DOUBLE-ROTOR TOOTH WIND-DRIVEN GENERATOR Russian patent published in 2011 - IPC F03D9/00 H02K16/02 H02K21/24 H02K1/12 H02K1/27 

FIELD: power industry.

SUBSTANCE: double-rotor tooth wind-driven generator includes stationary stator winding of solenoid type, as well as two rotors from non-magnetic material. Rotors are made in the form of discs and located coaxially. Equal even number of constant magnets is distributed uniformly on each rotor. Stationary stator winding of solenoid type is wound along axis of wind-driven generator and located between two cylindrical cores from ferromagnetic material. Core with larger diameter is fixed with its outer side in the housing. Both rotors are arranged on one shaft. Shaft is connected to wind wheel and has the possibility of being rotated in bearing supports fixed in the housing. Constant magnets are U-shaped, and their poles are located coaxially on each of the rotors and directed unipolar to each other. Each of constant magnets has the possibility of coaxial rotation with edges of cylindrical cores. Edges of cylindrical cores have tooth shape with number of teeth equal to number of constant magnets. Teeth of one edge of cylindrical cores are coaxial to slots of other edge of cylindrical cores. In each slot there located is connection strap from ferromagnetic material, which connects both cores.

EFFECT: increasing EMF induced in stator winding and simplifying the manufacturing procedure of stator winding.
