Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the utility model wind generating unit electric generator structure schematic representation;
Fig. 2 is the utility model wind power generation device structure schematic representation.
Embodiment
See also Fig. 1, the generator of the utility model wind generating unit comprises stator 1 and rotor 2, and wherein, stator 1 comprises that main shaft 11 and the stator frame 12 that is fixed on the main shaft constitute, and stator frame 12 is provided with the stator coil 121 that is planar alignment.In this specific embodiment, stator coil 121 is embedded in the stator frame 12.Stator frame 12 is made of the plastic cement of the parcel stator coil both sides that form at stator coil both sides casting plastic cement, and it adopts stator coil 12 is placed the stator frame mould, and the method for the both sides of stator coil casting plastic cement is made in mould then.Rotor 2 comprise coil 21 on the rotor, rotor lower wall 22, rotor distance ring 23 and permanent magnet 24.Coil 21 on the rotor, rotor lower wall 22 and the rotor distance ring 23 common rotor disks that constitute rotors.Coil 21 on stator coil 121, the rotor, rotor lower wall 22, rotor distance ring 23 and permanent magnet 24 all be provided with axisymmetricly about main shaft 11.Dish 21 and rotor lower wall 22 and are positioned at the both sides of stator coil by bearing 3 rotatable being connected on the main shaft 11 on the rotor, thereby make stator coil be held on the inboard of described rotor.Be connected with fan blade on the rotor 2, thereby fan blade rotates under wind action and drives the rotation of described rotor.Rotor distance ring 23 is used for determining the spacing between the dish and rotor lower wall on the rotor, and it is connected on the rotor between the dish and rotor lower wall and is positioned at the periphery of dish and rotor lower wall on the rotor.Permanent magnet 24 is fixed on the rotor inboard of dish and rotor lower wall, and with the clamping stator coil, thereby when rotor rotate, permanent magnet rotated and makes stator coil cutting magnetic line generation electric energy.For preventing bearing and rotor in the motion of main shaft axial direction, bearing 3 is clamped on the main shaft 11 by tightening nut 4.
Be to reduce the loss of copper cash under high frequency, stator coil 121 adopt multi-thread and around mode make, it is different from the coil of traditional solid wire coiling.The stator coil that adopts multi-thread and coiling of the present utility model to do, can be down long-pending in same cross-sectional, significantly reduce the loss of copper cash under high frequency, thereby reach the temperature that reduces stator coil, the purpose that improves generating efficiency by the copper loss (high frequency skin effect) that reduces coil.Adopt stator coil multi-thread and that coiling is done of the present utility model to compare the stator coil of traditional solid wire coiling, under equal rotating speed, cutting magnetic field conductor number is maximum, and therefore the induction electromotive force maximum more is applicable to slow-speed of revolution electricity generating device (perhaps breeze generating set).
For rotor can also can be rotated under the situation of low-force being subjected to, under the situation as gentle breeze, special bearing 3 is adopted the bearing of unlubricated, nonmagnetic, low inertia, to realize littler rotation friction, help realizing breeze start-up and improve generating efficiency.
Adopt multi-thread and around the advantage of the coil of the traditional relatively single line coiling of stator coil in order to explain the utility model more intuitively, special it be listed as follows:
| The coil modes of emplacement | Stator disc thickness | The designated diameter lower coil is placed number | Magnetic flux density | Cutting magnetic field conductor number |
| Vertical pile | Thick | More | Low | Many |
