TWIN-ROTOR SOLENOID WIND POWERED GENERATOR WITH A TOOTH STATOR Russian patent published in 2012 - IPC F03D9/00 H02K21/24 

FIELD: electrical engineering.

SUBSTANCE: device refers to the wind energy, pacifically to the wind-energy equipment, designed to charge accumulator batteries and power supply for various recipients. The device contains a motionless stator winding solenoid type and two rotors made of nonmagnetic materials. Rotors have disk form and are placed in axial alignment. The same even number of permanent magnets is distributed on each rotor. Stator winding is reeled on the wind powered generator's axis and is placed between the two cylindrical cores made of the ferromagnetic materials. Large-diameter core is fasten from the outside in the body frame. Both rotors are placed on a single spindle which is connected to the wind wheel and has the ability to rotate in the bearing assemblies. The permanent magnets have a Pi shape. Their poles are placed in axial alignment on each of the rotor and are directed in a heteropolar manner towards each other. Each of the permanent magnets is with heteropolar alternating poles on each rotor has the ability of axial alignment placement with cylindrical core ends. Cylindrical core ends have serrate shape with number of serratures half as less as a number of the permanent magnets. Serratures are placed in axial alignment to each other.

EFFECT: enhanced directed EMF in the stator winding and facilitated stator manufacturing technology.
