SOLENOID WIND GENERATOR WITH A TOOTH STATOR Russian patent published in 2020 - IPC F03D9/00 

FIELD: wind power engineering.

SUBSTANCE: invention relates to wind power engineering, namely, to windmills intended for charging accumulator batteries and power supply for various consumers. Solenoid wind generator with tooth stator comprises housing accommodating first cylindrical core accommodating second cylindrical core. Both cores are made of ferromagnetic material and interconnected. Ends of one side of cores are made with uniformly distributed teeth and grooves of identical area. Teeth of both cores are coaxial to each other. Between the cores along the windmill axis there is a fixed solenoid-type stator winding connected to leads. Shaft is located inside the second core with possibility of rotation in bearing supports and is connected to wind wheel. On the shaft there is a rotor made of nonmagnetic material in the form of a disc, on the surface of which the even number of constant U-shaped magnets is uniformly distributed, while their poles are located coaxially and directed in different polarity to each other on the surface of which faces the teeth of cylindrical cores. Each of permanent magnets with different polarity alternating poles is made with possibility of coaxial rotation with ends of cylindrical cores. Number of teeth at ends of cores is equal to half of number of permanent magnets. Both cylindrical cores on opposite side relative to rotor have smooth ends, coaxially fixed to yoke of nonmagnetic material in form of disc, on surface of which, facing smooth ends of cylindrical cores, there are even number of permanent U-shaped magnets, poles of which are located coaxially and are directed different polarity to each other. Number of magnets on the yoke is equal to the number of magnets on the rotor, besides, each of the permanent magnets is pressed to smooth ends of the cylindrical cores with different polarity alternating poles. Shaft is installed in bearing supports located in the end cover of the housing and in the yoke.

EFFECT: disclosed is a solenoid wind generator with a tooth stator.
