In one of preferred implementation of the present invention, outside coil block 100, magnetic steel component 200, it is provided with shell.
Beneficial effects of the present invention are：
（1）Current wind-driven generator, due to the combination mounting means using conventional winding configuration and magnet steel, is generating electricity
During machine work, inevitably produce substantial amounts of heat, these mainly have:The eddy-current heating being produced by yoke, machine driving is produced
Raw frictional heating, conductor resistance generates heat. and main heat is to be produced by the first two. and magnet steel of the present invention is fixed on yoke
On, and be fixed on together with yoke in rotating shaft, produce the magnetic field of constant homogeneous in the middle of the air gap of a pair of magnet steel, vortex is not sent out
Heat. due to being that fan blade directly drives rotating shaft, there is no speed increasing mechanism, mechanical friction is only the friction of bearing, so frictional heating
Will very little. the structure design of the therefore present invention determines the caloric value of a whole set of electromotor compared with conventional design, can greatly reduce,
Requirement to cooling will reduce a lot.
（2）The magnet steel combination of the present invention and mounting means, make the utilization rate of the magnetic energy of magnet steel have great raising. and magnet steel is several
All of magnetic field all concentrates in the middle of two groups of magnet steel and the air gap of yoke composition, stray magnetic field very little. magnetic field intensity in air gap
Uniformly, intensity is big, and large-scale wind-driven generator can reach more than 12000Gs, and miniature wind-driven generator can also reach
More than 6000Gs. the efficiency of wind-powered electricity generation can be improved in high and uniform magnetic field, be follow-up rectification and unsteady flow provide stable and abundant
The energy.
（3）Due to the unstability of wind-force, wind-force very little sometimes, sometimes and very big, 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, does not start, and wind speed is high, probably
Burning apparatus, forced stoppage. and the present invention can solve this problem, makes wind-driven generator that wind speed requirement is substantially reduced, wind
The available scope of speed greatly improves. and specifically method is:The multigroup coil of each wind power generation unit exports, a whole set of wind-power electricity generation
The output group number of machine will be a lot. again by peripheral control system according to the output voltage of every group of coil, carry out varying number
Coil output series connection, to reach metastable output voltage in certain limit. again these are reached the line of requirement output voltage
Circle group carries out parallel connection, has just reached the purpose increasing output, as high as possible make use of wind energy. for example:In minimum wind speed
When, can there are 360 coil series connection, export 380 volts of voltages, in high wind speed, 2 coil series connection just can reach 380 volts of voltages,
At this moment can there are 180 groups of Parallel opertation, export high power.
（4）Common wind generator design, because the heating of whole machine is very big, needs the magnet steel adopting to require very high,
Ask high magnetic energy product and the long-term work of very high Hc (coercivity) ability normal table, and the price of this magnet steel be very high,
The cost that this has resulted in whole typhoon power generator is very high. and the requirement to magnet steel for the present invention is not just high, using the N trade mark or the M trade mark
Nd-Fe-B magnet steel just can normal work. in the expense of magnet steel, 50% about can be saved. and routinely design, using SH board
Number neodymium iron boron, the magnet steel cost of whole typhoon power generator is generally 25% about.
（5）The wind-driven generator being commonly designed in the past, its magnet steel is mounted on the circumference of rotor, and rotor turns in high speed
When dynamic, very big centrifugal force can be produced, it is very firm that this requires one side magnet steel must be mounted so as to, to prevent magnet steel from loosening,
Extreme care again, to prevent too big coupling mechanism force from magnet steel is caused damage. and on the other hand, the length due to rotor compares
Long, whole rotor must do dynamic balance running, time of consuming and costly. and magnet steel of the present invention is arranged on the plane of thin discs
On, draw ratio very little, as long as it is just permissible to do static balance. facilitate installation and the debugging of magnet steel. in addition stress during working rotor
Direction is also entirely different with conventional, is simply subject to lateral power, and this power is easy to eliminate. in addition two groups of magnet steel and
Yoke relative makeup, in the air gap between them, uniformly, intensity is high for magnetic field intensity, and can according to different coil dimensions,
Adjust different air gaps, the design of very convenient coil.
（6）The wind-driven generator being commonly designed, because coil is in the wire casing be embedded in silicon steel sheet, between silicon steel sheet and magnet steel
Captivation very big, and have dead point. so wind-driven generator start the wind-force it is necessary to have very big. meanwhile, according to data,
The utilizable wind-force of maximum of current wind-driven generator is also very low, about arrives storm, then cannot utilize greatly. the present invention
Coil in do not have ferrimagnet, coil and Magnet there is no active force, so the wind-force of very little just can be with starter-generator. and
And, the various combination being exported by coil, high output can be born. so wind-driven generator working range aweather
Power is little and the big both direction of wind-force extends, and greatly increases the utilization rate of wind energy, also improves the utilization rate of wind-driven generator,
Largely save the cost of wind-power electricity generation.
（7）In the present invention, as previously discussed, when wind speed is very low, the rotating speed of main shaft is very slow, at this moment every group of coil
Output voltage is very low, and at this moment very low voltage is that almost do not have value, but if the electricity hundreds of coil output
Pressure is together in series (i.e. voltage adds up) so that it may to obtain the output having value of certain voltage value. in very high wind speed,
The rotating speed of main shaft is very high, and at this moment the output voltage of a coil is possible to reach volts up to a hundred even hundreds of volt, so only
The output having a several or coil has just reached output and has required, at this moment several coils be connected into one group in parallel or even every again
Individual coil is all together in parallel, and wind-driven generator just has high output. the stator coil of wind-driven generator is divided into many
Group coil, then it is connected respectively to control system, control system, according to the output voltage size of every group of coil, is grouped, and carries out
Serial or parallel connection, can greatly improve the working condition of wind-driven generator, improve the performance of wind-driven generator, wind-driven generator
Output energy can have the change of hundred times.
（8）Coil directly does cutting magnetic line movement in almost parallel magnetic field, due to not having iron core, rotor in coil
Magnet will not be attracted by the iron core in conventional design coil. so in theory, the wind-driven generator of the present invention, can be atomic
Wind-force in start, as long as overcoming the resistance of bearing both can work.
（9）According to introduction above, the wind-driven generator of the present invention, the power of its output from minimum to maximum, Ke Yiyou
1000 times of gap. thus it minimum can in gentle breeze power normal work it is also possible in 11 grades of even above high wind work
To make. when working in high wind, due to not having gear speed increasing mechanism, the rotating speed of fan blade also will not infinitely improve, thus without appearance
The phenomenon of driving beaten by generator amature.
（10）In the present invention, by the rotor of fan blade direct drive generator, the construction of electromotor and its simple, only yoke
Ferrum and the rotor of magnet steel composition, stator coil, the casing of positioning rotor and coil, suitable cooling system forms, so entirely
The structure of electromotor is very compact, the very light in weight of electromotor. and this creates great convenience to the installation of electromotor and maintenance. and
Greatly save manufacturing cost.
（11）Because most of the time, wind-force is smaller, the rotating speed of fan blade can be very low. therefore conventional wind-driven generator
Design, need the speed increasing mechanism of a lot of gears composition, to improve the rotating speed of rotor, to reach available output voltage, this
Sample, during gear drive, causes a lot of energy losses, increased heating, abrasion, noise etc. in the present invention, due to
The coil employing uniqueness divides multigroup and has the method for control system intelligences combination so that generator amature is in very low rotating speed
Under, also can obtain available output voltage it is possible to gear speed increasing mechanism is omitted, meanwhile, electromotor under high wind
Rotor is also not in driving phenomenon. so, will be without being produced by machinery in operation in mechanically operated energy loss
Noise also disappear, the deadweight of electromotor also eliminates a greater part of, cost also much lower. and eliminate machinery speed increasing portion
Point, the maintenance period of electromotor also becomes to grow very much very long. and conventional wind-driven generator, gear up part is often out of order
Local.
（12）In the present invention, because without eddy-current heating, the frictional heating of machinery, all of is only that coil has electricity
Ohm heating when stream flows through, the heating power of therefore electromotor greatly reduces, and the heat sending also greatly reduces, such cooling system
The burden of system is just very light, and cooling system just can be designed to very simple.
（13）In the present invention, because heating is few, cooling system can be very simple, even without cooling system, therefore
Electromotor can be produced into closed type, so the life-span extending electromotor is very helpful. simultaneously because there is no machine
Tool running part, generator operation is that noise also has great reduction.
（14）In the diagram it can be seen that, present invention design is simple, easy to process, simple and convenient assembly, therefore electromotor
Low production cost.
（15）The present invention relates to a kind of electromotor, can apply to stablize the energy, such as hydroelectric generation, turbine generator, also may be used
To apply in the unstable energy, such as wind energy, tide energy, wave energy etc. being of wide application of electromotor.
