In one of them preferred implementation of the present utility model, coil block 100, magnetic steel component 200 are outside equipped with shell.
The beneficial effects of the utility model are:
(1) present wind-driven generator, owing to adopt conventional winding configuration and the combination mounting means of magnet steel, when generator is worked, inevitably produce a large amount of heats, these mainly contain: by the eddy-current heating of yoke generation, the frictional heating that machine driving produces, the conductor resistance heating. and main heat is to be produced by the first two. and the utility model magnet steel is fixed on the yoke, and be fixed on together in the rotating shaft with yoke, in the middle of the air gap of a pair of magnet steel, produce constant uniform magnetic field, there is not eddy-current heating. owing to be that fan blade directly drives rotating shaft, do not have speed increasing mechanism, mechanical friction only is the friction of bearing, so frictional heating will be very little. therefore structural design of the present utility model has determined that the caloric value of a whole set of generator is compared with conventional design, can greatly reduce, will reduce a lot to the requirement of cooling off.
(2) magnet steel combination of the present utility model and mounting means, make the utilance of magnetic energy of magnet steel by great raising. the nearly all magnetic field of magnet steel all concentrates in the middle of the air gap that two groups of magnet steel and yoke form, stray magnetic field is very little. air gap internal magnetic field even intensity, intensity is large, large-scale wind-driven generator can reach more than the 12000Gs, miniature wind-driven generator also can reach more than the 6000Gs. high and uniformly magnetic field can improve the efficient of wind-powered electricity generation, for follow-up rectification and unsteady flow provide stable and the abundant energy.
(3) because the unsteadiness of wind-force; wind-force is sometimes very little; sometimes very large again; cube being directly proportional of wind energy and wind speed. therefore; the wind-driven generator of conventional design; the wind speed range that can utilize is very narrow. and wind speed is low; do not start; the wind speed height; fear burning apparatus; want forced stoppage. the utility model can address this problem; requirement reduces greatly to wind speed to make wind-driven generator; the scope utilized of wind speed improves greatly. and concrete method is: each wind power generation unit is organized coil output more; the output group number of a whole set of wind-driven generator will be a lot. again by the control system of the periphery output voltage according to every group of coil; carry out the coil output series connection of varying number; to reach metastable output voltage in the certain limit. again these coil groups that reach the requirement output voltage are carried out parallel connection; just reached the purpose that increases power output; high as far as possible utilization wind energy. for example: when minimum wind speed; 360 coil series connection can be arranged; export 380 volts of voltages, when high wind speed, 2 coil series connection just can reach 380 volts of voltages; at this moment 180 groups of outputs in parallel can be arranged, export high power.
(4) common wind generator design, because the heating of complete machine is very large, the magnet steel that needs to adopt requires very high, requirement has high magnetic energy product and very high normally stable long-term work of Hc (coercive force), and the price of this magnet steel is very high, this has just caused the cost of whole typhoon power generator very high. and the utility model is just not high to the requirement of magnet steel, use the Nd-Fe-B magnet steel of the N trade mark or the M trade mark just can work. on the expense of magnet steel, can save about 50%. and routinely design, use the neodymium iron boron of the SH trade mark, the magnet steel cost of whole typhoon power generator is usually about 25%.
(5) wind-driven generator that usually designs before, its magnet steel is mounted on the circumference of rotor, rotor is when high speed rotating, can produce very large centrifugal force, this just requires the one side magnet steel must install very firmly, loosening to prevent magnet steel, extreme care again, to prevent that too large coupling mechanism force is to the magnet steel injury. on the other hand, because the length of rotor is long, whole rotor must be done dynamic balance test, and the time of expending and expense are very high. the utility model magnet steel is installed on the plane of thin discs, draw ratio is very little, as long as do static balance with regard to passable convenience the installment and debugging of magnet steel. be subjected in addition also complete different with routine of force direction during working rotor, just be subject to the power of side direction, and this power be easy to eliminate. assemble relative with yoke of other two groups of magnet steel, in the air gap between them, magnetic field intensity is even, and intensity is high, and can be according to different coil dimensions, adjust different air gaps, easily the design of coil.
(6) wind-driven generator that usually designs, because coil is to be embedded in the wire casing of silicon steel sheet, attraction between silicon steel sheet and the magnet steel is very large, and the dead point arranging. the startup of wind-driven generator must have very large wind-force like this. simultaneously, according to data, the maximum utilizable wind-force of present wind-driven generator is also very low, approximately to storm, just can not utilize greatly again. there is not ferrimagnet in the coil of the present utility model, coil and magnet do not have active force, so very little wind-force just can starter-generator. and, various combination by coil output can bear high power output. and the working range of wind-driven generator is expanded with the large both direction of wind-force to wind-force is little like this, has improved widely the utilance of wind energy, also improve the utilance of wind-driven generator, saved to a great extent the cost of wind power generation.
(7) introduce such as the front, in the utility model, when wind speed is very low, the rotating speed of main shaft is very slow, at this moment the output voltage of every group of coil is very low, at this moment very low voltage is almost not have value, if but the Voltage Series of hundreds of coil output get up (being that voltage is added up), just can obtain the output that having of certain voltage value utilize to be worth. when high wind speed very, the rotating speed of main shaft is very high, at this moment the output voltage of a coil just might reach volts up to a hundred even hundreds of volt, only have like this output of several or a coil just to reach the output requirement, at this moment several coils form one group more in parallel even each coil be together in parallel, wind-driven generator has just had high power output. the stator coil of wind-driven generator is divided into many group coils, be connected respectively to control system, control system is according to the output voltage size of every group of coil, divide into groups, carry out serial or parallel connection, can greatly improve the working condition of wind-driven generator, improved the performance of wind-driven generator, the output energy of wind-driven generator can have the variation of hundred times.
(8) coil is directly done cutting magnetic line movement in almost parallel magnetic field, owing to do not have iron core in the coil, so rotor magnet can not attracted by the iron core in the conventional design coil. in theory, wind-driven generator of the present utility model, can in atomic wind-force, start, both can work as long as overcome the resistance of bearing.
(9) according to the introduction of front, wind-driven generator of the present utility model, the power of its output is from the minimum to the maximum, so 1000 times gap can be arranged. its minimum can normal operation in gentle breeze power, also can in 11 grades even above high wind, work. when in high wind, working, owing to there is not gear speed increasing mechanism, the rotating speed of fan blade can infinitely not improve yet, and therefore the phenomenon that generator amature is made driving can not occur.
(10) in the utility model, rotor by the fan blade direct drive generator, the structure of generator and simple, the rotor that only has yoke and magnet steel to form, stator coil, the casing of location rotor and coil, suitable cooling system forms, so the structure of whole generator is very compact, the very light in weight of generator. this installation and maintenance to generator has produced great convenience. and saved greatly manufacturing cost.
(11) because most of the time, wind-force is smaller, the rotating speed of fan blade can be very low. the therefore design of conventional wind-driven generator, the speed increasing mechanism that need to be formed by a lot of gears, improve the rotating speed of rotor, reach available output voltage, like this in the gear drive process, caused a lot of energy losses, increased heating, wearing and tearing, noise etc. in the utility model, owing to adopted unique coil to divide many groups and by the way of control system intelligences combination, so that generator amature is under very low rotating speed, also can obtain available output voltage, so can omit gear speed increasing mechanism, simultaneously, the rotor of generator the driving phenomenon can not occur yet under high wind. like this, will not have in mechanically operated energy loss, the noise that is produced by machinery in service has also disappeared, and the deadweight of generator has also been saved a greater part of, and cost is also low a lot. and removed the machinery speed increasing part, it is very long very long that the maintenance period of generator also becomes. and conventional wind-driven generator, gear up partly is frequent out of order place.
(12) in the utility model, owing to there has not been eddy-current heating, the frictional heating of machinery, ohm heating when coil has electric current to flow through that all only is, therefore the heating power of generator greatly reduces, the heat that sends also greatly reduces, and the burden of cooling system is just very light like this, and cooling system just can design very simply.
(13) in the utility model, because heating is few, cooling system can be very simple, even do not need cooling system, therefore can produce closed type to generator, like this life-span that prolongs generator is very helpful. be that noise also has great reduction owing to not having mechanical driving part, generator operation simultaneously.
(14) can find out in the diagram, the utility model simplicity of design, easy to process, simple and convenient assembly, so the low production cost of generator.
(15) the utility model relates to a kind of generator, can be applied to stablize the energy, and such as hydroelectric power generation, the steamer generating also can be applied in the unstable energy, such as wind energy, and tidal energy, wave energy etc. being of wide application of generator.
