Abstract
The invention relates to a wind wheel, which has the structure that a rotor 1 of a dynamo magneto which is made of composite materials and a casting hub G of a wind wheel F are bonded into a whole toensure proper alignment; a plurality of strip-shaped permanent-magnets 4 are axially arrayed on the inner side of an outer ring 3 of the rotor 1 in a bonding way. A plurality of stator slots and windings 24 are arranged on a cylindrical surface of the outer ring 23 of a stator 20 relative to the strip-shaped permanent-magnets 4; therefore, when the rotor 1 and the wind wheel F rotate together, thelines of magnetic force of the permanent-magnets 4 are cut by the winding of the stator slots 24 to generate electric current (a low-speed multi-polar generator), an inner hole of a stator axle hub 21 fastens a main shaft A with the centering effect together through a bulging joining sleeve 22, so as to share the same center with the rotor. The application figure 3 shows the outer stator and inner rotor type which is the transformation of the same structure. The proposal (of two types) provided by the invention is that: firstly, neither gear nor engine compartment exists in the invention, themain shaft is not driven, and the wind wheel can run in the wind energy under the temperature below minus 20 DEG; secondly, the main shaft which only plays the role of centering is applied to the transverse extension of a big wind wheel axis cantilever.
Description
Technical field
The invention belongs to the wind-powered electricity generation field, a kind of wind wheel-permanent magnet generator is the rotor one of kind of wind wheel and permanent magnet generator, and stator also is coaxial.
Background technology
As if authoritative wind-powered electricity generation unit is all used the cabin, and in view of present normal temperature and low temperature wind-powered electricity generation unit down running, non-gear box, protection against the tide is no longer very main: the moisture barrier coatings of generator, insulation property can be very high, high-voltage generator is also harmless.The volume of the multipole permanent magnet generator of low speed is big, allow its natural draft, except necessary protective cover, for sandstorm, reinforcement along with environmental practice, thumping majority ocean from now on, the wind in territory, coastal waters can be cleaner quiet, so the human wind energy that makes full use of below-20 ℃ is also very important, so it is meaningful for manufacturing enterprise's selection to propose the wind-powered electricity generation unit of multiple non-gear box.
Summary of the invention
The invention provides a kind of wind wheel-permanent magnet generator, its technical scheme is: comprising: rotor, permanent magnet and stator and winding thereof, rotor is made by composite material and be gluing with the wind wheel wheel hub is one, form wind wheel and the same wheel hub of rotor, and with the same main shaft of stator, guaranteed wind wheel, rotor and stator three's axiality, air gap value; This main shaft only plays to be decided the core effect and fixes, and is well suited for that wind wheel maximizes, the large span cantilever is horizontal stretches; Described rotor supports wheel rims with three spoke shelves that the blade function effect arranged, on the inside circumference of this wheel rim, and with rotor axis many bar shaped permanent magnets that are being arranged in parallel, many stator slots on the excircle of relative with this permanent magnet is internal stator and winding; Described stator is provided with three spoke shelves that are streamline section, presses Y shape and installs; The same wheel hub of described rotor and wind wheel is the structure that rotor is supported stretching type wind mill wind wheel, and this wind wheel back stretch-draw line stretch-draw simultaneously owing to the effect of stretch-draw line, has improved the moment of torsion of wind wheel wheel hub in rotor spoke shelves outer end.
Described rotor and stator are respectively external rotor, internal stator structure or external stator, inner rotor core; The rotor of two patterns all with the same wheel hub of wind wheel, coaxial with stator and main shaft.
Advantage of the present invention: 1. without gear, not driving main shaft, do not establish the cabin; 2. rotor, wind wheel totally one wheel hub, and with stator totally one main shaft, so guaranteed to be mutually axiality, guarantee the power generator air gap value; 3. the back of stretching type wind wheel (right side of Fig. 1 or Fig. 3) stretch-draw line (representing with double dot dash line) just in time is pulled in three spoke shelves outer ends of rotor, is the stretch-draw function, improves the moment of torsion that the wind wheel wheel hub drives rotor simultaneously again; 4. the gear box wind energy conversion system is-20.Must decide machine below ℃, this programme then can make full use of-20 ℃ of following wind energy advantages; 5. only work the fixed main shaft of deciding the core effect, be well suited for that cantilever is horizontal in the wind wheel maximization stretches.
Description of drawings
Fig. 1 is wind wheel-permanent magnet generator side view.
Fig. 2 is the stereogram of stator, main shaft, tailing column C.
Fig. 3 is a kind of variation of wind wheel-permanent magnet generator: i.e. the side view of external stator, internal rotor pattern.
Embodiment
Fig. 1 is a generator amature 1, it and the shared wheel hub G of wind wheel F, rotor 1 supports wheel rims 3 with three (the blade function effect is arranged) spoke shelves 2, on 3 inside circumference, with rotor axis many bar shaped permanent magnets (as neodymium iron boron) 4 that are being arranged in parallel, many stator slots on the excircle 23 of relative with 4 is internal stator 20 and winding 24 are so when rotor 1 rotated with wind wheel F, the magnetic line of force of permanent magnet 4 was produced electric current (low speed multipolar generator) by the cutting of the winding of stator slot 24.
Annotate: the spoke shelves of the rotor of Fig. 1, stator, express the symmetrical profile up and down that 120 ° three spoke shelves between mutually is drawn as main shaft easily for view.W represents wind direction, and F is a stretching type wind mill wind wheel, (applying date is on December 25th, 2007).
Fig. 2, three spoke shelves 25 of internal stator 20 are streamline section, press Y shape and install, vertical spoke shelves back reinforcement 25a, be cast with splayfoot 26 and base plate 26a below outer ring (at the casting position of the back of stator slot) 23, base plate 26a is installed on the control tower B, with the same table top of tailing column C of principal axis A; 26b is the stretch-draw line, and D is a pylon.
The endoporus of the propeller boss 21 of stator 20 tightens together the principal axis A of deciding the core effect with bulging joining sleeve 22.Rotor 1 also has three spoke shelves 2, and spoke shelves 2 are the airfoil type cross section, also gradually reverse as the outer tip of blade because rotor entirely with composite material make, light weight, make to produce one auxiliary rotatory force.
Fig. 3 is in rotor 1 is illustrated in, stator 20 outside, sequence number is represented identical with Fig. 1.
