For solving the problems of the technologies described above, the solution that the present invention proposes is: a kind of skewed slot dual-stator permanent magnetic disc type wind power generator, it is characterized in that: it comprises left skewed slot stator, right skewed slot stator, p-m rotor, the hollow output shaft, first chassis, second chassis, middleware and control unit, described left skewed slot stator and right skewed slot stator are oppositely arranged and are individually fixed on first chassis and second chassis, p-m rotor is fixed on the hollow output shaft and between left skewed slot stator and right skewed slot stator, described hollow output shaft is installed in the central through hole place on first chassis and second chassis, and described first chassis links to each other by middleware with two ends, second chassis.
Described control unit comprise the left three-phase stator winding that links to each other with left skewed slot stator, the right three-phase stator winding that links to each other with right skewed slot stator and with the corresponding three-phase unit switch of above-mentioned three phase windings.
The upper/lower terminal of described hollow output shaft is respectively by the through hole of Bearing Installation in the middle of first chassis and second chassis.
Compared with prior art, advantage of the present invention just is:
1, skewed slot dual-stator permanent magnetic disc type wind power generator generator of the present invention has adopted the desk permanent-magnet generator of the design of flattening, disc typeization, low windage to become the main system of vertical axis wind power generation system develop actively;
2, skewed slot dual-stator permanent magnetic disc type wind power generator generator of the present invention has adopted the mentality of designing of a disc type left side and right special-shaped skewed slot stator core, has reduced slot effect and magnetic resistance moment that magnet steel and stator tooth produce;
3, skewed slot dual-stator permanent magnetic disc type wind power generator of the present invention has adopted the design of two stator winding, balance the magnetic pull of p-m rotor to two stator cores;
4, skewed slot dual-stator permanent magnetic disc type wind power generator of the present invention has adopted two stator winding designs, can make two output voltage, simultaneously, can move generating respectively by string or parallel way;
5, skewed slot dual-stator permanent magnetic disc type wind power generator of the present invention adopts the assembling of the two stator winding of disc type and single p-m rotor, and axial dimension is shorter, has dwindled the volume and the weight of generator;
6, skewed slot dual-stator permanent magnetic disc type wind power generator of the present invention, adopted the flattening design, it is special to have adopted simultaneously, and short hollow defeated axle goes out, the hollow short sleeve of generator is contained on the pitman shaft of windmill flabellum of vertical axis aerogenerator, is easy to realize the assembling of floating.Because the application of this kind assembly technology, generator and windmill are two independently flexibility combinations of assembly, so generator does not directly bear the weight from wind-force and windmill self.Simplify final assembly technology greatly, make the DIY installation become possibility;
7, skewed slot dual-stator permanent magnetic disc type wind power generator of the present invention has adopted the design of special-shaped skewed slot, so the magnet steel that embeds of rotor then can design and select minimum cylindrical of cost for use, and the production technology of p-m rotor is simplified, and cost can reduce.
