WIND WHEEL OF WIND POWER GENERATOR Russian patent published in 2023 - IPC F03D1/06 

FIELD: wind energy.

SUBSTANCE: wind wheel of a wind power generator contains a hub made in the form of a plate, tubular spars and sail planes, pole pieces with short and long sides, between the long sides of which excitation sources are fixed. There is a gap between the long sides of the pole pieces and the tubular spars. Each long side of the pole pieces has a pair of slots for the guide elements. An additional fastening element is installed on the tubular spar between the plate and the outer end of the tubular spar. Between the additional fastening element and the long sides of the pole pieces there is a spring, which is in a compressed state at low wind speeds to ensure maximum clearance between the stator elements and the short sides of the pole pieces, ensuring a decrease in the specified gap with increasing wind speed.

EFFECT: improving the manufacturability of the design, reducing the starting moment and ensuring the acceleration of the wind wheel in weak gusts of wind.
