Definitions

  • the technical problem to be solved by the present invention is to improve the structure of the rotor of the generator and optimize the magnetic field distribution on the trajectory of the coil to greatly increase the magnetic flux passing through the coil, thereby improving the efficiency of the generator.
  • Fig. 11 is a schematic view showing the curve L of the outer bend polarization.
  • the projections 11 are evenly distributed on the outer layer 12 of the rotor. Similarly, a similar structure can be found on the inner layer of the rotor.
  • the spacing between the two magnetic sheets can be adjusted.
  • the circumferential width of the inner and outer magnetic sheets of the double-layered rotor is proportional to the distance from the magnet to the generator shaft, or is close to proportional.
  • the opening and closing angles of the inner and outer magnetic sheets with respect to the axis of the crankshaft are nearly the same.
  • the outer magnetic sheet 20 and the inner magnetic sheet 40 have the same opening angle ⁇ , that is, their respective arc lengths along the circumference and their distance from the axis In direct proportion. .

Abstract

Génératrice éolienne équipée d’un rotor à deux couches, comportant un arbre moteur (5), un rotor (1) fixé à l’arbre moteur (5) et un stator (3) enveloppant l’arbre moteur (5). Le rotor (1) comprend une couche intérieure (12) et une couche extérieure (14) moulées d’un seul bloc. La couche intérieure (12) et la couche extérieure (14) forment une encoche en U, et des plaques magnétiques (20) de couche extérieure et des plaques magnétiques (40) de couche intérieure sont montées sur la paroi intérieure de l’encoche en U. Les plaques magnétiques (20) de couche extérieure et les plaques magnétiques (40) de couche intérieure sont montées par paires de polarités opposées. Des bobines (30) fixées au stator (3) sont prises en sandwich dans l’encoche en U entre les plaques magnétiques (20) de couche extérieure et les plaques magnétiques (40) de couche intérieure.
