Description
Technical field
The present invention relates to a kind of permanent magnet synchronous wind generator, especially relate to a kind of cooling rib direct driven permanent magnetic synchronous single bearing aerogenerator.
Background technology
The direct drive permanent magnetic generator of domestic and international each motor producer development, through actual motion, though generating electricity by way of merging two or more grid systems of having moves also unstable, reliability remains further to verify and improve, particularly, because also there are a large amount of problems in motor at aspects such as electromagnetism, heating and analysis of heat transmission, supporting constructions, make that the motor performance index is lower, temperature rise is unpredictable, control characteristic is bad, and motor is overweight, and transportation and lifting are very inconvenient, as easy as rolling off a logly causes mechanical deformation in hoisting process.For example, the 1.2MW direct drive permanent magnetic generator that the Vensys company of Germany produces and China company introduces adopts the structure of external rotor, internal stator, though. operational efficiency height, self-radiating poor ability, need to adopt the heat radiation form of inner secondary ventilation, could normally move.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of simple and compact for structure, good heat dissipation effect, the efficient height is convenient to the cooling rib direct driven permanent magnetic synchronous single bearing aerogenerator that transports and install.
The objective of the invention is to be achieved through the following technical solutions: it comprises end plate, support, stator, rotor, end cap, support links to each other with end plate, stator is fixed in the support, the support outer circumference is provided with radiating ribs, and stator and rotor are made of two concentric drums, is respectively equipped with winding and permanent magnet on their two relative surfaces, be fastened on respect to the stator rotor rotated on the outer ring of bearing, the inner ring of bearing and conical support and connection, the conical support is connected with end plate, and the bearing side that is positioned at the axial fan hub side is connected with brake.
The support of the present invention outside is provided with radiating ribs, utilize surperficial natural wind cooling, improve heat-sinking capability, perfect heat-dissipating, need not to adopt the heat radiation form of inner secondary ventilation, solved external rotor wind driven electric generator because of adopting inner ventilation, dust storm is to the etching problem of armature winding and permanent magnet, and protection effect is good; Adopt single bearing structure, make structure compact more; Adopt conical support fixed structure, make to form big cavity, make things convenient for the regular maintenance of device in the installation of axial fan hub and wheel hub, the blade, improve the heat balance of blower fan system, be convenient to the fixing and anti-lightning strike etc. of conduction of current cable at motor internal; Adopt permanent magnetic material to form magnetic field, reduced motor volume, improved electric efficiency, increased reliability of operation and useful life; Adopt overall structure, be convenient to on-the-spot the installation and transportation.
