance lack coal and shut down phenomenon, and how to address this problem is worth our thinking.Existing all kinds of generator; Because the rotor of generator is made up of materials such as iron pivot, coil windings, links, quality is heavier, particularly the rotor of high-rating generator from hundreds of tons to thousands of tons of; All drive by the hydraulic turbine, steam turbine, diesel engine or other dynamic power machines; Have a strong impact on running speed, cause energy output little, the problem that consuming cost is big.Therefore, for realizing sustainable development, developing new generator is the new problem of modern society.

Summary of the invention

Existing all kinds of high-rating generator volumes are big, quality heavy, influence running speed in order to solve , cause energy output little, the problem that consuming cost is big.The invention provides magnetic suspension generator, form by generator amature, generator unit stator, magnetic-levitation, magnetic suspension performer etc.When generator was driven by the hydraulic turbine, steam turbine, diesel engine or other dynamic power machines, generator amature was in suspended state, has not only increased the speed of service of generator amature, and reduced consuming cost, had improved energy output.

the technical solution adopted for the present invention to solve the technical problems is: magnetic suspension generator advances magnet, magnetic suspension stator core armature winding, magnetic-levitation, dynamo bearing, generator rotor support fixture, magnetic suspension performer, guiding and braking orbit, guiding and braking, support etc. to form by dynamo bearing connector, generator amature, generator unit stator, magnetic suspension.Because the rotor of generator is made up of materials such as iron pivot, coil windings, links; Quality is heavier; Particularly the rotor of high-rating generator, is all driven by the hydraulic turbine, steam turbine, diesel engine or other dynamic power machines to thousands of tons of from hundreds of tons, and the quality of rotor is heavy more; The actuating force that needs is big more, has a strong impact on running speed.In order to reduce actuating force, improve running speed, utilize the principle of " like pole repels each other; opposite pole is inhaled mutually "; Generator amature is suspended, so only need the actuating force seldom just can be the rotor driven of generator, thus the running speed of raising generator amature; Increase generated output, reduce cost of electricity-generating.Magnetic suspension generation machine rotor, dynamo bearing, generator rotor support fixture link to each other with the magnetic suspension performer; When magnetic suspension performer during along track operation; Let magnet have gravitational ability of resistance; After being contained in the magnetic suspension stator core armature winding energising of magnetic-levitation below, on the polarity of the magnetic field that magnetic suspension stator core armature winding produces and the magnetic suspension performer magnetic suspension being installed and advancing the total maintenance of electromagnet polarity between the magnet identical, both " same sex is repelled each other "; Repulsive force suspends generator amature; When generator amature suspends, only need the generator actuating force seldom of the hydraulic turbine, steam turbine, diesel engine or the driving of other dynamic power machines just can make the rotor running, rotor begins generating when in stator, turning round.Stable in order to ensure generator amature, guiding is installed in the magnetic-levitation both sides and the corresponding with it magnetic suspension performer of braking orbit is provided with guiding and braking.

the invention has the beneficial effects as follows: adopt magnetic suspension generator, have high-speed, unlubricated, do not have wearing and tearing, pollution-free, high accuracy, long-life, advantage such as cost is low, energy output is big.Be applicable to the generating of all kinds of areas.

further specify the present invention below in conjunction with accompanying drawing and embodiment.
