Summary of the invention
The technical problem to be solved in the present invention is at above-mentioned defective, a kind of wind-driven generator of compact conformation is provided, this generator makes full use of the remaining space of generator inside, under the situation that does not increase the whole generator volume, increase the rated power of generator, can conveniently solve large-scale magneto alternator transportation problem on land, and not increase extra Installation and Debugging difficulty.
In order to solve the problems of the technologies described above, the invention provides a kind of multilayer winding permanent magnet synchronous wind generator with following structure, comprise casing and end cap, its design feature is to be provided with at least in the casing two circles and is fixed on the casing and stator core in the form of a ring, and coil windings all is housed on each stator core; Be provided with the armature spindle that is rotatably connected on the casing and is used for being connected in the casing with power set power; Be provided with the rotor that is fixed on the armature spindle between the adjacent stators iron core, rotor is pressed close to be connected with on the surface of coil windings at interval and the polylith permanent magnet of uniform setting.
Described stator core is made as inside and outside two circles.
The present invention is under the situation of the overall volume that does not increase existing wind-driven generator, make full use of the remaining space of generator inside, two circles or the above stator core of two circles are set, on each circle iron core coil windings is housed all, be provided with rotor between the adjacent stators iron core, that is to say, each is drawn a circle to approve the coil windings of sub-iron core and all can generate electricity, under the situation of machine shape constancy of volume, can improve the power of generator greatly.
In sum, the invention has the advantages that: compact conformation, volume is little, and power is big, is convenient to transportation and installation.
